EDAR gene

Environmental selection is natural selection

Environmental selection during the last ice age on the mother-to-infant transmission of vitamin D and fatty acids through breast milk was published on April 23, 2018 The ectodysplasin A receptor (EDAR) gene has a range of pleiotropic effects, including sweat gland density, incisor shoveling, and mammary gland ductal branching. The frequency of the human-specific EDAR V370A allele appears to be uniquely elevated in North and East Asian and New World populations due to a bout of positive selection likely to…

The eternal significance of microRNAs (1) – revisited

I have never been forced to revisit a blog post on the day after it was posted, until now. The Scientist has misrepresented everything known to all serious scientists about the eternal significance of microRNAs in: Sweet Tooth Gene Tied to Less Body Fat “These results suggest that FGF21 has pleiotropic effects, with separate effects on macronutrient intake to those on body shape and blood pressure,” the authors write in their report. My comment to The Scientist See All About…

Losers: Rediscovering an epigenetic key (2)

Genome-wide meta-analysis associates HLA-DQA1/DRB1 and LPA and lifestyle factors with human longevity “Validation of associations reported elsewhere,” includes the detailed associations from 1996 in the molecular epigenetics section of: From fertilization to adult sexual behavior  and in my 2013 refutation of neo-Darwinian theories: Nutrient-dependent/pheromone-controlled adaptive evolution: a model  (Val370Ala is also known as rs3827760, also known as 1540T/C, 370A. It is a SNP in the ectodysplasin A receptor EDAR gene on chromosome 2.) Excerpt: Two additional recent reports link substitution…

2016 obfuscated facts about energy as information

Illumination of the fluorescent biomarker in green revealed that the adult mouse brain could be infected by Zika in a region called the subgranular zone of the hippocampus. Full of neural progenitor cells, this part of the brain is important in learning and memory. Credit: Laboratory of Pediatric Brain Disease at The Rockefeller University/Cell Stem Cell As reported by Bob Yirka in: Best of Last Year – The top Medical Xpress articles of 2016 a team of MIT biologists reported…

Sudden death indel polymorphism

An insertion/deletion polymorphism within 3’UTR of RYR2 modulates sudden unexplained death risk in Chinese populations. …different alleles of rs10692285 could alter the local structure of RYR2 mRNA and microRNA (miRNA) binding. See for comparison: Modeling Recent Human Evolution in Mice by Expression of a Selected EDAR Variant The differences between the 370A knockin mouse phenotypes and those of loss- and gain-of-function models emphasize the advantage of a more accurate mouse model. In this study an adaptive variant links the mouse…
