Natural laws at play in CLL-Theory

In all the pathology, there is no disease that makes so much sense than Chronic Lymphocytic Leukemia disease I will beg to venture.  Our understanding of this disease has grown so rapidly that what is left to discover is probably not as much as one may think.  What is needed today is a reorganization of what we know and minute details particularly at the Nuclear levels.  The disease affects about 15000 people, and kills about a third of our people who happen to have gone in a wrong path because of a genetic failure particularly in our way of managing infections and cellular death.   And along these paths, there are laws that need to be followed, and any failure of following these laws leads to these dangerous disease called CLL.
The first observation to remember following this theory is that there is no clear environmental disaster that can induce CLL directly unless people exposed have a genetic failure in their cellular death control!  CLL is the only type of leukemia not noted after the Chernobyl Nuclear Reactor incident and there no correlation with CLL with other chemicals or Benzene exposures!
Infections however have a demonstrated activity in CLL occurrence.   Scientists will tell you tha disturbances of the NF-KB, NFAT and STATs are commonly found in this disease.   With the Infections, one can quickly conclude that Cytokines and growth factors are and must be involved and they are  (ie. disturbance at IL4).  (Adenopathies'swelling is a result of cytokine activity!)   These are common occurrences, why is it that CLL is not why spread?

1.For CLL to occur, you got to have disturbance in the law against cellular death.

The first evidence for this is the fact that mainly and or only disturbance in DAPK 1 (Death receptor) has been clearly and convincingly demonstrated to be found in familial CLL.  There is a law of nature that says, "to fight infection, the cell must close the door to programmed death, But Apoptosis must happen when certain circumstances are met".  In CLL, This last portion of the law must not be met!  The B cell involved, most likely a memory cell, has gotten rid of genes that fulfill this last portion of the law!  They forget the notion of death.  It is not by mistake that sometime up to 98% of CLL cells have deletion of 13q14 which removes the regulator of Bcl-2  (miR16).  And it is not by mistake that there is an expansion of of Bcl-2, bak ,  Mcl-1 and XIAP reported in the literature.  (and try to find bax or caspases, they are profoundly "suppressively" disturbed)  All are a consequence of relatively total suppression of Apoptosis.  Now wonder why the cells of CLL are mature non dying cells!

2.The law of desensitization.

When an antigen, or any stimulant persists at a receptor, natural laws will kick in to engage desensitization. Nor desensitization has been normally described as decrease in receptors.  The reality is just a it more complex.  As a matter of facts, decreasing receptors which are proteins assumes decreasing gene or gene expression  but the reality can be more severe!  Gene could be mutated or silenced, or fully deleted.  Sometimes the full arm containing the gene could be lost.  There are many deletions in CLL and silencing of promoters (ID4, SFRP family and even DAPK) is notoriously common.  Desensitization can start at receptors, G proteins to miRs and Chromosome arms removal!  This happens for proteins involve in regulations of cytokines, regulators of many involved genes, and hell, even Glycogene regulation is deranged in the process!  The law of desensitization is violated big time here!  In presence of chronic stimulation, even The IgVh region is Mutated! (a strong prognosis in CLL)

Abruptly you find yourself facing the inadequacy of current Biomarkers for CLL.  But things are coming your way with a vengeance and soon!   The CRBCM is following...!

Some genes of interest

1.MTNR1B : A MELATONIN GENE
" insulin levels also exhibit a nocturnal drop, which has previously been suggested to be controlled, at least in part, by melatonin. This regulation can be explained by the proposed inhibitory action of melatonin on insulin release." Mulder et al.

This gene has been linked to gestational Diabetes and some have used it to secgregate patient with propensity to Diabetes Mellitus type 2.

2.HHEX
" HHEX serves to repress VEGFA, another protein which is important in endothelial cell development."wikipedia...Can it play a role in angiosarcoma?
PAZ et al " Hhex is a critical regulator of hematopoietic development and is necessary for the maturation and proliferation of the earliest definitive hematopoietic progenitors."
 HHEX interacts with SOX13
" SOX13 is known to repress Wnt/TCF signaling by interacting with TCF1. We show that Hhex is able to block the SOX13-dependent repression of Wnt/TCF activity by displacing SOX13 from the SOX13·TCF1 complex."Marfil et al

"Otx2, and Lim1 appear to promote hhex transcription through homeobox sites in a Wnt-responsive element located between −0.65 to −0.55 Kb of the hhex promoter. (2) Siamois/Twin also induce the expression of the BMP-antagonists Chordin and Noggin, " RANKIN et al

for CRBCM, role in pancreatic cancer, liver cancer and thyroid cancer needs further clarification

3.Cytokynes (EPC)-JAKs---STAT 3,5----Bcl-xL ----CYTOCHROMEC---CASPASE9-  (WIKIMEDIA)
is this the mechanism of PTSD.?

