We have discussed that chemical, traumatic and sometimes burns from caustic solutions that people ingest unfortunately, that will stimulate the cellular membrane receptors which in turn will stimulate RAS, which in turn will amplify PI3K, MAP Kinase and RAL/CDC42. But remember these are stressful stimulations, so instead of the standard MAPK, the stimulation is imposing on RAS to awake the NFkB pathway, the c_JUN and at nuclear level the FOS which results in inflammatory proteins stimulation including cyclin production or liberation from membranes with extracellular release of Metalloproteases. Cyclins combining to CDCs will exacerbate cell divisions and proliferation, growth factors will promote cell growth, there is an associated ligase proliferation that will impact P53 (through MDM2) and c-MYC, NOTCH, and even c_JUN itself through FBW7/hCDC4. This is how the proteasomes come into play!
By now you now
1. that amplification of c-MYC exacerbate proliferation by allowing progression of cells int S-phase and bolster DNA replication, imparting bad prognosis to cancer cells.
(nature is kind and gies you a chance to affect here by freeing RB1 and increasing FBW7. Oh! also find MYCN and the p isoform to q for answers!)
2 Rb1 does sequester E2F. you can look at it both ways. that E2F stabilize Rb1 instead, whichever way one stop the other for acting! Remember E2F activates CPP32 which increase APOPTOSIS! (DRUM UP THOSE TARGET THERAPY!)
3.REMEMBER RAS NEEDS A FATTY ACID MOIETY TO STAY AT THE MEMBRANE FOR ITS ACTIVITY (THIS IS ITS SO CALLED POST-TRANSLATIONAL MODIFICATION) BY THIS PHRENYLATION IS IMPAIRED BY THE FARNESYL TRANSFERASE INHIBITOR
(ie. TIPIFARNIB) THAT WE DO NOT USE ENOUGH I FEEL! ALTHOUGH I AGREE THAT SIDE EFFECTS MAY BE PROHIBITIVE GIVEN THE EXTENT OF WHICH NORMAL CELLS WILL ALSO BE COMPROMISED. BUT IT GOES TO THE FACT THAT WE NEED TO FURTHER TWEAK THIS MODALITY TO MAKE IT USABLE IN CANCERS!
ANTI-MEK HAVE DEMONSTRATED USE IN KRAS MUTATION CANCERS! MAY BE ESOPHAGEAL CANCERS WILL BENEFIT HERE!
4Role of combining Velcade and Carfilzomib in Esophageal cancer to see if c-Myc can be affected? Will it increase the right Ligand (FBW7)?

ESOPHAGEAL CANCER
Whether you consider Adenocarcinoma or squamous cell cancer of the Esophagus, you will have to come to the realization that you are looking at the result of a chronic irritation on Esophageal mucosa. The irritation in chemical when it comes to Gastric Acid for the Adenocarcinoma of the Gastro-esophageal (G-E) junction, or it could be traumatic as rough stuffs are swallowed, this include chemicals and alcohols (these days you cannot imagine what people put in their mouth-live scorpions even!) So chemical and rough stuff induce a squamous cell cancer in the upper Esophagus while Gastric reflux lead to an An Adenocarcinoma. However you get their the insult will be register at cell level through our membrane receptors which are trans-membrane structures. In some of these receptors, there is portion facing the cytoplasm called RTK (receptor Tyrosine Kinase) which dimerize on stimulation and/or autophosphorylate, , and This commotion attracts the Sons of the Sevenless which lights up the RAS by bringing in the Erb2 to attach to he RTK. My sons of the Sevenless gives off a Guanine that activates RAS. And here we go with Ras and related molecule amplifications. RAS is known to amplify 3 pathways
1. the MAP Kinase pathways which will go on to stimulate formation of transcription factors that will make proteins structures to deal with the situation, or tell the cell what directions things will go or manage the challenge globally!
2. the RAL/CDC42 pathways that send message to the Cytoskeleton (the nervous system at cell level)
we are talking about stand up and fight Vs flight management. This system by following the Actininic cytoskeleton through the mambrane and the Reticulum endothelium (RE) reaches in a flash the Nucleus (that's where RE goes ) We are talking in a flash the cell is informed at Histone level and is ready to process the info and react!
3. The PI3K pathways which readies the cellular response which include needed protein response but also include initiating programmed death if that is an appropriate response! (The FOX (o) is hidden behind the MTOR down this pathway! FOXO hold the key to survival of the cell!
REMEMBER RAS CAN NOT GO WILD EXCITING THESE PATHWAYS, IT IS TEMPERED BY NF1 WHICH BELONG TO THE FAMILY OF GAP, GIVING A GAP (BREAK) OF FUNCTION TO RAS . IF THERE IS NO GAP, AND RAS GOES WILD, YOU GOT YOURSELF A NEUROFIBROMATOSIS ON YOUR HAND TO DEAL WITH! IT IS WORTH NOTING THAT GAP CAN BE DECREASED RELATIVELY TO GEF. THAT IS TO MUCH GEF IS TRANSLATED AS A DECREASED GAP AS GEF TAKES CONTROL. SO ONE WAY TO AFFECT RAS IS TO INCREASE GEF (THE BALANCE WILL BE BROKEN TO THE DISADVANTAGE OF GAP) AND RAS WILL BE HYPERSTIMULATED! (TARGET THERAPY)

