FDA APPROVED POMALIDOMIDE
MUTATION IN "p" IN A CHROMOSOME IS GOOD FOR YOU!
To further confirm that "p" is better that "q", I went back to see what is the mutation in a curable cancer and germ cell tumors or testicular cancer. And guess what? It is not 12q that is abnormal in testicular cancer, IT IS INDEED 12p that is involved in the Malignant transformation.
CCND2 is at 12p13, but also SOX5, JAW1, and KRAS is at 12p11.2-12.1
You know angry corresponding family members are located on other chromosomes, but not amplified in Testicular cancer and would confer resistance to therapy. In fact it would be interesting to see if they are amplified in refractory cases for proof of concept!
The association with endoreduplication (Multiple ploidies) is another good thing to look into further as it relates (or not) to 12p Mutation!
Certainly the response to chemotherapy alone is an intriguing phenomena by itself and should open up cues to look for in other cancers! I believe it is in the "p" and in the "ploidy" thing or tendency to multiply that is where the cancer vulnerability is squarely located!

Cellular Variations/language *New German study finds Kras stimulation in Pancreatic cancer is not the same as Kras stimulation in the lung and therefore PI3K expression will not have same implications
Selective Requirement of PI3K/PDK1 Signaling for Kras Oncogene-Driven Pancreatic Cell Plasticity and Cancer
Stefan Eser, Nina Reiff, et al.
Read it. It tells you that not only the implications of a stimulation of one molecule change with the tissue because of tissue specific genetic silencing , but also changes can occur on different RAS family member (NRas or Hras) leading to different meaning in terms of consequence for the cell.
Another discrimination level is that many types of stimulation can induce the same pathway. C-JUN can be induced by radiation, chemical, hypoxia or infection. Any thing that is considered stressful, including lack of extracellular stimulation. This last point is very important in the Central nervous system where pre-synaptic stimulation is critical for post synaptic neurons. Lack of stimulation induces an inflammatory process in both the neuron and the glial cell. In the glial cell, the myelin sheath is scarily attacked or no longer formed.
The duplicity phenomena occurs particularly at the cellular membrane where many receptors would be stimulated by several stimulants and vice versa (many stimulants for same receptor). Only the cell and its tissue type know what to give out!
*New study concurs that mammogram should be done every 2 years and after 50 years of age. That only those women with dense breasts should start at 40 years of age and annually. The controversy dance is fueled once again and I don't blame anyone! We have seen cases of course which did not fit these prescription. Why change things that work.

PANCREATIC CANCER GENE (CONTINUED)
1' KRT20: keratin related gene, most likely of an early expression in neoplastic transformation
more predictive and diagnostic than of less therapeutic potential.
2-TEM 7: The blood vessels of Tumors seems to have an exclusive marker called Tumor Endothelial Marker or TEM. Target therapy directed at this stuff may lead tumor to anoxic death by closing these vessels, at least that the wish of researchers, will follow their efforts!
Certainly this used as serologic marker or radiologically, can locate metastatic lesions.
3-MAP2K4" direct activator of the MAPK/c-JUNK through MAP8& 14. (Not the standard MAPK1)
but it also interact with an anchor called Filamin Though FLNC, filamin is actin binding protein, raising the issue of whether or not it is using this tract to quickly influence the Nucleus or whether it allows it to phosphorylate things right there! we know its expression is, like the MTOR stimulated path, preserving survival! Does this open the door to MTOR Inhibitor in Pancreatic cancer? Does expression of this pathway, an opportunity to introduce MTOR inhibitors?

An interesting set of Circumstances
------------------------------------
We seem to live an interesting time, unusual things happening, the government is late doing stuff. Although it claims it is pro-business, licenses are delayed and the emphasis seems to crack down, and pay less. Shrinking everything seems to be the impetus!
The most interesting scenario is what is happening with the IRS. Because I need to meet some money demands, I filed my taxes early in February or as soon as I got my W-2 and related 1099. 4 weeks after I filed, I got a text on my phone that the IRS has rejected my filing. I thought it was a joke but sure enough I got confirmation through my e-mail and from the IRS office. We must live an interesting revolution! When the IRS is now evading tax-filing. It used to be that if you do something incorrect, the IRS corrects it. I had come to expect that and normally sent my best evaluation for their smart correction. NOW if they are rejecting Tax submission where the hell should I go? The interesting thing is, according to their not, a rejected Tax file is not a "Filing, and the can still charge me for late filing and evasion if not refiled". Can you possibly evade Taxes when you are repeatedly trying to file? The IRS is getting it both ways I believe. They refuse to do the work, and still threaten to punish me! What in the world is going on? If you figure it out, help me!

