IN BRAIN CANCER, THE INTRICACY OF THE RAC AND RICS GENES, THEIR DANCE WITH THE TIAM1
There is no underdog gene or gene not fully recognized for its power than RAC-1. yet it is a pivotal gene. RAC-1 belongs to the Rho family of GTPases and therefore is a Protein kinase activators or enabling molecule. RAC-1, like any powerful gene, will get its power through its interactions. Through PAK1, it talks to Raf (Vemurafenib's target ) but it is through RICS and TIAM1 that it reaches its full metastasis potentials in virulent cancers. Of course I am not going to Hide my penchant for the Wnt and the NOTCH genes, but this RAC-1 puzzles me (to no end, they say) when it comes to Brain tumors! tell me if I am on the right track...of course you also know about this gene that help (lipid) layers to go to their exact locations in the brain, it intrigues me also...let reconvene on this soon now! We are zeroing in!
WHAT VITAMIN D GOT TO DO WITH c-MYC ANYWAY?
Yes it is true that there is a potential link between Calcitriol (the active form of Vitamin D) and the master genetic amplifier c-MYC, a bad prognosis factor in some cancers such as small cell lung cancers. And in this type of lung cancers, the expression or activation of c-MYC is one the driving forces. And it is not the only virulent cancer to borrow the power of c-MYC.
"Amplification and expression of the c-myc oncogene in human lung cancer cell lines
NCI-Navy Medical Oncology Branch, National Cancer Institute, National Institutes of Health, and Naval Hospital, Bethesda, Maryland 20814, USA
Genetic changes involving the c-myc oncogene have been observed in human tumours. In particular, the c-myc gene is translocated in Burkitt's lymphoma1–3 and is amplified in the human promyelocytic leukaemia cell line...."
----------------------------------------------------------------------------------------------------
(If you happen not to find a target for therapy, call CRBCM, immediately!) today VITAMIN D is given at 50,000 IU weekly.
----------------------------------------------------------------------------------------------------
Calcitriol acts through its receptor, the Calcitriol receptor of course, will eventually interact with a Zinc finger and BTB domain-containing protein 16, encoded by the ZBTB16, a popular gene that will engage events in the epigenetic areas which include many receptors (watch out because even the Angiotensin receptor is engaged). But ultimately the RUNX and the GATA2 are also engaged. The involvement of SN3A and MDX1 however will have the most importance when it comes to c-MYC since these gene impact the Mad-Max complex. And you know what c-MYC needs to be active (association with MAX),
let Wikipedia tell you:
MAD protein is a protein that in humans is encoded by the MXD1 gene.[1][2]
MAD-MAX dimerization protein belongs to a subfamily of MAX-interacting proteins. This protein competes with MYC for binding to MAX to form a sequence-specific DNA-binding complex, acts as a transcriptional repressor (while MYC appears to function as an activator) and is a candidate tumor suppressor.[2] The MAD-MAX protein dimer may be a reference to the popular cult classic film Mad Max (1979)."wikipedia

Description of Spindel Cell Sarcoma and why inflammation and injuries can lead to spread of malignant cells
Spindle cell sarcoma
From Wikipedia, the free encyclopedia
Spindle cell sarcoma is a type of connective tissue cancer in which the cells are spindle-shaped when examined under a microscope.
The tumors generally begin in layers of connective tissue such as that
under the skin, between muscles, and surrounding organs, and will
generally start as a small lump with inflammation that grows. At first
the lump will be self-contained as the tumor exists in its stage 1
state, and will not necessarily expand beyond its encapsulated form.
However, it may develop cancerous processes that can only be detected
through microscopic examination. As such, at this level the tumor is
usually treated by excision that includes wide margins of
healthy-looking tissue, followed by thorough biopsy and additional
excision if necessary. The prognosis for a stage 1 tumor excision is
usually fairly positive, but if the tumors progress to levels 2 and 3,
prognosis is worse because tumor cells have likely spread to other
locations. These locations can either be nearby tissues or system-wide
locations that include the lungs, kidneys, and liver. In these cases
prognosis is grim and chemotherapy and radiation are the only methods of controlling the cancer.Spindle cell sarcoma can develop for a variety of reasons, including genetic predisposition but it also may be caused by a combination of other factors including injury and inflammation in patients that are already thought to be predisposed to such tumors. Spindle cells are a naturally occurring part of the body's response to injury. In response to an injury, infection, or other immune response the connective tissues will begin dividing to heal the affected area, and if the tissue is predisposed to spindle cell cancer the high cellular turnover may result in a few becoming cancerous and forming a tumor.