BREAKING NEWS: New CPRIT Oversight Committee Proposals Kill Commercialization Arm Of Organization
Posted Friday , March 15,2013 from www.statesman.com › Business
A set of newly-published proposals put forth by the CPRIT
oversight committee strips out the Chief Commercialization Officer and
related committees, suggesting that the cancer fighting organization
will no longer be permitted to attract new biotech companies into Texas.A sweeping set of new proposals posted today on the Texas Register by the CPRIT oversight committee seeks to make wide-ranging changes to the cancer research funding organization by effectively eliminating its role in using Texas taxpayer dollars to foster biotech startups in the state, as well as attract major biotech corporations to relocate. The new statues, which propose changes to virtually every aspect of the organization, appears to replace the entire commercialization arm with new compliance and oversight officers, as represented in Section 703.2 of the document:
Section 703.2 adds the definitions for “chief product development officer”, “compliance officer”, “product development review council”, and “product development prospects.” The section proposes to delete references to the “chief commercialization officer”, the “commercialization review council”, and “commercial prospects”. The section also clarifies the definition of “cancer research” to include research into the prevention of cancer.Deleting references to the “chief commercialization officer,” “commercialization review council,” and “commercial prospects,” suggests that CPRIT’s new organizational structure will not include its once robust operations to attract private biotech companies into the state. These changes would lay to waste incubator programs designed to help foster new start-ups within Texas, as well as significant relocations of biotech operations.
Conversely, the addition of roles such as “chief product development officer,” “product development review council,” and “product development prospects” would suggest that the commercialization arm will now be more limited in scope, and focus on smaller, in-state product development projects, rather than attracting entire business and operations into the state. The new document describes the role of chief product development officer as: “. . . the individual employed by the Institute to oversee the review and evaluation of grant applications for the development of drugs, biological, diagnostics, or devices arising from cancer research and prevention activities.”
Similarly, the designation of product development prospects is described as: “the potential for development of products, services, or infrastructure to support cancer research efforts, including but not limited to pre-clinical, clinical, manufacturing, and scale up activities.”
It is particularly interesting that this section juxtaposes the deletion of CPRIT’s commercialization arm with the addition of a compliance officer — a detail that only further suggests that these proposals constitute a sea change in the scope and direction that CPRIT will take in the foreseeable future, should these proposals be passed by the Texas legislature.

