Cancer in Microgravity

Joshua Chu and others have shown that microgravity hinders the cancer cell.

This is not surprising being that a cell needs to anchor itself before it can pull apart its chromosomes. Unable to pull apart the chromosomes, a cancer cell would then stop dividing or, thanks to numerous checkpoints, would not even start the process.

I still haven't determined definitively whether the CRF's are the molecules anchoring the cell. I don't think they are because prior to multicellularity, animal cells still needed to anchor themselves prior to cell division and would have cell surface molecules specifically for that purpose. I don't know of any free-swimming unicellular animals that do not require anchoring in order to reproduce. The free-swimming yeast cell has a rigid cellulose wall with which to anchor its microtubules.

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...