We are not the only ones looking into Sirtuins and how to reduce cellular stress response in the Brain:
Cellular stress response, sirtuins and UCP proteins in Alzheimer disease: role of vitagenes
Immunity & Ageing 2013, 10:41

Abstract
Alzheimer’s Disease (AD) is a neurodegenerative disorder affecting up to one third
of individuals reaching the age of 80. Different integrated responses exist in the
brain to detect oxidative stress which is controlled by several genes termed Vitagenes. Vitagenes encode for cytoprotective heat shock proteins (Hsp), as well as thioredoxin,
sirtuins and uncouple proteins (UCPs). In the present study we evaluate stress response
mechanisms in plasma and lymphocytes of AD patients, as compared to controls, in order
to provide evidence of an imbalance of oxidant/antioxidant mechanisms and oxidative
damage in AD patients and the possible protective role of vitagenes.
We found that the levels of Sirt-1 and Sirt-2 in AD lymphocytes were significantly
higher than in control subjects. Interestingly, analysis of plasma showed in AD patients
increased expression of Trx, a finding associated with reduced expression of UCP1,
as compared to control group.
This finding can open up new neuroprotective strategies, as molecules inducing this
defense mechanisms can represent a therapeutic target to minimize the deleterious
consequences associated to oxidative stress, such as in brain aging and neurodegenerative
disorders.
Too little, too late!
In a living cell, things are constantly happening, nothing is still, molecules are constantly cross talking
so to believe that lipid deposits from Arteriosclerosis is benign is foolish...the endothelial cell that is covered by this stuff is constantly under pressure and Cytokines are being produced that will come back to hunt us as we plant head in the sand! When it comes to cholesterol build up "zero tolerance " should be our norm. But we have no lipase to throw at it we have no easy solution, so we wait that the occlusion be more that 75% to attempt something...by then Cytokines have done their deeds, irreversible damage may have been done to the blood vessel wall. Could PGC 1, the master co-activator, have warned us of the real toll on our systesm? or is it the PPARy, the RAR, c-AMP? What are the true genetic biomarkers of Arteriosclerosis (to be continued)

GENE WORK INVOLVING Breast CANCER SURVIVORS
With significant progress being achieved in cancer therapy, we are finding ourself living with our sisters and few brothers who had gone through the horrific ordeal of Breast Cancer treatments and now live with this doubt on whether or not the disease is going to come back. While it is true that in most solid tumors, the 5 year survival rule could be applied, and that we can reassure victims of solid tumor disease that once you pass 5 years post treatment, your risk of recurrence is critically decreased and one can venture to call this bench mark for cure, Breast cancer remains a mysterious disease that seems to escape this general rule! Breast Cancer can return when it wants....It seems that for some reasons it can stay dormant, and wake up to disturb its victim once again. (Clue) What this is reminiscent of, is of course Viral Herpes when it first shows up as chicken Pox and goes to sleep in our nerve roots, and break out as Shingles later on in our peaceful life to disturb and affect it. (New clue, progress in HIV, it is now a chronic disease)
At gene level, nothing occurs without some genes acting out! It is time that we answer the questions that survivors need from us. The genes are there, let take the time to look at them and stop this cancer cell madness of trying to come back in our survivors. No head in the sand because we don't have an answer, but take the Bull by the Horns and see what happens! (You know what I mean!)