HOLD ON TO THESE THOUGHTS
==========================
1.
"Multiplex Testing in cancer may alleviate cost issue, testing fatigue, and reduce Histology discrepancies"
(Antoinettte J. WozniaK )
I agree that by checking several genetic markers at once, one will reduce cost. We know it cost less to do a package than individual. the experience with Complete Metabolic panels should reproduced at Biomarkers'level.
And yes I looked at the pathologist as he was passing by, I noted he tried to avoid me because each time we meet I always ask him for another biomarker to test. He is really tired of testing. So the statement must be true and the cost rising on each individual patient!
Histology discrepancies reduced? hmmmm!
This one I need to scratch my head a bit! Is that means test everybody independent of histology? Is that wise (outside a clinical trial?) let's think about this! well tell me what you think!
2. "Biomarkers for Dummies"
I don't believe there is such a book! That's it. How can this be...? Can you really be a dummy if you understand what is a Biomarker! I guess there is a trick to all this that is escaping Me!
3. I get it, don't get to excited trying to test everybody! These are the rates of positive test in lung cancers:
-ROS-1 positive in 1.5 % of lung cancers
-ALK positive in 5%
-RET positive in 2%
-EGFR positive in 18%
-HER-2 positive in 2%
-BRAF positive in 3%
-MET positive in 3%
The total is 35% which is meaningful only globally and a waste of time if you go one by one. NOW I AGREE THESE SHOULD COME AS A PANEL!

S100A4, AN IMPORTANT TARGET FOR SURE! LOCATED AT 1q21
The importance of a molecule in the body is determined
by its chemical properties, the pathogenesis of the disease in which it is
participating or how critical a function it is performing in the cascade
of a pathway. The importance of a gene is determined by its
product's shape and function which is sometimes defined by atoms hanging
at its periphery, ready for business of attracting other electrons or
ions. It is also determined by genes in a linkage relationship at the
chromosome level. This last point is important to be clarified by
researchers who have the tools to explore the coexistence of genes on an
arm of a specific chromosome. And a lot of research forgets to look at
that aspect of the problem gene. (don't forget "q" most of the time
portends for worse prognosis than "p" , that is it may induce a malignant
phenotype. In fact, co-expression of homologue "p" will mitigate the
phenotype. And the homologue gene is on a p arm and on a different
numbered chromosome)
By now you also know that cell life is directed in one direction at a time frequently. Cells are under function performance, differentiation, proliferation or neoplastic transformation. Neoplastic cells are in concert with surrounding cells from which it avoids to be in conflict with to escape detection. Neoplastic Cells will be soon stressed because of their increased needs and through the c-JUN -FOS will increase a Tumor Growth factor liberated from the cellular membrane with concomittent release of Metalloproteases in the extracellular membrane through flippase-floppase activity. The Metalloprotease goes out, the Growth factor goes in.
IT WOULD BE GOOD TO KNOW WHICH METALLOPROTEASE IS SPECIFICALLY LINKED TO WHICH PROTEIN IN ORDER TO KNOW WHAT IS GOING ON INSIDE THE CELL JUNK BY DETERMINING WHICH OF THE METALLOPROTEASE FAMILY MEMBER IS IN THE EXTRACELLULAR SPACE OR BLOOD! NICE LITTLE PROJECT RIGHT THERE. "WHICH TYPE OF METALLOPROTEASE FOR WHICH CANCER" I BET, BRAIN TUMOR WILL RELEASE A DIFFERENT METALLOPROTEASE THAN OVARIAN CANCER. BECAUSE THE GROWTH HORMONE RELEASED IN THE CELL WILL BE DIFFERENT.
By now you also know that in certain proliferative processes, there is an increased aspect of only 1 or 2 functions. In Leukemias, for example, it is amplification of a certain Core binding complex which attaches certain molecules with specific functions. And the cell follows the cascade of functions to go in a certain cell life trend. Some of these proteins are gene regulators. In fact, Leukemia would be better controlled if we just determined the proteins on CBF and the regulators that are promoted in the cell. ANOTHER EASY PROJECT : THE PATTERNS OF GENE REGULATORS IN A SPECIFIC LEUKEMIA (BY WETERN OR SOUTHERN BLOT).
One of those regulators is the S100A4, a potent regulator which not only is at the differentiation, meaning when mutated or amplified it will create phenotypic havoc for sure. It is handling Calcium, therefore will affect some Microtubules (good or bad for Taxanes?): Time to find out more! Read these articles!

