Chromatin: The structure of DNA

Update on Inflammation and Degenerative Brain Disease Excerpt: While mapping connections of neurons has become the holy grail of current neuroscience, it is clear that communication of neurons with many other types cells is, also, vitally important to every aspect of brain function. My comment: Understanding dementia was placed into the context of understanding how virus-driven energy theft alters the de novo creation of olfactory receptor genes and causes the loss of function that is linked to all pathology via…

Consciousness is simply food rearranged

The claim that consciousness is simply food rearranged can be placed into a historical perspective that crosses more than 70 years. Historical perspective: (1944) What Is Life? Excerpt: Indeed, in the case of higher animals we know the kind of orderliness they feed upon well enough, viz. the extremely well-ordered state of matter in more or less complicated organic compounds, which serve them as foodstuffs. After utilizing it they return it in a very much degraded form -not entirely degraded,…

Misunderstanding cancer

Tumor-Only Genetic Sequencing May Misguide Cancer Treatment in Nearly Half of All Patients, Study Shows Excerpt 1) “…they counted 382 possible tumor-related changes. But after comparing a patient’s full germline genome to his or her tumor genomes, they determined that, on average, 249 of these changes were part of the patient’s normal, inherited genetic variation and were not tumor-specific.” Excerpt 2) “In addition to selecting personalized therapies for patients with cancer, sequencing the normal tissue genome can also increase the…

An epigenetic trap (the prequel)

See also: An epigenetic trap (the sequel) Excerpt: “Support for the link from one epigenetic trap to cell type differentiation was included in the molecular epigenetics section of our 1996 review, which detailed how RNA-mediated chromatin remodeling occurs.” My comment: One epigenetic trap leads to the de novo creation of olfactory receptor genes and cell type differentiation. See also: Heterochromatin-mediated gene silencing facilitates the diversification of olfactory neurons. The first epigenetic trap links the sun’s biological energy to cell type…