TRYING OUR BEST TO TALK TO THESE GENES IN BREAST CANCERS: MED1,6 and 12
With the clinical finding that Bicalutamide, a non steroidal anti-androgen, has a role in some of the luminal forms of Breast cancers, genes affecting the Hormones have quickly become the focus of intensive research. So we venture to explores some of the genes having links to Hormone. At CRBCM we are looking at DAX1 as it interacts with COPS2 and through the thyroid Hormone Receptor alpha gene will affect the MEDs which ultimately the Glucocorticoid Receptors and a slew of other critical receptors and genes (even the BRCA-1) is in the line of fire!
Now how important this observation is in triple negative breast cancer is still a matter of debates. Proof of concept work is still needed but it is a clear start, join the discussion!
" MED1 has been shown to interact with Thyroid hormone receptor alpha,[4] Androgen receptor,[5] Cyclin-dependent kinase 8,[6][7] Glucocorticoid receptor,[8][9] BRCA1,[10] Hepatocyte nuclear factor 4 alpha,[11][12] Peroxisome proliferator-activated receptor gamma,[13] PPARGC1A,[14] P53,[15][16] Estrogen receptor alpha,[7][17] TGS1[18] and Calcitriol receptor".[6][17] wikipedia
WHERE ELSE COULD THINGS BE HAPPENING BUT HERE!
THE INVOLVMENT IS THE CALCITRIOL RECEPTOR IS ANOTHER AREA OF INTEREST. THIS MED1 SEEMS LIKE A GIFT THAT KEEP ON GIVING. THE ANDROGEN RECEPTOR INVOLVEMENT IS A CRITICAL STEP SINCE IT BELONGS TO THE "WILD GENES"

Proof that target therapy has come in to change things in cancers!
1.Combining Ibrutinib with R-CHOP is not only feasible but yield 100% response in Diffuse Large cell Lymphoma.
For decades, CHOP had remained King of treatment of diffuse large cell lymphoma
Elaborate combinations of chemotherapy drugs failed to improve on CHOP, until the targeting of CD20 by Rituxan. And now with the arrival of the almighty powerful Ibrutinib, response rates seem to be overwhelming although not all seems to be complete Responses, at least not yet since analysis of data is still ongoing!

The secret of triple negative breast cancer
Common sense tells us that events happening in your women when they acquire childbearing age contribute significantly to the happening of triple negative breast cancer. The young woman has gone through infancy when events here are more related to the setting of class I HLA antigens first for self tolerance, then comes exposure to the outside world and the building of defense mechanisms. Implying development of class II HLA Antigens which we know by now are very much linked in their variations to racial disparity. Then the young woman enters puberty which brings in the reign of the Estrogen with its extensive methylation of genes dampening the Class I HLA to prepare the young lady's body to receive the foreign "body" of the potential infant. We have touched in one of our precedent writings about the effects of Estrogen on the immune system. We have extensively discussed the interaction of Interferon and TNF /TGFs on receptors of Estrogen (Activation followed by desensitization or lack thereof. The female individual with autoimmune disease will be much more affected by the surge of cytokines above. Then come the menses with their resulting Iron deficiency which prones the body to the danger of Reactive Oxidative species. But as far as genes are a concern, the most important event is the development of the breasts. It is the reign of the PROLACTINS.....
Indeed, it is Prolactins that will happen on this background of Estrogen/Cytokines effects. Don't think of Prolactin as a hormone, it is a Cytokine! Yes, it comes in to not only have a direct effect on the Janus Kinase 2 and induce the JAK-2-STAT pathways, but through its Dopamin Receptor, it will pound on the c-MET effect and exert numerous pounding on the PIK (effect include on its regulators (AGAP2) pathway....If you happen to have another genetic abnormality such as BRCA, or too much free Iron stimulating the HIF or any other failure....something wrong is bound to happen....such as ...triple negative breast cancer.....The point is, don't forget the Prolactin reign!!!