- High expression of S100A4 in cytoplasm at the advancing front of stage C colonic tumours indicates a poor prognosis.
- The S100A4 protein, mostly studied in cancer, is overexpressed in the damaged human and rodent brain and released from stressed astrocytes.
- we show for the first time the intratumoral knock down of S100A4 via systemic application of S100A4shRNA plasmid DNA, restricts metastasis formation in a xenografted mouse model of colorectal cancer.
- SRX forms a complex with S100A4 (and has stronger affinity for S-glutathionylated S100A4), regulates its activity, and mediates redox regulation of the interaction of S100A4 with nonmuscle myosin heavy chain II-A.
- S100A4 and its downstream factors play important roles in pancreatic cancer invasion, and silencing A100A4 can significantly contain the invasiveness of pancreatic cancer.
- HBXIP up-regulates S100A4 through activating S100A4 promoter involving STAT4 and inducing PTEN/PI3K/AKT signaling to promote growth and migration of breast cancer cells.
- S100A4 and VEGF mRNA levels were up-regulated in clear cell renal cell carcinoma (CCRCC), tissue compared with control; upregulated tumour S100A4 and VEGF mRNA levels were independent risk factors for the presence of invasion and/or metastasis
- High S100A4 is associated with ovarian cancer invasiveness.
- FSP1 localized to podocytes in focal segmental glomerulosclerosis & minimal change disease. The number of FSP1(+) podocytes per glomerular profile was higher in patients with FSGS than in MCD. There was a corresponding difference in FSP1 mRNA levels.
- Asymmetric mode of Ca-S100A4 interaction with nonmuscle myosin IIA generates nanomolar affinity required for filament remodeling in epithelial carcinoma cells.

uncoupling of G-proteins from receptors; topoisomerases; cellular folate
transport; and steroidogenesis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)'"
LOX Lysyl-Oxidase
This gene found in gastric and bladder cancer is prognostic. Its amplification allows the cell to deal with austere conditions in Metastatic conditions. It seems to be amplifying under the impetus of HIF (Hypoxia induced factor). Its amplification appears more reactive than driving the resulting dowstream reaction.It can affect the structure of laminin and collagen through its formation of Aldehyde.
It can push proliferation by acting as a co-factor at nuclear level.
It can affect AKT (Protein Kinase B).
Recently, a study in Sarcoma using a Doxorubicin isoform was set in motion. Expression of LOX should be included in the analysis since Hypoxia was a component of the treatment.
LOX would not be a principal target in a treatment strategy since it addresses mostly metastasis, it either an adjunct treatment, or will have a role in Maintenance therapy.

A few Genes on Bladder Cancer
MUC1: Mucinous cancers are known to be dangerous because by the time they are diagnosed, the extent is a little more then first thought. Mucin is used by cancer cells to hide from immune detection it is believed. MUC1 interacts with GrB 2 which affects a multitudes of other genes and transcription factors.Through YES1, it interacts with JAK2. Action through JAK2 may have been why Epogen was prohibited for use in the Curable cancer setting. JAK2 sensitizes cancer to Epogen, and to other growth factors!

AZGP1 is a tumor suppressor in pancreatic cancer inducing mesenchymal-to-epithelial transdifferentiation by inhibiting TGF-β-mediated ERK signaling
Abstract
Epithelial-to-mesenchymal transdifferentiation (EMT) mediated by transforming growth factor-β (TGF-β) signaling leads to aggressive cancer progression. In this study, we identified zinc-α2-glycoprotein (AZGP1, ZAG) as a tumor suppressor in pancreatic ductal adenocarcinoma whose expression is lost due to histone deacetylation."It is associated with FAT/cahchexic losses in these patients