NOMENCLATURE OF GENE (III ), PANCREATIC CANCER!
BETA 4 INTEGRIN: a gene that does more than being an adhesion molecules
it is the road to a poorly described and not well recognized pathway
Not only it gives Hypertrophy but epidermolysis goes through this intergrin, it participates in the ERBB pathways. Mark my word these are critical pathways in pancreatic cancers.
MTIF GIVES YOU MOTIVES TO AFTER IT!
MAKING THE ERBIN A PLAUSIBLE TARGET.
MAKING ALSO A STRONGER CASE THAT MEMBRANE CYTOSKELETON SHOULD BE A GOOD TARGET BECAUSE OF THE WAY IT DRIVES ITS PATHWAY NOT THROUGH THE CYTOSOL( ALTHOUGH THERE IS A SECONDARY RAS/MAPK STIMULATION,) BUT THE PATHWAY HERE IS THROUGH THE RETICULUM ENDOTHELIUM DIRECTLY TO THE NUCLEUS! CONCEPTUALLY, AN ANTIBODY TO LAMININ ATTACHED TO A SUBUNIT OF A LIPOLYTIC COMPOUND SHOULD HAVE A THERAPEUTIC OR CHEMICAL EFFECT AT THIS LEVEL. AN INTERESTING APPROACH. CHANCES ARE IT MAY ALSO HAVE A STRONG IMPACT ON THE WNT-PATHWAY WHICH TRAVELS CLOSE BY AND IS IMPORTANT IN BREAST CANCER!
MTA-1: THIS IS A REAL OPPORTUNITY
Here the cell stopped fooling around trying to lie to you. Here the cell says to you this is one of my ways to metastasize. yes this is my gene to metastasize and I will work like any CBF like molecule by attaching to DNA and make me protein that will have me spread like wild fire! And by the way, I will use a growth hormone like Estrogen. No kidding around.
"MTA1 has been shown to interact with HDAC1,[4][5] Histone deacetylase 2,[4][6][5] MTA2,[4] Estrogen receptor alpha[7][5] and MNAT1.[8] MTA1 has also been shown to inhibit SMAD7 at the transcriptional level[9]"
IT DOES NEED TGF TO WORK, TGF IS FOR LOCAL GROWTH ANYWAY, THAT IS WHY IT BLOCKS THE SMAD.
SPINT2
Mutation at SPINT2 leads to significant Malignant Ascites and peritoneal invasion, SPINT 2 is a suppressor of this phenomena. On the Intestinal membrane deficiency of SPINT2 leads to sodium induced/containing diarrhea. This is also true in Ovarian cancer or peritoneal based tumors. Targeting this is better than trying Avastin, a blind approach when it comes to effusion management.
MMP11
A metalloproteinase, aimed at breaking down extracellular matrix and be on the move. Targeting MMP for cancer has proven futile. The cell is not stupid, it does not put out things that are going to hunt it! It builds first a strong inhibitor to metalloproteinases. In fact, the lack of inhibitors has been recognized as the main pathogenesis of TTP. With the ADAMs being the integrins involved! and next is that Inhibitor which is, of course, expressed in pancreatic cancer.
TIMP1
TIMP metallopeptidase inhibitor 1, also known as TIMP1, a tissue inhibitor of metalloproteinases, is a glycoprotein that is expressed from the several tissues of organisms.
This protein a member of the TIMP family. The glycoprotein is a natural inhibitor of the matrix metalloproteinases (MMPs), a group of peptidases involved in degradation of the extracellular matrix. In addition to its inhibitory role against most of the known MMPs, the encoded protein is able to promote cell proliferation in a wide range of cell types, and may also have an anti-apoptotic function.
==============
PRKCA see PRKCG
Here Phorbol esters, diacylglycerol, and calcium become important for the cell performance of various functions. Did I mention few targets, I truly believe I did!
CDH1 The Cadherin by excellence, not only important as adhesion molecule and role in metastasis. Its role is amplified by what else anchors here such as Vinculin, and others molecules such as Plakoglobins, amplifying the role. Remember even Cytochrome C is anchored at the mitochondrial membrane and its release leads to apoptosis!
The anchors are legitimate targets therefore, and brings to mind NACA1 in the anchoring to Histone deacetyl transferase (SEE OUR LEUKEMIA SECTION) CDH13 THAT'S ANOTHER BALL GAME ALL TOGETHER. THE CELL TWEACKS SOMETHING AND IT IS ANOTHER BALL GAME ALL TOGETHER!
==========================
it is the road to a poorly described and not well recognized pathway
The LysRS-Ap4A-MITF signaling pathway
The LysRS-Ap4A-MITF signaling pathway was first discovered in mast cells, in which , the MAPK pathway is activated upon allergen stimulation. Lysyl-tRNA synthetase (LysRS), which normally resides in the multisynthetase complex with other tRNA synthetases, is phosphorylated on Serine 207 in a MAPK-dependent manner.[30] This phosphorylation causes LysRS to change its conformation, detach from the complex and translocate into the nucleus, where it associates with the MITF-HINT1 inhibitory complex. The conformational change switches LysRS activity from aminoacylation of Lysine tRNA to diadenosine tetraphosphate (Ap4A) production. Ap4A binds to HINT1, which releases MITF from the inhibitory complex, allowing it to transcribe its target genes.[31] Activation of the LysRS-Ap4A-MITF signaling pathway by isoproterenol has been confirmed in cardiomyocytes, where MITF is a major regulator of cardiac growth and hypertrophy.[32][33](wikipedia)Not only it gives Hypertrophy but epidermolysis goes through this intergrin, it participates in the ERBB pathways. Mark my word these are critical pathways in pancreatic cancers.