Prevention and monitoring following cellular zones

As predominant abnormalities of genes are more described as they are specific to each cancer, most likely location of genes in the cell could further characterize gene location for further development of prevention intervention.
These interventions may include:
-gene modification (morphologic, post translational modifications, and otherwise...)
-gene activation that induce overexpression
-gene suppression which induce deactivation (PTEN)
-gene silencing (through methylation and other complementary molecules)
-etc...
Whether you approach the gene targeted for intervention by standard approach or nanotechnology, it is important to predict where you are more likely to find this gene.  Is the gene more likely in the extracellular matrix (Metalloprotease) or in the Nucleus or rether in the epigenic zone.  Where is the gene that is more likely to be other mutated, over expressed or suppressed.

Most of the times, given the light speed of interactions and travel down the pathways, where to intervene may not be relevant, but increasing the odds force scientist to locate intervention points.  ie, Patient with lobular cancer with history of Familial Gastric cancers are known to have E-Cadherin abnormality, focusing prevention efforts on the membrane, will go a long way than focusing studies on Telomeres...

OUR OLD EXPERIENCE HELPS ! LAS VEGAS ROCKS!

Yes as a drug gains more indications, the past experience makes it easier for Oncologist practitioner to re-use drugs they have been used to!
For Hepatocellular Carcinoma, the drug on the mind of all oncologists is NEXAVAR, yeah, we have been accustomed to managing its rashes and Diarrhea, and watch its marrow suppression.  A combination of weekly visits and then monthly for our patients to start with!
Well it is the same dance once again in Metastatic thyroid cancer, the kind of Metastatic progressing and resistant to Iodine based treatments!   NFX1 OR SHOULD WE SAY
 NBCI-gene "Inappropriate activation of NFKB has been associated with a number of inflammatory diseases while persistent inhibition of NFKB leads to inappropriate immune cell development or delayed cell growth.'
Jing Du et al:"Correlation analysis revealed that there was a positive relationship between the level of HPV16 E7 and the expression of p65. The correlation between E7 and p53 was also significant, although to a lesser degree"
IT'S NOT JUST P65, BUT P300, P25
AND THE NOTCH1 IS NOT FAR ! MEANING VEGF-A-DELTA,JAGGED1,AND A SLEW OF
MIR (s) AND SF3Bs, NOT TO MENTION TENACIN AND CADHERINS!

LAS VEGAS WILL STAY ON OUR MINDS FOR A WHILE, RESPECT SILTUXIMAB FOR THIS!

*How in the world can you succeed this!  But Siltuximab did, BE INDICATED IN A RARE FORM OF A RARE PRESENTATION OF A RARE DISEASE...
EVEN WIKIPEDIA DEFINE :
"Multicentric Castleman disease (MCD) involves growths at multiple sites.[8] About 50% is caused by KSHV, also called HHV-8, a gamma herpesvirus that is also the cause of Kaposi's sarcoma and primary effusion lymphoma, while the remainder of MCD are of unknown cause. The form of MCD most closely associated with KSHV is the plasmacytic form of Castleman disease while another pathologic form, the hyaline-vascular form, is generally negative for this virus."

BUT  SILTUXIMAB IS:

"On April 23, 2014, Siltuximab was FDA approved under the brand name of Sylvant[11] for the treatment of patients with multicentric Castleman’s disease (MCD) who do not have human immunodeficiency virus (HIV) or human herpesvirus-8 (HHV-8).[12][13]"WIKIPIDEA

WATCH THE 2  AND GO FIGURE!
BUT LET'S GRANT IT, IT IS STILL AN ANTI-INTERLEUKIN- 6, A FACT TO BE KEPT IN MIND AS WE LOOK INTO TBI AND PTSD!   CRBCM IS WORKING HARD!

LAS VEGAS conference III Mantle cell

We first saw the Death of CHOP/R-CHOP in this disease
Now we see the death of Modified HyperCVAD
Today we see the rise of Ibrutinib-Rituxan in the firt setting of disease treatment
than only come Idelalisib
and ABT-199
and may be HyperCVAD
and if you think of Bendamustine-Rituxan (after failure of Ibritinib), do not forget Maintenance therapy with Rituxan (rather than Interferon)

(as a note, in Europe R-CHOP/R-DHAP but is there a need?) (trying to be controversial here, am I successful?)  CRBCM, we take things in strides!

