Use of definitions in attempts to explain any aspect of species-specific biophysically constrained cell type differentiation and aging has been replaced by the use of model systems of biological processes.  Biological processes can be compared to so-called “evolutionary processes” to show that only biological processes need to be considered in the context of Darwin’s “conditions of life” or answers to the the question  What is Life? Schrödinger (1944). K. L. Mettinger et al. (eds.), Exosomes, Stem Cells and MicroRNA, Advances…

Evolutionary determinants of genome-wide nucleotide composition January 1, 2018 1) They place their thoughts about mutation rates into the context of compatibility with mutational spectra. 2)They claim the mutation rate can be linked to mutational spectra that may be free to wander across evolutionary time. 3) They ignore facts that link the energy-dependent maintenance of a suppressed constant genome-wide deleterious rate that obviously occurs in the context of the Virus-mediated archaeal hecatomb in the deep seafloor 4) They eliminate the…

Excerpt: During the past 21 months, others have either learned nothing about microRNAs or they have ignored the fact that virus-driven energy theft is not the same as energy dissipation in the context of food energy (the quantized energy as information that is used by viruses to create the amino acid substitutions that stabilize their RNA and DNA). The dark side of the new popularity of cryo-electron microscopy …we need to stand together as a field, and support our colleagues…

The molecular dynamics of the hydrophobic amino acid, valine, link the anti-entropic virucidal energy of sunlight from the Second Law of Thermodynamics to the energy-dependent and temperature-dependent orientational dynamics of the structure of water via methylation and acetylation in the C and N terminus, respectively. The quantized energy of sunlight must be linked from energy as information to energy-dependent methylation and acetylation to all biodiversity via the effect of the energy on contact with water and the physiology of pheromone-controlled…

Summary: Emmy Noethe’s theorems were developed in the early 1900’s. Richard Feynman inadvertently or purposefully alluded to them as examples of human idiocy. Discover Magazine resurrected the examples of human idiocy in a 2017 article. For comparison, Choi et al., (2017) support the claims that intercellular and interkingdom communication is energy-dependent and controlled by the metabolism of food energy to pheromones. It is obvious that pheromones biophysically constrain the virus-driven degradation of messenger RNA. That fact links everything currently known…

GDNF-Transfected Macrophages Produce Potent Neuroprotective Effects in Parkinson’s Disease Mouse Model Excerpt: …genetically-modified macrophages released exosomes with incorporated GDNF that may facilitate GDNF transport into the target cells and preserve it against degradation. published 9/17/14 and reported on 9/11/15 as: Smart cells teach neurons damaged by Parkinson’s to heal themselves Excerpt: In addition to delivering GDNF, the engineered macrophages can “teach” neurons to make the protein for themselves by delivering both the tools and the instructions needed: DNA, messenger RNA…

The Exosome Is Recruited to RNA Substrates through Specific Adaptor Proteins Reported as: The exosome regulates the processing, degradation, and surveillance of a plethora of RNA species. Excerpt: …the exosome employs a general mechanism of recruitment to defined substrates and that this process is regulated through adaptor proteins. Journal article excerpt: (subscription required) The nuclear exosome processes precursors of numerous stable RNA species (Allmang et al., 1999) (rRNA, snoRNA, and snRNA) and degrades by-products of RNA processing reactions. Additionally, it…

See also: Viral and Cellular Genomes Activate Distinct DNA Damage Responses Excerpt: Central to life is the faithful replication, inheritance, and maintenance of genomic DNA. The MRE11/RAD50/NBS1 (MRN) complex andATMplay a critical role in this biological mandate (Ciccia and Elledge, 2010). Cellular double-strand breaks (DSBs) are sensed by MRN and trigger the assembly of DNA damage response (DDR) foci that amplify global ATM signaling to induce cell-cycle arrest and DNA repair (Polo and Jackson, 2011). DNA viruses are an ancient…