CRITICAL POTENTIAL NOTIONS IN UNDERSTANDING TRIPLE NEGATIVE BREAST CANCERS
It all makes sense that Hypoxia induced by respiratory failure in a predominantly obese population will contribute to generation of Reactive Oxidative Species and that Over eating of sugar based products will worsen the events that will lead to HIF-1 gene excitation and probable amplification, which eventually involve the VHL (justifying the correlation of clear cell Renal cancer with obesity), and eventually amplify angiogenic genes (EGFR,VEGF). This will end-up through Gerb2 connection gene, amplify the G proteins connected MAPK and could drive to a neoplastic process. When p38-MAPK is involved there appears that the process will be accompanied by a significant cytokine release leading to an associated inflammatory process. This is why anti-p38 is more looked into for its anti-inflammatory consequences rather than anti-neoplastic processes. For this inflammatory process to be successful, stimulation of the CREB must be suppressed, which it is in hypoxia. The level of Cyclic-AMP is also dampened as a result.
In the epigenic zone, amplification of the MAPK will ultimately amplify the MIFT (MIFT was first described under these conditions of amplified MAPK) with consequences that lead to dampening of Androgen activity if the MIFT interacts with PATZ1.
If MIFT interaction is mediated via PIAS3 binding,, ER will be next to be knocked out
Wikipedia: "This interaction is mediated via PIAS3 binding to the STAT3 DNA binding domain. Hence, STAT3 transcriptional activity is inhibited by the physical prevention of its binding to target genes. Subsequently, PIAS3 was also found to be a regulator protein of other key transcription factors, including MITF,[6] NFκB,[7] SMAD [8] and estrogen receptor.[9] PIAS3 protein also functions as a SUMO (small ubiquitin-like modifier)-E3 ligase"
Pretty soon, you have yourself a triple negative breast cancer!!!
(leading to the question is IL6 elevated in this disease?
MIFT involvement with TFE3 will engage HMGA-2 and prop the metastatic propensity in this disease (triple negative breast cancer).
The involvement of MIFT is obligatory since it will unlock the chromatin to allow access to nuclear material by chromatin modulation

Be careful when targeting these genes, some of them are "wild genes", meaning that they could be leading to the activation of many more genes. As we discussed, handle these with care because you will not be able to control their side effects....Other genes are just critical to so many functions ie. the ELK-1 gene. You may use it for pro-apotosis, but it is a gene that, once knocked down, can lead to Alzheimer dementia and many more neurologic disturbances. So read carefully before targeting these genes. Some could lead to seizures or sudden Neurologic dysfunction, so pick and choose carefully and be prepared to handle Neurologic or cardiac complications...and always start with Phase I as per standard....Indeed you are in the belly of the beast, tread carefully!

Deep in the belly of the beast, ARE HIDDEN NICE THERAPEUTIC TARGETS!
As we examine deeper for possible targets for therapy, we are not swayed by media or political pressures which are mounting, but we look at real facts that are scientific and based on real data and deep studies of pathways: 6 targets come out either because they are at the intersection of pathways or because they are critical, obligatory steps to either DNA proliferation or cytokine production. They are: JNK, P38, ERK, SRF, c-fos, CRE, ELK-1, NLK, oh hell did I say 6...my mistake but depending on the neoplasia under consideration, the list can be prolonged.
It will include: Sap1a, NFAT, JUN-D,atf2,p53,GADD53,PRAK,MAX,HSP27/72,PP3C,
GOOD HUNTING!
SNIFF THE BEST AND TAKE YOUR PICK! AND GUESS WHAT: THE DEVIL IS NOT VERY FAR (I MEAN THE DVL GENE) !

Interesting genetic concepts
* Immediately post brain trauma, Blocking DISC1 --- GSK-3 INTERACTION
could affect post traumatic brain disorder. I wonder if early administration of Cyclosporin can have this effect by affecting the NFAT pathway?
* In small cell, I wonder if the YWHAE and CDK5 should be the focus of our attention? Definitively looking into the Noonan disease gene since it induces malformation.
Inhibitor of the CDK5 should be the focus since the experience with the Melanoma has brought light on these inhibitors (p16/CDK2A/CDK4)!
* Could Disturbance of DISC1 explain post Radiation syndrome or "chemo-Brain"?
* Could Cyclosporin and various interventions decrease post Radiation encephalopathy?
*Is there a surge in peripheral blood cytokines post Radiation as experienced in Traumatic brain injury? And what cytokine is being observed?