BUT IN THIS DISEASE, BENDAMUSTIN -RITUXAN MAY BE BETTER THE R-CHOP!
*WATCH THE MIPI

SEE
 "

The Mantle Cell Lymphoma International Prognostic Index (MIPI) is superior to the International Prognostic Index (IPI) in predicting survival following intensive first-line immunochemotherapy and autologous stem cell transplantation (ASCT)

The Hematologic malignancy review has been completed in Las Vegas II....CLL

In CLL

*?review role of Thyrosine Kinase in CLL
*Prognosi factor remains the same (17p deletion, 11q dletion, ZAP70, etc.)
*CLL remains an uncurable disease
*FCR better than FC
*FCR better than Bendamustin -Rituxan despite more infection which does not impact mortality ultimately, and particularly in the young? (And who thought FCR lost its luster before Bendamustine-R ? watch for 17p deletion though and pick carefully!)
*17p deletion better treated in clinical trials
*Omecetaxine, an alternative approach to treatment
*Therapeutic choices
1.FCR
2.Benda-Rituxan
3.New anti CD20
4.Ibrutinib
5.Idelalisib
6.BCL-2 antibody
Obinutuzumab always used with Chlorambucil :"The monoclonal anti-CD20 antibody rituximab, combined with chemotherapeutic agents, has been shown to prolong overall survival in physically fit patients with previously untreated chronic lymphocytic leukemia (CLL) but not in those with coexisting conditions. We investigated the benefit of the type 2, glycoengineered antibody obinutuzumab (also known as GA101) as compared with that of rituximab, each combined with chlorambucil, in patients with previously untreated CLL and coexisting conditions." NEJM.

The Hematologic malignancy review has been completed in Las Vegas I....CML

In CML  (Information to be rechecked in the literature)
-Cytogenetic recovery becomes even more important as it guides
1. quality of response at 3,6,12 months and should be 10, 1 and 0.1% of the quantitative PCR
and failure to do so impact of patient survival
(MR less than 10% at 3 months, linked to 96% survival at 4 years whereas more than MMR>10% at 6 months is linked to 69% survival at 4years!)
2. direct impacting the survival
*Failure to meet that end point, particularly at 3 and 6 months, should prompt Cytogenetic Mutations reevaluation and based  on Mutation found pick the right TKI
*T3151---definitely Ponatinib or go to transplant (Allogeneic)
*Y253 and others---Dasatinib
*V299 and others---Nilotinib

*At 6 months, if Molecular response not met,
-check for adherence to treatment by the patient, and check for Mutations (ABL kinase domain point Mutation pattern assessment)

That now Major molecular response (MMR) could be expressed as , or MR 4.5

*Recognition that Frontline treatment is changing to 2nd generation TKI (Dasatinib, Nilotinib) but there is recognition that cardiovascular events are more frequent with these agents  ( and Pulmonary Hypertension-particularly with Bosutinib?)

*There is a recording of 4 year survival data (Dasison) MR4.

*Reduction in Ponatinib dosage from 45 to 30mg could reduce lvel of Arterial Thrombosis, and  hypertension rates ?without questionable effect on response rate.

Potential future collaboration lead at CRBCM!

"Thanks Peggy for your quick response,

As I mentioned to you last week, there was a potential collaboration with an oncologist in China. The story was that I met a clinical oncologist, Dr. Baofa Yu, who used be a research assistant professor at UCSD. When I was in Scripps Res. Institute in San Diego, I have known him quite well. He has returned to China about 10 years ago to establish private tumor hospitals using a therapeutic approach he developed to treat cancer patients (He has US and China Patents) . It was very successful. Currently, he has owned four tumor hospitals in China (in Beijing and other cities). He has interest in collaborating with an oncologist in US to use his novel approach to treat cancer patients. I have introduced our research collaboration to Dr. Yu on phone last week. He has great interest in collaborating with Dr. Kankonde. Dr. Yu may come to US for a visit in this coming July. Maybe we can meet here at El Paso. Dr Yu let me tell you that if it is possible, Dr. Yu would also like to invite you to China to visit his cancer hospitals in the near future."

The CRBCM will be honored to learn from DR Yu...
The future will be bright!And only the future will tell!