Hypothesis of small cell cancer pathogenesis
Hypothesis of small cell cancer pathogenesis
It seems that stimulation from smoking and stress acting through the FOS /c-JUNK will hit at nuclear level, genes of differentiation such FHIT,( The gene encompasses the common fragile site FRA3B on chromosome 3, where carcinogen-induced damage can lead to translocations and aberrant transcripts of this gene. In fact, aberrant transcripts from this gene have been found in about half of all esophageal, stomach, and colon carcinomas.
It also known as human accelerated region 10.) (wikipedia)
FHIT will in turn affect UBE2I, the SUMO-conjugating enzyme altering this way ubiquitination
But UBE1I also affect a Myriad of important genes that will start and amplify the neoplastic process:
UBE2I has been shown to interact with WT1,[3] TOP1,[4] RAD51,[5][6] Activating transcription factor 2,[7] PIAS1,[8][9][10] SALL1,[11] FHIT,[12] RANBP2,[13][14] Protein inhibitor of activated STAT2,[8][15] DNMT3A,[16] DNMT3B,[17] Small ubiquitin-related modifier 1,[6][13][18][19] SAE2,[13][20] RANGAP1,[13][18][20] Death associated protein 6,[20][21] Androgen receptor,[22] ETS1,[23] IPO13,[24] TCF3,[25] TNFRSF1A,[26] DACH1,[15][27] P53,[6][19][28][29] BLMH,[30] MAP3K1[26] and Microphthalmia-associated transcription factor.[31] (wikipedia)

Top 1 and Rad1: these affects BRCA and other genes of DNA repair including P53. The neoplastic process wants tolerance of gene abnormalities in neoplastic cells. Methylation of FHIT is critical for cancer to mature!

GENES HYPERMETHYLATED TO FAVOR DEDIFFERENTIATION, AND NEOPLASTIC TRANSFORMATION IN LUNG CANCERS
RESEARCHERS SUGGEST THE FOLLOWING GENE AS TARGET FOR HYPERMETHYLATION: 1. DAPK
Death-associated protein kinase 1 is an enzyme that in humans is encoded by the DAPK1 gene.[1]
Death-associated protein kinase 1 is a positive mediator of gamma-interferon induced programmed cell death. DAPK1 encodes a structurally unique 160-kD calmodulin dependent serine-threonine kinase that carries 8 ankyrin repeats and 2 putative P-loop consensus sites. It is a tumor suppressor candidate.[2]
In melanocytic cells DAPK1 gene expression may be regulated by MITF.[3]"
AND YOU KNOW THAT ANYONE WHO WANTS TO LIVE WILL SILENCE THIS GENE. KILLING INTERFERON EFFECT IN LUNG CANCER DESPITE STRESS INDUCTION ROLE IN THE PATHOGENESIS OF LUNG CANCERS.
-------------------------------------------------------------------THIS GENE WAS DISCUSSED IN OTHER BLOG NOTE---------
2. GSTP1
Glutathione S-transferase P is an enzyme that in humans is encoded by the GSTP1 gene.[1][2]
Glutathione S-transferases (GSTs) are a family of enzymes that play an important role in detoxification by catalyzing the conjugation of many hydrophobic and electrophilic compounds with reduced glutathione. Based on their biochemical, immunologic, and structural properties, the soluble GSTs are categorized into 4 main classes: alpha, mu, pi, and theta. The glutathione S-transferase pi gene (GSTP1) is a polymorphic gene encoding active, functionally different GSTP1 variant proteins that are thought to function in xenobiotic metabolism and play a role in susceptibility to cancer, and other diseases.[3]
GSTP1 has been shown to interact with Fanconi anemia, complementation group C[4][5] and MAPK8.[6]"
METHYLATION HERE IS TO PERPETUATE THE ACTION OF CAUSING FACTORS. IT IS BAD FOR PATIENTS TO CONTINUE SMOKING ON TREATMENT. THIS IS AN EARLY EVENT IN TUMOR NEOPLASIA TRANSFORMATION.

