microRNAs

Correctly modeling biological energy

The light-activated “origins of life” issue (see: Correctly modeling ecological adaptation) forces others to come out of the woodwork and try to overwhelm the biologically underinformed masses with the complexities of their existence after decades of attributing what is currently known about viruses, viral microRNAs, entropic elasticity, anti-entropic biological energy from the sun, and nutrient-dependent microRNAs, to mutations and evolution. Theorists have denied the obvious facts about light-induced amino acid substitutions and cell type differentiation controlled by the physiology of…

UV-light mutations and gene loss (not gain)

The Neanderthals live on in us March 13, 2015 Excerpt: “He opted instead for a medical degree and then a PhD at the University of Uppsala, where he was supposed to be probing the DNA secrets of a virus.” My comment: If he had done what he was supposed to be doing, he might have learned how viral microRNAs and nutrient-dependent microRNAs contribute to cell type differentiation in all cells of all individuals of all species. If he had done…

Luis P. Villarreal tells it like it is

Luis P. Villarreal has led the way towards discovery of the “origins of life.” He has helped to elucidate what is currently known about how the epigenetic landscape becomes the physical landscape of DNA in the organized genomes of species from microbes to humans. Kudos to Suzan Mazur for admitting that she missed learning about his works. Perhaps a few neo-Darwinian evolutionary theorists will also admit they have missed something very important about the role of viruses in cell type…

Two types of microRNA are not double agents

Study details microRNA’s role as a double agent during Hep C infection By coopting miRNA-122, the virus appears to alter gene expression in the liver Excerpt: “What if chronic low levels of miRNA-122 prompt changes that, over years, contribute to liver damage and cancer? This could be a molecular link between the viral infection and the pathologies associated with hepatitis C,” Luna says. “More work on miRNA-122 targets in hepatitis C-infected patients may clarify why some go on to develop…

Implicating microRNAs in cancer

Genome-wide CRISPR Screen in a Mouse Model of Tumor Growth and Metastasis Reported as: In vivo CRISPR-Cas9 screen sheds light on cancer metastasis and tumor evolution Excerpt: “Unexpectedly, the screen also implicated several microRNAs — small RNA segments that are functional in the cell. More experimental work remains to fully explore the genes and microRNAs uncovered in the screen.” It is the perturbed balance of viral microRNAs and nutrient-dependent microRNAs that obviously makes the difference between RNA-directed DNA methylation and…

Rejecting what is known about viral microRNAs and nutrient-dependent microRNAs

Of Cells and Limits Leonard Hayflick has been unafraid to speak his mind, whether it is to upend a well-entrenched dogma or to challenge the federal government. At 86, he’s nowhere near retirement. By Anna Azvolinsky | March 1, 2015 Excerpt: The rejection letter came from Francis Peyton Rous who received the Nobel Prize a few years later for his discovery of chicken tumor viruses. My comment: My 2014 invited review of nutritional epigenetics detailed how differences in the microRNA/messenger…

Nutritional epigenetics, exercise, and immune system integrity

Anti-inflammatory mechanism of dieting and fasting revealed Summary: Researchers have found that a compound produced by the body when dieting or fasting can block a part of the immune system involved in several inflammatory disorders such as type 2 diabetes, atherosclerosis, and Alzheimer’s disease. My comment: For the obvious link from nutrition and exercise to reproduction and RNA-mediated transgenerational epigenetic effects on the morphological and behavioral phenotypes of all species that must “move” to find food or to find mates…

Are viruses microRNAs? (2)

The role of microRNAs in cell type differentiation can be compared in the context of the role of viruses and mutations that cause cancer. Facts provide a basis for explaining the biological basis of epigenetically-effected cell type differentiation in species from microbes to man. But first, those who are biologically uninformed must answer the question: Are viruses microRNAs? Andrew Jones aka anonymous_9001 is correct. Viruses are not microRNAs. anonymous_9001 5 / 5 (6) 11 hours ago Stupid question of the…

Are viruses microRNAs?

Evolution of Intelligent Viruses and Jumping Genes Conclusion: “…it is intelligent warfare between mobile genetic elements and the epigenetic responses of the cell that, most likely, determines evolution.” My comment: This conclusion appears to place biologically-based cause and effect into the context of viruses and evolved immune system responses. Epigenetically-effected immune system responses can be compared in the context of epigenetic effects on cell type differentiation that link ecological variation to ecological adaptation. This puts cause and effect into their…