A critical Function down the neoplastic transformation : NPM1

As we test gene mutations with the UTEP team, one of the Mutation detected in the sera of lung cancer patients was Mutation or over expression of NPM1.  The literature suggested that this gene is a critical path to closing of natural ways to apoptosis while exacerbating cell division.
Indeed we all know that cancer is  characterized by cellular persistence, and longer life relative to normal cell.  This fact is more seen with Leukemic cells and NPM1 will be more present in these diseases as a matter of  facts.   To escape cellular programmed death, cancer will use NPM1 and related molecules to escape normal death particularly in the presence of abnormal genetic alteration often present in cancer cells!
It is not by mistake that NPM1 will have interactions with
1. BRCA that affect gene repair
2.P53 to close that reflex cellular arrest
3.Runx genes in hematopoietic malignancies  (proof of promoters'activities)
ARF, etc...   for some, RUNX is a part of CBFs
The activities into suppression of programmed death can even be measure by drop in Caspase 3,8 as reported by bright scientists!
  The second fold is of course promotion of cell division mainly through the Nucleoli and division of centromeres.   NPM1 expression appears bad prognostic indicators but has been cited in some leukemia of the young as a good prognosis indicator?   And that is most likely because it is a secondary events rather than truly a driver mutation?
Clearly it was striking to find it sitting there in Lung cancers!

More than 40.000 reviews in less than 2 years! The CRBCM!

With over 40,000 reviews, the CRBCM is advancing slowly but deliberately
our cause is just that is why we are still alive,
will stay alive long enough until enemies become irrelevant!
We are still advancing as more is being done,
and somehow we keep staying alive by the grace of God!
40,000 reviews and counting in less than 2 years ...we can be proud and the need is there!
we will keep on progressing until we get to the promised "land"....

Ramucirumab, FDA approved in Metastatic GE Junction and gastric cancer, but is-it all?

May be Ramucirumab will work
At CRBCM we have a patient who has Angiosarcoma in the liver who had a rapid progression on Gem-Taxane (in fact she had a very powerful allergic reaction to Taxane) and again progressed on MAID
She was switched to Avastin alone since the reaction to Taxane was strong. The disease remains stble for 1 year.  She has now vaginal bleed and acute SOB that responded only to steroid, Avastin has benn on hold
It is unclear if she will tolerate it again.
Alternative Pazopanib?
?Trabectedin (unavailable in the US?)
Cediranib?
or is-it the new Ramucirumab?  will try with Lilly!

The process of Neoplasia in lung cancer, potential for screening through blood!

Lung cancer, one of the leading deadly cancers for which screening has not clearly be established, has been one of the target of many researches.  To this day, only radiological evaluations have creeped up to a level of screening.   With the advance of technology, we have gone from Chest Xray to low-dose cat scans for this indication.  And this despite our progress in the knowledge of genetics.

Quite frankly it seems that much of preliminary genetic knowledge has been developed.  The amount of information available on genes of cancer is impressive.  What is missing is boldness of our scientists to form theories of progression of this disease which kill many victims each year.  The neoplastic process however continues to occur steadily, and year after year, new lung cancers are being brought to light through detection that is characteristically late.  There are many lung cancers and none appears to have the same pathophysiologic occurrence mechanism.   So in this maze of mechanisms, finding a steady gene abnormality that does vary very much through stages of cancer appears a significant fact!  Indeed the MDM-2 Mutation appears steadily throughout the stages of certain lung cancers, particularly the Adenocarcinomas.  Mouse double minute 2 homolog (MDM2) also known as E3 ubiquitin-protein ligase is the gene in question!  In our sample, this gene was the highest present and its presence seemed to vary little both on cancer tissues and in the serum of diseased patients.  These specimen were provided to CRBCM and the UTEP biologic research laboratory by LCBRN -VA university tissue bank (under MDHONORS funding).

Coming back to the MDM-2:
------------------------------

When one lean on this finding in depth, the puzzle for the involvement of the MDM-2 runs deeper than first suspected.  And clearly lays in the dawn of the neoplastic process.  And as we lean further, new suspicions rise that the onset of the neoplasia for some cancers is here! Several facts contribute to this perception.  We all know that cigarette smoking is a common cause of lung cancer, and now this known fact...
Dr Yurong Chai, our investigator stressed that Cigarette smoke "increase the risk of alternative MDM-2 splicing" a fact that establishes the initial event that will trigger so much subsequent genetic calamities.   MDM-2 happens to be the regulator of P53.  It also has a competitive partner, the FKBP25,
OCHOKA"
"The p53 tumour suppressor protein is tightly controlled by the E3 ubiquitin ligase, mouse double minute 2 (MDM2), but maintains MDM2 expression as part of a negative feedback loop. We have identified the immunophilin, 25kDa FK506-binding protein (FKBP25), previously shown to be regulated by p53-mediated repression, as an MDM2-interacting partner. We show that FKBP25 stimulates auto-ubiquitylation and proteasomal degradation of MDM2, leading to the induction of p53. Depletion of FKBP25 by siRNA leads to increased levels of MDM2 and a corresponding reduction in p53 and p21 levels. These data are consistent with the idea that FKBP25 contributes to regulation of the p53-MDM2 negative feedback loop."   The impact on a member of the FK506 family has deep implications both on the disease process and therapeutically as we may discuss.
The involvement of disturbances of the MDM-2 has even deeper consequences, because of independent MDM-2 activity directly on initiation of  DNA replication and through its activity on Cyclin-depedent Kinases!   The MDM-2 rise quickly as a biomarker of Cancer initiation and therefore a major Biomarker of the danger of smoking!  And its presence no matter the stage of disease has several implications including that of how you appreciate curability!  (to be continued)

We had our last meeting with DR CHOI at UTEP!

