How would you go about reprogramming cancer cells back to normalcy? You would first identify the most likely candidate(s) for Cell Recognition Factor(s) and determine how they change during the development of, let's say, a pancreatic cell. From the time of the first egg mass to mature adult cell, what CRF's were being expressed?

Take these and chemically attach them to a carrier that is able to diffuse through tissue. Inject the complex into the blood or lymphatic system. Repeat the cocktail until normalcy is achieved. Once we know the exact sequence that particular CRF's are expressed, we can just inject stage-specific CRF's in a particular sequence.

A difficulty that I'm hoping does not present itself is that of individual variations in CRF's. We may not want to have to design a sequence on an individual basis. It would be much better, at least initially, if one sequence for differentiation of pancreas cells was the same for all individuals.

Essential elements of this theory:

A. With the exception of lymphocytes, cells should not have the capability of existing anywhere in an organism.
B. Apoptosis or Killer cell is activated to eliminate "foreigners" that attempt to exist in an inappropriate location.
C. Cells that lose contact begin expressing earlier CRF's. This encourages Killer Cell targeting. If not killed, cells begin other reprogramming activity.
D. Once a CRF is expressed that is "early" enough, the cell begins acting like early embryo cells and exibit migratory (metastatic) behavior.
E. If the cell is supplied with early CRF's, it could be reprogrammed into a differentiated state.


Note: Cancer cells do communicate which each other but because they are embryonic, they continually seek CFR's that are not there. Even at the most primitive stages, the cancer cell is expecting other signals that are not being provided. Perhaps the womb had CRF's. If I were searching for CRF candidates to use in cancer, I would start with that very earliest of environments.

Recently, in one of the few papers that I could access free, I came across a statement saying that HDAC inhibitors could be used to bring on differentiation. HDAC modifies histones so that they bind more strongly with DNA. If you inhibit this action, you increase transcription, and cancer cells have been seen to differentiate to a normal state upon being treated with an HDAC inhibitor. These findings support the CRF theory of cancer because the cancer cell, now with a less restricted genome, begins to express the right CRF for its present niche.

This article was recently published in PLOS. This is a great scientific publishing medium that doesn't charge anyone a cent to read their stuff, unlike Science and Nature and the others that hoard their publications at the expense of humanity. Anyway, the article points out that a boy being treated with stem cells for a rare genetic condition developed tumors of the brain and spinal cord. These results should come as no surprise for readers of this blog. The cells injected into the nerve tissues were allografts--they were obtained from a source other than the patients own tissues. These clearly will not be at home in another person's body and they will begin to express embryonic Cell Recognition Factors in the hope that they could establish communication. As we have learned here, a cell must know exactly where it is. Such communication must exist. If it does not, it would mean that A) any manner of invader could easily make its home in another multicellular organism, or B) any...

What about the unattached cell?

While this procedure is not what I had in mind when I spoke of being able to reprogram the cancer cell, I'm nevertheless glad that reprogramming was found to be possible for the unattached cancer cell. The unattached immune cell is needed everywhere in the body and it would make sense for a cancer derived from an immune cell to differentiate into other immune cells as needed. This is what was found by the Stanford researchers--reprogramming of leukemia cells into normal granulocytes and macrophages via supplied ligands or transcription factors. The initial observation from Stanford came about as a result of a shotgun approach. This approach should also be used for the solid tumor and if their cocktail doesn't do it, I would consider extracting Embryonic Cell Surface molecules from various developmental time points. Finding the right CRF for the differentiation of  solid tumors is right around the corner. My next post will be one showing what the CRF theory helps explain wh...