CELLULAR PLAY
I strongly believe the cell has multiple plays to hide from us its intrinsic play when it comes to neoplastic process. I believe we have the cards and each of us has a hand of cards to play with. I believe we have before us confused facts, we need just to make the next step. yes we have the basic facts, we just need to read them correctly. We know all the genes, and know most of their main roles. And we have solid leads...
We know that stress leads to Gastric cancer, and we know the NF-kB is wild at play but so far our examination has been incomplete, and clearly we would benefit by looking at this pathway deliberately and completely since that approach would yield various culprit genes and potential targets to treat the ailment.
We know that in triple negative breast cancer the NF-kB must be implicated with disruption at hormone receptors. BRCA and its full pathways of co-factors and downstream molecules (ie.BABAM-1, HTATIP and ETV-6). And now the role of Androgen in luminal form of this cancer, the WISP3 in inflammatory Breast. All these messages have not resounded in our head enough to excite us to cross the bridge...
We have the "wild genes" CRE,Gerb,Lyn,MyH or MyB, Flyn, Ep300, AR, etc.. Basically we know when things reach here, everything goes!
We know full differentiation requires the NOTCH, and MEK is the door to de-diferentiation (under the NOTCH control of the MAPK through the ADAMS10). We know Ubiquitination is also under NOTCH influence...But we don't still use fully the Info!
Using the "master integrator" to its full potential too in cancer prevention to dampen Reactive Oxide species and reduce EGFR positive lung cancer in non smokers would be a significant new approach.
All this is on the desk at CRBCM as we start 2014. Wish us luck, the fight is still ahead.

Looking at an earlier find in Melanoma!
For the longest time in Melanoma therapy, only DTIC and interferon were cited in Melanoma therapy. Interferon was given in adjuvant setting Mostly and DTIC in Metastatic diseases from Melanoma. Despite our understanding of the working of Interferon, there no clear biomarker that would predict which melanoma would be more snsitive to Interferon. Therefore integration of Interferon into new combinations with new Target therapies such as Ipilimumab and Vemurafenib, remains a hot topic of investigation.
Interferons can act on tumor cell through the direct JAK-STAT pathway, but for some other reasons, go through the ISGF/GAS/PE-1/p91 pathways. The interferon can recruit stimulation of the IRF pathways as well as activating the MHC class I to immunologically block progression in Melanoma. How this will impact the effects of newly found pathways of Ipilimumab and Vemurafenib is anybody guess and a matter of current trials. It appears that we now have to play catch-up, since earlier investigations to define predictive biomarkers for interferon/DTIC responses were not timely completed. Turning and returning a old stone needs once again to be completed!

BURNING QUESTIONS!
1. OH! let me come out and say it!
Don't you believe by now that there is this suspicion that interfering with Iron Receptors could decrease the rate of metastatic disease to the lungs? Would it be grand to actually prove you could slow down Hepatoma or breast cancers from moving to the lungs by sending an Antibody against Iron receptor? Let's look closer into the data! and reconvene in the coming year to get an update! At the CRBCM, we are working overtime!
2. Could gene interference with EP300 boost anti-VEGF Medication? It is after all a co-Activator of HIF-1, isn't it?
3. Cataract prevention: what is the standing of the CRYAB gene? What about the RPGRIP-1 gene in retinal damage?

DANCING WITH A GIANT NAMED: "THE SMALL HETERODIMER PARTNER"
There are 25000 genes in human cell approximately or give and/or take they say!
and only 20% are active at one given time they estimate. But make no mistake about it, the rule of "company you keep" has not been as strong at play as it has in genes! The Small Heterodimer PARTNER (SHP) really in the thick of it. See it plays with one of the gene involved with a tissue which, once cancerous, lead to incurable cancer. SHP interacts with non other than Hepatocyte nuclear factor 4 alpha (HNF4A). And through this gene, it will reach a "wild gene" called "CREB-binding" which affects in its dealing to close to 50 genes ( Hell! all genes since it it is involved in the "breathing" of the cell!) This small Heterodimer Partner is a misnomer, it is a GREAT Partner important in the function of all major Hormone from Androgen to Estrogen! Touch this one, and you will feel the vibe! If you know What I imply...