Yes yesterday was our last face to face meeting with DR Choi a brilliant scientist working at UTEP
with DR Zhang. She is returning to China within a week.  She transformed our world of suspicions into real events.  She has been a dominant force and a matter of facts woman who has key to our project on lung cancer detection kit  development project.
She did the PCR work needed and open us up to new perspective on the 3 genes looked at that not only confirms our suspicions, but opened new perspectives for future research questions related to the 3 genes.
Her findings have reaffirmed that we are in the right path and raises significantly the importance of target therapy, strengthen the notion that Ubiquitylation is critical in the initiation of lung cancers (and other cancers)
and could probably be a potent biomarker ( by its disturbances) to smoking danger to initiate lung cancers.
In the sera of patients  with lung cancers, her findings have been just as stunning and intriguing.  From high Cyclin presence to the presence of antibody for NPM1, p16 and even in minutes amount the presence of 14-3-3  (the same found in Creutzfeld Jacob disease ?).  All these findings were captivating and raising new questions about the specificity and sensitivity of some of our tests.
The level of amplification of these abnormal genes certainly call for a cut of point for amplification that could be primary and be suspected to be neoplastic, or secondary that could be an unintended event subsequent to other gene's amplification whether malignant or not.
When it comes to Antibody, what we suspected was confirmed.  Indeed since the antibody secretion is function of fluctuating lymphocyte reaction, or cellular use of genes involved in raising attraction of the white cells, the levels of antibody is fleeting or not correlating with the presence of gene amplification.   But our findings is that in cancer the presence of antibody is confirmed.  This may help in early detection...
Our discussion also brought to mind the difficulty of perceiving or detecting gene suppression unless your sets include normal tissue (we were offered biopsies of surrounding tissue luckily).  Finding genes that are less expressed is critical.  The example would be the suppression of PTEN in lung cancer, a well published event.  Unless you are comparing with surrounding tissues in the same individual, establishing repressed gene could elude your observation.  And we know how important such an observation represents as in major neoplasia, regulator genes could be suppressed!  Our work is still preliminary, and may be revisiting, but clearly new perspectives have been open and our work will continue no matter what!
CRBCM is progressing deliberately.  Please wait for the publication as it is being finalized!

Dangerous precedent about VIAGRA, its connection to Melanoma!

The risk association of Melanoma with Viagra raises significant fear for those who have no genetic background because Melanoma is still one of the most dangerous and untreatable cancer at advanced stage.  For the scientist, this open the door to further research into gene interactions.
Melanoma is a disease that raises fear in the community given its fatality in advanced stage. In the Untited states it kills close to 9000 lives yearly or more than 10% of affected individual globally.  The gene involved is p16/CDKN2A which encodes for both p16 and p14ARF.   It is worth mentioning that Xeroderma pigmentosum and BRCA2 predispose to this disease.  Also loss of PTEN has been cited for association with Melanoma.    GNAQ/GNA11 has been associated with Uveal Melanoma.  c-KIT has been cited in Lentigo maligna Melanoma.

Viagra, suppressor of the enzyme phosphodiesterase type 5 (PDE5),will block degradation of Cyclic GMP necessary for Erection performance.  What this has to do with PTEN. CDKN2A, and may be p14ARF or BRCA2 becomes of interest.  Other then standard Erection dysfunction, Viagra has been used more chronically in patients who have Pulmonary Hypertension, a silently deadly condition.

This elevated risk of melanoma does not come as a surprise however and more discoveries are upcoming for certain since the Cyclic GMP, like Cyclic AMP are "second messengers" affecting many pathways given their position early in these pathways.  The observation also point to the danger of chronic exacerbations of genes in any pathways.  The reactions occurring in a cell to adjust to excited gene could be deleterious as it can either exacerbate or suppress compensatory pathways, leading to cancers.  Another independent fact is the fact that "second messengers" have been used in the past for Biomarker of chemical molecule activity...and Cyclic GMP is a "messenger", a clear Biomarker of event to come in a cell!

