Physics, Chemistry, and Molecular biology (PCMb)

human-evolution

Physics, Chemistry, and Molecular biology (PCMb) link ecological variation to ecological adaptations via a model of gene-cell-tissue-organ-organ system complexity that I first presented in 1992. After adding gene activation by pheromones, I co-authored a book that linked the pheromone-controlled physiology…

A microRNA-mediated mechanism that is epigenetically inherited

Pregnancy Stress Spans Generations The stressors a female rat experiences during pregnancy can have repercussions for her granddaughters, a study shows. By Anna Azvolinsky | August 7, 2014 Excerpt: “These changes could be the result of a microRNA (miRNA)-mediated mechanism, which may be epigenetically…

Nutrient-dependent chromatin organization?

Snf2h-mediated chromatin organization and histone H1 dynamics govern cerebellar morphogenesis and neural maturation open access Conclusion: “…delineating the epigenetic regulation of neuronal development is crucial to our understanding of intellectual-disability disorders caused by mutations in epigenetic modifying enzymes. As a whole,…
