RNA-mediated toxicity

MicroRNAs GnRH and the failure of sex research

Summary: “The Bull Sperm MicroRNAome and the Effect of Fescue Toxicosis on Sperm MicroRNA Expression” accurately represents what is known about food energy-dependent RNA-mediated cell type differentiation in species from soil microbes to humans. MicroRNAs are not new players in the hypothalamic control of fertility and the effects of food odors and pheromones on microRNAs link energy-dependent changes in hormones to behavior. That fact was detailed two decades ago in our Hormones and Behavior review. Now see: [MicroRNAs: new players…

Infections and age change the odor of wine and people

Summary: Food energy is a direct link from electron spin via changes, which link the sense of smell in bacteria from changes in angstroms to ecosystems in all living genera. Fruity with a note of fungus: How fungal infections change the aroma of wine …while bunch rot actually led to more positive aroma ratings due to the increased levels of fruity- and vanilla-like notes, powdery mildew decreased the level of pleasant notes in the wine, so that it received more negative…

From E. coli to monkeys and mankind: Theories vs models (2)

Dedicated to Dr. Tom Jordan and Priscilla Jordan on the day of their retirement from the Baptist ministry, May 28, 2017. They always encouraged me to learn more about the “Laws of Biology” and link the Laws from energy as information to all biodiversity on Earth via the physiology of reproduction. See also: From E. coli to monkeys and mankind: Theories vs models High-throughput biochemical profiling reveals sequence determinants of dCas9 off-target binding and unbinding (5/23/127) …changes in observed association…

Ignoring peer review, ATP, and microRNA biosynthesis

Cell diversity and network dynamics in photosensitive human brain organoids …neuronal activity within organoids could be controlled using light stimulation of photosensitive cells, which may offer a way to probe the functionality of human neuronal circuits using physiological sensory stimuli. They are not going to tell anyone that these findings link the speed of light on contact with water to the energy-dependent physiology of reproduction in all living genera because the physiology of reproduction is nutrient-dependent and pheromone-controlled. Everyone knows…

All of “like kind” in the (bigger) family (2)

See first: All of “like kind” in the (bigger) family Excerpt: Researchers who want to understand why the changes occur should be among the first to examine how fixation of the amino acid substitutions occurs in the DNA of organized genomes. For example, fixation of amino acid substitutions appears to occurs via the nutrient-dependent pheromone-controlled physiology of reproduction in species from microbes to man. Instead SICB dictator Billie Swalla and her co-authors made a ridiculous claim. How could their data…

What is life without sunshine?

Summary: It seems likely that Schrodinger’s anti-entropic virucidal effect of sunlight will be linked to the RNA-mediated de novo creation of all organized genomes and the maintenance of the “spotless epigenome” in this presentation later today. If so, even theorists and other pseudoscientists who planned to “March for Science” will finally be seen in the context of Dobzhansky’s claims about the “…light of evolution.” Erasing Epigenetic Marks: Eternal Sunshine of the Spotless Epigenome Topics to be covered: The variety of…

Viruses in pathogenic variants disrupt alternative splicings

Pathogenic variants that alter protein code often disrupt splicing Approximately 10% of exonic mutations altered splicing, mostly by disrupting multiple stages of spliceosome assembly. We present a large-scale characterization of exonic splicing mutations using a new technology that facilitates variant classification and keeps pace with variant discovery. Assay of nearly 5,000 mutations reveals roots of genetic splicing errors “Splicing errors can be very deleterious because instead of just changing one amino acid [the building block of a protein], it can…

Epigenetically-effected nucleosome repositioning sheds Dobzhansky’s light on evolution

Crystal structure of the overlapping dinucleosome composed of hexasome and octasome My summary: Nucleosomes are dynamic entities that are repositioned by energy-dependent links from sunlight to ATP and RNA biosynthesis that act on DNA during the chromatin remodeling, which is biophysically constrained by the pheromone-controlled physiology of reproduction during the transgenerational epigenetic inheritance of all morphological and behavioral phentoypes. processes. Reported as: Unveiling how nucleosome repositioning occurs to shed light on genetic diseases …an incomplete formation of overlapping dinucleosome may…

Functionally interdependent editing and methylation

Editing and methylation at a single site by functionally interdependent activities …cytosine 32 in the anticodon loop of Trypanosoma brucei tRNAThr is methylated to 3-methylcytosine (m3C) as a pre-requisite for C-to-U deamination. Formation of m3C in vitro requires the presence of both the T. brucei m3C methyltransferase TRM140 and the deaminase ADAT2/3. Once formed, m3C is deaminated to 3-methyluridine (m3U) by the same set of enzymes. ADAT2/3 is a highly mutagenic enzyme4, but we also show that when co-expressed with…

Cytosis: Biology Content

  Help Me Write Some Biology Content Project Update #5: Cytosis: A Cell Biology Board Game by John Coveyou (Genius Games) Many of you have mentioned that you’d like to have an explanation of the biology behind Cytosis available… and I think that is an AWESOME plan. Every time I’ve taught the game to non-science players in the past, they say gameplay made even more sense (and was so much more enjoyable) when I explained the science as well. This…