Hyperlipidemia "under the microscope", REDUCING RISK OF CORONARY AND BLOOD VESSEL DISEASES

-does Xanthelasma, Corneal arcus, provide clues in triglyceride deposition in the artery
-does minimal pancreatitis and similar induced inflammatory disease induced by hyperlipidemia contributes to Coronary disease
-what type of inflammatory process are produced by free fatty acids and related lipid molecules
-?associated Pulmonary hypertension
-Dysbetalipoproteinemia provides more clues to pathophysiology?
-Cytokines involved in Neurologic syndrome of Chylomicronemia or is it direct disruption of lipogenesis/lysis
-What is the role of IL-6 in all this mess, can controlling IL-1 & 6 help (ie preserve elasticity of blood vessel)  could vascular cellular preservation slow down Arteriosclerotic phenomena (preservation of elastin and related compounds)
-what is the role of cytokines in vascular transformations (AS CYTOKINES INDUCED BY FFA)
-should closer elective follow-up of the pancreas serve as a biomarker of hyperlipidemia
-should early xanthoma be allowed to alert of Coronary event due to hyperlipidemia, FFA levels?
-what is the role of TSH, and the thyroid?
-what in the urine analysis predict a coronary events (as it relates to lipid)
-What Vitamins have to do with this?  Vitamin D role?
-Eruptive Vs tuberous XANTHOMAS (FAT VS CHOLESTEROL) WHY AND WHEN?
-how to consume debris of lipolysis without causing a "Cytokine storm" or an autoimmune disease
is it through IL-6
-how does specific  medicines works to minimize cytokine storm?
-How does Ileal bypass affect the cytokines, vascular transformation, should it be routine at a certain age to reduce Coronary risk
-can sonogram of the pancreas, specific artery gives a clue on coronary disease due to lipid disruption

Genes to Eternal life

According to the US Government on Aging (at least seems to suggest)
to have eternal life you have to have or know some of the genes for these functions:
-Gene(s) to avoid unhealthy choices (ie. blocking Glucogen,controlling lipid,MTOR, CRE gene)
-Genes to keep life sparks (hormones,cytokine,physical exercise,what to eat)
-Gene(s) to keep eternal  youth (Telomeres,MTOR)
-Genes to stay spunky (hormone,routines, MTOR
-Genes that keep you fun (Hormones, cytokines)
-Genes to keep magical transformation (rejuvenating) (Cytokines,
-Genes to avoid physical decline (Exercice under cytokine control
-Genes to avoid vulnerability to disease (Flyn,Lyn directions for looking)

let's go find them!

search for the "OBLONG" pill.

"Oblong man" rather than "circle man" infers less obesity
Obesity is a growing issue in the United States and many want to find an answer to obesity by coming up with a "pill" that will make people lose weight...the "Oblong Pill" is such a pill.
while many reports "fighting" against obesity, few patients with autoimmune diseases are reporting to us for inability to gain weight!  In Autoimmune diseases, we surmise that cytokines induced in this disease significant perturbation of both glucogenesis and lipogenesis-lysis.  The logical conclusion is that isolating the cytokines involved may help with weight management.  But in autoimmune disease we could also localize relevant biomarkers that mark the increase in cytokines.   We could also test why cellular proliferation does not occur (is it through FOXO3), and measure transformation in lymphoproliferative disorders (is it through the LYN, RELA etc?). Should we avoid these types of development and what would be the type of warning that these mechanisms are elicited .

Bani-Sadr et al "Weight loss is reported by more than 20% of hepatitis C virus (HCV)-monoinfected patients treated with the peg-interferon (peg-IFN) and ribavirin combination."  and indeed chronic use of interferon is accompanied by weight loss.  Interferon belong to the Cytokines, another proof that Cytokine may be an answer to Obesity if controlled and managed carefully!

Joyce A. O’Shaughnessy, MD

 
 
Dear Colleague,
I invite you to attend the 13th Annual International Congress on the Future of Breast Cancer® to be held from Thursday, July 17, 2014, through Saturday, July 19, 2014, at the Hyatt Regency in Huntington Beach, California.
This event has become a yearly highlight for the community oncologist specializing in breast cancer.

role of TPI gene in cancers

OROSZ et al:
"One of these, triosephosphate isomerase (TPI) deficiency, is unique among the glycolytic enzyme defects since it is associated with progressive neurological dysfunction and frequently with childhood death. The physiological function of TPI is to adjust the rapid equilibrium between dihydroxyacetone phosphate and glyceraldehyde-3-phosphate produced by aldolase in glycolysis, which is interconnected to the pentose phosphate pathway and to lipid metabolism via triosephosphates."