ACTIVITY AT CRBCM
ONE COULD NOT STAND THE BEAUTY OF OUR POSTER, WE CAME BACK WITHOUT OUR POSTER ON TRAUMATIC BRAIN INJURY PROJECT, STOLEN AT THE CONFERENCE.
I GUESS IT IMPRESSED A HECK OUT OF SOMEONE! STOLEN POSTER, THAT'S JUST IMPRESSIVE AN ACHIEVEMENT FOR ANY POSTER! LUCKILY, WE STILL HAVE IT ON A MEMORY CHIP!

WHO CARES ABOUT THE TISSUE OF ORIGIN WHEN YOU HAVE THE GENETIC PROFILE OF CANCER?
TIVANTINIB, anti-c-MET
OBINUTUZUMAB, AN ANTI-CD20, FDA APPROVED IN CLL
NINTEDANIB, anti-EGFR
PONATINIB, NOW "DEFUNCT" BECAUSE OF THROMBOTIC COMPLICATIONS
========================================
WHO CARES ABOUT THE ORIGIN OF THE CANCER WHEN YOU KNOW THE DRIVER MUTATIONS?
When you treat triple negative Breast cancer luminal type with Bicalutamide, when you treat Angiosarcoma in the liver with Avastin, even Melanoma with Yervoy, lung cancer with Crizotinib, who really cares about the tissue of origin? We are now at the stage where chemotherapy will need to be dictated not by the Oncologist, but by a Central Pathology department giving us the gene profile for each cancer diagnosed in town!
The Europeans are now planning this move as we heard from the grapevine! are we ready?...it will be cost effective and reportedly better for our patient outcome as suggested in recent studies (for the hard believers!). "New Paradigm" = Not the tissue of origin, but the genes! Medicine is a shifting field and new technology is rolling in...I got to go to that Nano meeting planned in March...Europe here we come!

Creating a new path like the CRBCM!
Each time we turn around, people rush to discourage CRBCM that this and that has been studied and therefore there is no point to revisit the question. It is a weakness to believe that when it comes to cancer biology, revisiting a topic at molecular level always unveil an interesting aspect that had remain hidden or overlooked. Surprises are everywhere, you just have to keep your eyes open and remain suspicious of the evident...The Retinoic Acid Receptor has been known for long time, but the story of ATRA in Promyelocytic Leukemia does not date that long. As a matter off fact the story of Targeting therapy is not that old. It took a second look with new technologies to uncover new aspect of the same story. For a sole Researcher, going it your way may pay big. Shackled in large institutions, you have to follow the direction of the chief! But on your own, just pick up and go, surprises are still awaiting! There are 25000 genes, each with its habits, reactions and adaptations that are not fully uncovered. To believe otherwise is foolish, work hard and keep at it! The CRBCM is on that path...we believe is the future! Passion will take us there!
I was just reading about Lung cancer and what pathological Biomarkers have entered standard therapy (EGFR, ALK, ROS-1,etc...). These are for therapy decision, is that means our patients have stopped their need to know about for early diagnosis, no! Is that means we don't want to know about prognosis? No...if you work in this area, just keep on plugging along, until those who doubt come to recognize they are short sighted...things are awaiting your discovery everywhere your mind and heart take you...just keep at it!

ACTIVITY AT CRBCM: BIG DAY TODAY ONCE AGAIN
We are presenting our TBI project at the scrutiny of the staff at the University Medical Center and Faculties at both Texas Tech.and the Paul L.Foster School of Medicine. We have 15 minutes to convince our audience that Butein an Activator of Sirtuins could limit post traumatic events at gene level that broaden brain lesions. The task at end is huge because it does not only involve the trauma but extensive genes from regulation of Calcium store in the ER to the involvement of Maf, ICER, p21SFT, GATA, EGR, to OCT, HNF3,IRF4 to the NEF2.
Also DR Ray Lundy has officially announced his Retirement, and Greater East will be taking over his operation, we will be double busy!
The preliminary results on the 5 lung cancer tissues is now available for review with DR Jangh.
CRBCM, advancing in a resisting world but our fight is just!
