Nutrients to remedy cancer STEM cells

Dr. Weeks’ Comment: Once again science catches up to common sense. For the past 30 years we have taught that, before medications are called upon, we should optimize nutrition.  Dr. Weeks teacher Dr. Abram Hoffer Ph.D. M.D. coined the phrase “orthomolecular” to indicate that we should start by correcting imbalances before depending upon foreign substances like patented prescription medications. The revolution in cancer care which Dr. Weeks has lectured on for the past 10 years has been to ignore the cancer TUMOR cell and to focus on remedying the cancer STEM cell – a far more lethal cancer entity.  Now we see that nutrients are required to control the cancer STEM cells.

An International Reserach Team coordinated by Igb-Cnr has discovered a key role of vitamins and amino acids in pluripotent stem cells. The research is published in Stem Cell Reports, and may provide new insights in cancer biology and regenerative medicine

Vitamins and  play a key role in the regulation of epigenetic modifications involved in the progression of diseases such as cancer. The research may have future implications in . The study was published in Stem Cell Reports.

“We found that two metabolites, vitamin C and the amino acid L-Proline, are important players in the control of stem cell behaviour. This study shows that pluripotent embryonic stem cells present in the earliest phases of development are pushed toward a more immature ‘naive’ state by vitamin C, while they are forced to acquire a ‘primed’ state in the presence of L-Proline. Thus, vitamin C and L-Proline exert opposite effects on embryonic stem cells, and this correlates with their ability to modify DNA (DNA methylation) without altering the sequence, but instead, the regulation of gene expression,” explained researcher Gabriella Minchiotti.

Stem cells possess the unique ability to self-renew and differentiate into other cell types, which makes them extremely interesting in medical and biological research. “Embryonic stem cells are the most ‘potent’ (defined as pluripotent), meaning that they can give rise to all cell types of an organism, such as cardiomyocytes, neurons, bones, etc. Like normal stem cells, cancer stem cells can also self-renew and differentiate, and are believed to be responsible for tumor growth and therapy resistance.”

This study provides an important contribution to the understanding of how metabolites regulate pluripotency and shape the epigenome in , which have been largely unexplored and recently gained great interest. This knowledge not only enhances our understanding of the biology of normal  but may offer novel insights into  biology, identifying novel potential therapeutic targets.