*SABiosciences Regulatory transcription factor binding sites in the TPI1 gene promoter:
         c-Fos   PPAR-gamma1   AP-1   ATF-2   PPAR-gamma2   c-Jun   c-Ets-1 
         Other transcription factors

*development of Giardiasis is a potent sign of this disturbance
*Is TPI involved in salivary gland cancers
*does supplying G3P +DHAP resulting product correct this disease?
*what is the expression of REB1,RAP1,GCR1 in salivary gland cancers?
stephens et al: on Adenoid Cystic Cancer ( fusions of the MYB-NFIB genes)
"We identified multiple mutated genes that, combined, implicate chromatin deregulation in half of cases. Further, mutations were identified in known cancer genes, including PIK3CA, ATM, CDKN2A, SF3B1, SUFU, TSC1, and CYLD. Mutations in NOTCH1/2 were identified in 3 cases, and we identify the negative NOTCH signaling regulator, SPEN, as a new cancer gene in ACC with mutations in 5 cases. Finally, the identification of 3 likely activating mutations in the tyrosine kinase receptor FGFR2, analogous to those reported in ovarian and endometrial carcinoma, point to potential therapeutic avenues for a subset of cases."

Delayed Response to Ipilimumab

This case of delayed Melanoma response to Ipilimumab is clearly puzzling and raises the question of the appropriateness of our measurement of disease response to treatment in solid cancers being treated with Immune approach.  The need for "Immune Response Criteria" or Biomarker is clearly here!
We block CTLA4, a lymphocyte related molecule but we stick to the mass volume criteria to assess response when indeed activation of lymphocytes should be the criteria.  One would think that Adenyl Cyclase activation would be the first proof of Medication activity since most pathways will pass by this?
gene activation would be best bio-markers and attraction to the tumor would be best quantified here (by certain gene activation)
Dampening of B7, particularly with closure of  related downstream genes would make a stronger indication of disease response...And we know suppression of receptors is marked when this happens.
The awakening of the Lymphocyte theoritically should raise the possibility of inducing Inflammatory  process in some patients based on genetic heterogeneity (which is the question behind this possibility), in the case presented, an inflammatory bowel disease was reactivated...did the patient present such an genetic atopy or background?  does use of steroids contribute to the delayed response or is-it the other way? that is genetic back ground actually drives the delay in response?  which background? IBD? (the fact is that in the case presented, one of the metastatic Melanoma mass involved the Colon provide further clue as to further link of this Melanoma with the GI tract could be surmised!)   The resection of this mass is an heroic activity that struck me !  most clinical settings would not have tried this exercise deemed futile in most American institutions...a paper should be provided just on what prompted this resection...please tell us what prompted the resection of a metastatic Melanoma lesion?it is puzzling but at the end a good thing for this patient!

few investigation questions in various diseases

What testosterone gene has to do with Hairy cell leukemia
What HLA has to do with Hairy cell leukemia (why the incidence in black is lower?)
Weight loss is linked to Cytokine discharges which interfere with Gluconeogenesis?
Organomegaly is linked to disturbances in the Catenins, protein mobility in the cells, or "cellular flagellation" ? but why?
Interesting this hairy cell, leads to hypocholesterolemia? what cytokine does this again? should it enter therapeutic trial?
Is it the Annexin A1,  what TRAP has to do, BRAF-V600E (activity of Vemurafenib in Hairy cell)
what cytokine lead to collagen or reticulin expression in this disease?
High dose interferon works in this disease!   Yes a Cytokine works (where is my Cytokine bank!)
The disease brings back a fundamental question, why susceptibility to infection, is it weakness in the mitochondria?is it the LYN gene, c-MYB or disturbance in the Ig.
Why vasculitis in this disease?  disturbance of G-proteins?

ALL STROKE PATIENTS UNDERGO A CYTOKIN STORM AND SHOULD EXPECT PTSD!

And once again we tremble to recognize that all stroke patients will suffer PTSD or post traumatic stress syndrome even though it is the basic principle and process that will and have happened
and will fluctuate based on our genetic heterogeneity, location in the brain, and intensity of cytokine.   The reaction of cytokines could actually be predicted for each of us prior to event as we can test Macrophage reaction before hand!  And knowing the genes,
and Early administration of MTOR inhibitor and interferon  (or Sirtuins) like products could indeed dampen the Cytokine storm and minimize maximally the effect of a stroke!  But we still wait to test what we know !
Here we stress  the need to know our inflammatory index as age or status of our vascular status. we also stress the need for a camera deep in  vessel to check our thrombus stratus and status. and report which thrombi are on the "brink" of collapse. Forget measuring by EEG, we are past Aspirin and plavix, the treatment of stroke is on the cytokine and the Macrophage! (what is Adenyl cyclase doing?)  An "homocystein" and related gene system system will tell us if a thrombus somewhere is about to break!  And gene activation (ie "cytokines or growth factor index") will tell physician how hard our blood vessel is!  Are they ready to break?!   Following blood pressure alone is not enough and has failed us!  medicine of tomorrow is just genes!  genes and genes!  25000 only and we can't read them despite all our computers!  Lets go back to work!