IN SMALL CELL LUNG CANCER ONE CANNOT OVER-EMPHASIZE THE ROLE OF SOX2 GENE!
IT IS A GENE THAT LEADS TO ORGAN DEVELOPMENT (EYES), ANOPHTHALMIA SYNDROME, MICROPHTHALMIA, SEPTO-OPTIC DYSPLASIA

IF IT INVOLVES ORGAN DEVELOPMENT, REMEMBER THALIDOMID AND ANTI-ANGIOGENIC DRUGS EFFECT!
SRY (sex determining region Y)-box 2, also known as SOX2, is a transcription factor that is essential for maintaining self-renewal, or pluripotency, of undifferentiated embryonic stem cells.
Sox2 is a member of the Sox family of transcription factors, which have
been shown to play key roles in many stages of mammalian development.
This protein family shares highly conserved DNA binding domains known as
HMG (High-mobility group)
box domains containing approximately 80 amino acids. Sox2 has a
critical role in maintenance of embryonic and neural stem cells and
holds great promise in research involving induced pluripotency, an
emerging and very promising field of regenerative medicine.[1]
-----------------------------------------------
Its association with NM1 increase its amplification.
Here you find the role of JAK-STAT pathway as prominent in SCLC.
You also find understand why this propensity to CNS metastasis
They did not say anything about MEK, the door to dedifferentiation!
It forms a complex with OCT4
and interacts with YES1, FGF4, UTF1 and ZFP206 (By similarity)
and with . Downstream
--------------------------------------------------------------This gene lies within an intron of another gene called SOX2 overlapping transcript (SOX2OT). The importance of SOX2 and OCT4 as regulators of pluripotency has been dramatically illustrated by the demonstration that these factors together with c-Myc and Klf4 or Nanog and LIN28 can induce the dedifferentiation of somatic cells into induced pluripotent stem cells (iPS) with many of the features of embryonic stem cells, Takahashi, K. and Yamanaka, S. (2006); Wernig, M. et al. (2007) and Yu, J. et al. (2007).
Nanog is also a very important early regulator of pluripotency. Together SOX2, OCT4 and Nanog co-regulate a growing list of downstream target genes. Target genes include YES1, FGF4, UTF1, Fbx15, Zic3 and ZFP206, but this is only a sampling of the hundreds of genes that are involved. The targets of SOX2, OCT4 and Nanog have recently been identified using time course microarray and genome-wide immunoprecipition data, Sharov, A.A, et al. (2008).
Loss of function SOX2 mutations have been linked to the rare disease microphthalmia syndrome type 3, small eye, (MCOPS3), Ragge NK, et al. (2005); Verma, A.S, and Fitzpatrick, D.R. (2007.)
-----------------------------------------------------------------------------------------------
(Chen et al.) SOX2 contributes to the tumorigenesis of lung cancer cells and can be used as a diagnostic probe. In addition, obviously higher expression of oncogenes c-MYC, WNT1, WNT2, and NOTCH1, AND YOU KNOW THAT IF YOU TOUCH THE WNT , YOU FIGHT VIGOROUSLY BREAST CANCER! OPENING UP SOX2 AS A MAJOR TARGET IN BREAST AND LUNG CANCERS!

IF YOU DO NOT FIND A TARGET THERAPY, DREAM AGAIN!

Function and expression in pluripotency
LIF (Leukemia inhibitory factor) signaling, which maintains pluripotency in mouse embryonic stem cells, activates Sox2 downstream of the JAK-STAT signaling pathway and subsequent activation of Klf4 (a member of the family of Kruppel-like factors). Oct-4, Sox2 and Nanog positively regulate transcription of all pluripotency circuitry proteins in the LIF pathway.[2]In an experiment involving mouse embryonic stem cells, it was discovered that Sox2 in conjunction with Oct4, c-Myc and Klf4 were sufficient for producing induced pluripotent stem cells.[6] The discovery that expression of only four transcription factors was necessary to induce pluripotency allowed future regenerative medicine research to be conducted considering minor manipulations.-----------------------------------------------
