Abiogenesis vs microRNA biogenesis

Summary: The pseudoscientific nonsense about abiogenesis that has been touted by Karo Michaelian and others like him has caused the unnecessary suffering and premature death of millions to billions of people by placing the pathogenic consequences of deregulated miRNAs into the context of ridiculous theories. See for comparison: Structural diversity of supercoiled DNA and the parody from the same research group: ——————————- Abiogenesis (2017) Microscopic dissipative structuring and proliferation at the origin of life (Oct 13, 2017) Some fundamental molecules…

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…

The eternal significance of microRNAs (1)

Common Allele Linked to Sugar Consumption Leads to Lower Body Fat, Higher Blood Pressure One energy-dependent change in a base pair is linked from the FGF21 rs838133 variant to microRNA-mediated changes in morphology and behavior. The quantized energy as information link from microRNAs to morphology and behavior is common to my mouse-to-human model of sympatric speciation. By linking the common allele to sugar consumption, the authors attest to the fact that sympatric speciation is quantized energy-dependent. Energy as information biophysically constrains…

Complexity: Routes and Patterns (2)

Role of RNA modifications in brain and behavior “Here, we summarize current knowledge of cellular consequences of RNA modifications, with a special emphasis on neuropsychiatric disorders. We present evidence for the existence of an “RNA code,” similar to the histone code, that fine‐tunes gene expression in the nervous system by using combinations of different RNA modifications.” Different RNA modifications were referred to as alternative splicings of pre-mRNA in the molecular epigenetics section of this 1996 Hormones and Behavior review: From…

Psychophysical Laws of Biology: RNA-mediated nutritional psychiatry (3)

Psychophysical Laws and the Superorganism  (open access) …superorganisms may also exhibit such behaviour, suggesting that these laws arise from fundamental mechanisms of information processing and decision-making. Reported on Jun 14, 2013 as Nutrient-dependent/pheromone-controlled adaptive evolution: a model and again on: Mar 27, 2018 as Honeybees may unlock the secrets of how the human brain works The study… found that superorganisms may obey the same laws as the human brain. Kohl’s “Laws of Biology” and Darwin’s “conditions of life” can now be…

RNA-mediated nutritional psychiatry (2)

Codon identity regulates mRNA stability and translation efficiency during the maternal-to-zygotic transition The amino acid optimality code (Fig 6) provides an alternative perspective on sequence changes between paralogs in evolution and human disease. Neo-Darwinian theorists dispense with Darwin’s food energy-dependent  “conditions of life.” They link mutations and disease to evolution via mathematical models. They exemplify human idiocy. See for example: Neopterygian phylogeny: the merger assay Reported as: Adaptive radiations in the Mesozoic Bony fishes are the most diverse of all…

RNA-mediated nutritional psychiatry

Summary: Young Genes are Highly Disordered as Predicted by the Preadaptation Hypothesis of De Novo Gene Birth Stop this nonsense about de novo gene birth and you will help to stop the school shootings without more gun control. See my presentation at the 2017 Precision Medicine Virtual Conference (2/15/17) Energy as information and constrained endogenous RNA interference See also: Pat Sweeney et al (3/13/2017) Protein misfolding in neurodegenerative diseases: implications and strategies.  A notable development is the creation of collaborative…

Part 2: Light-controlled cell biology (revisited)

Greg Bear took the lead with this approach in his novel Quantico (2006). A genetically engineered virus was used to erase the memory of a specifically targeted human population to reduce inter-ethnic conflict. [Greg Bear] …served as a consultant for NASA, the U.S. Army, the State Department, the International Food Protection Association, and Homeland Security on matters ranging from privatizing space to food safety, the frontiers of microbiology and genetics, and biological security. Greg Bear is a likely candidate for…

Ecological adaptation: A new definition of heredity (3)

Excerpt: Moving forward: Novel and Haplotype Specific MicroRNAs Encoded by the Major Histocompatibility Complex …these data suggest that a subset of the identified novel miRNAs may contribute to the pathophysiology of numerous diseases, laying the groundwork for future studies to elucidate the functional connections of miRNAs to the numerous diseases associated with sequence variants within non-coding regions of the MHC. OMCD: OncoMir Cancer Database Dysregulation of miRNAs is commonly observed in cancers and it largely cancer dependent. The virus-driven theft…

A reversible TCA cycle in a thermophile (3)

A pathway for mitotic chromosome formation The combination of nested loops distributed around a helically twisted axis plus dense chromatin packing achieves the 10,000-fold compaction of chromatin into linearly organized chromosomes that is required for accurate chromosome segregation when cells divide. The compaction of chromatin in the context of hydrophobicity is the topic of: Structural diversity of supercoiled DNA Our data provide relative comparisons of supercoiling-dependent twisted, writhed, curved, and kinked conformations and associated base exposure. Each of these structural…