New areas of investigation in cancer research

Can Cisplatin be used to stop recalcitrant Viral hepatitis load  ?
or a combination of Cisplatin and Sunitinib or Imatinib
what is the relationship with RFX-1

" treatment with retinoic acid induces both MIBP1 and RFX1 protein, as well as their DNA-binding activity,"Z-Kaye et al.     (Is there promotion of c-MYC in APL by retinoic Acid use)
Lubelsky"derepression of the RFX1 gene is only partially blocked by inhibiting Chk1, the DNA checkpoint kinase."...." Rfx1 binds and represses its own promoter. Furthermore, Rfx1 binding to its promoter is reduced upon induction of a DNA replication block by hydroxyurea," A dangerous gene by its ability to self promote and repress.  Mutation here could have cataclysmic consequence, worth while checking number of this mutation in CML, and whether this would be a clone responding better to Hydrea?

how frequently Testicular cancer present with this Mutation
Is an indication that Hydrea could replace the bad, dangerous Bleomycin?

What is its (RFX1 mutation) presence in Thyroid cancer
Can Hydrea work there?
should Anaplastic thyroid cancer therapeutic combination include Hydrea when RFX-1 is over expressed?
Is RFX1 a biomarker for Hydrea activity?  Can Cisplatin be associated to booster the effect?
==========================
do not confuse with NFX-1 implicated in Papilloma Virus but acting strangely the same as it come to penetrating the Nucleus? or may be they are both epigenetic, but this one linked to p109 according to the Seattle People!

"Urology was consulted and recommended induction chemotherapy and consideration of surgical consolidation after chemotherapy. The case was discussed extensively at tumor board. The consensus was that cisplatin-based chemotherapy is an essential component of potentially curative treatment, so the planned treatment included reduced-dose etoposide and cisplatin with aggressive IV hydration along with renally dosed allopurinol given the bulk of the tumor."
 Tim McCarthy.

A randomized trial of cisplatin, etoposide and bleomycin (PEB) versus carboplatin, etoposide and bleomycin (CEB) for patients with 'good-risk' metastatic non-seminomatous germ cell tumors.

Abstract

BACKGROUND:

Cisplatin-based combination chemotherapy will cure 70% to 80% of patients with metastatic non-seminomatous germ cell tumors but is associated with the possibility of severe neuro-, oto- and nephro-toxicities. Carboplatin, a cisplatin analogue, is an active drug in testicular cancer with a more favourable spectrum of side effects. In a randomized trial, the German Testicular Cancer Study Group compared a combination regimen of carboplatin, etoposide and bleomycin (CEB) to standard cisplatin, etoposide and bleomycin (PEB) chemotherapy for patients with 'minimal-' and moderate-disease' non-seminomatous germ cell tumors, according to the Indiana University classification.

PATIENTS AND METHODS:

PEB was given for three cycles at standard doses (given days 1-5), and the CEB regimen consisted of carboplatin (target AUC of 5 mg/ml x min) on day 1, etoposide 120 mg/m2 on days 1 to 3 and bleomycin 30 mg on days 1, 8 and 15. Four cycles of CEB were given, with the omission of bleomycin in the fourth cycle. Thus, the cumulative doses of etoposide and bleomycin applied in the two treatment arms were comparable. Fifty-four patients were entered on the trial, 29 were treated with PEB and 25 with CEB chemotherapy. Patients were stratified according to disease extent (minimal versus moderate) and the degree of tumor marker elevation. Thirty-two patients (59%) belonged to the group with minimal disease and low markers.

RESULTS:

No significant difference in response to chemotherapy was seen between the two arms, with CR rates of 81% for the PEB arm and 76% for CEB treatment. However, more patients treated with CEB (32% versus 13%) have relapsed after therapy, and 4 patients (16%) have died of disease progression after CEP in contrast to 1 (3%) after PEB therapy. The first interim analysis of negative events (relapse, vital tumor at secondary resection, death from disease and therapy-associated death) showed a significantly higher rate after CEB than after PEB therapy, and the trial was terminated early. After a median follow-up of 33 months for all patients, the calculation of negative events is still significantly in favour of PEB-treated patient, particularly since three late relapses > 2 years have been observed in the CEB arm (P = 0.03).

CONCLUSION:

This randomized trial demonstrates that even with the use of adequate doses of etoposide and full-dose bleomycin, carboplatin cannot altogether replace cisplatin in patients with testicular cancer. Treatment with the PEB regimen remains the standard approach in patients with 'good-risk' non-seminomatous germ cell tumors.
