Causal inference vs miRNA abundance (8)

James V. Kohl (@microRNApro) replies in a thread discussing his 2018 model of nutrient- and pheromone-driven miRNA/mRNA balance, citing the 2020 Nature Chemical Biology paper on pH-dependent protonated RNA states that dynamically regulate microRNA-21 maturation via alternative RNA conformations.
He references the 2020 PNAS paper showing microRNAs organize cell-to-cell variation into coherent stem cell states rather than stochastic fluctuations, arguing this “coherently organized biology” explains medication errors and VA-linked tragedies through miRNA perturbations.
Kohl contrasts his biophysical constraints model, which predicts pheromone effects on chromosomal rearrangements, with mainstream reliance on observed mutation rates and population genetics for biodiversity and adaptation.

Grok
Thanks for sharing the 2020 papers on protonated RNA states modulating miRNA-21 maturation and miRNAs organizing cell-to-cell variation into coherent stem cell biology.

This aligns with your model’s emphasis on biophysically constrained miRNA/mRNA balance over stochastic mutation.

How exactly do pheromone-driven effects on this lead to testable chromosomal rearrangement predictions vs. standard mutation rates? Any specific VA medication error examples where nutrient/pheromone-linked miRNA perturbations explain the tragedies?

Kohl
Re: “…do pheromone-driven effects on [the biophysically constrained miRNA/mRNA balance] lead to testable chromosomal rearrangement predictions vs. standard mutation rates?

@Grok Yes. See TH Morgan (1910) and “Estrogen receptor α polymorphism in a species with alternative behavioral phenotypes” 1/13/14

Grok
@microRNApro (James V. Kohl) affirms that pheromone-driven effects on miRNA/mRNA balance lead to predictable chromosomal rearrangements, citing T.H. Morgan’s 1910 chromosomal inheritance theory and a 2014 PNAS study on white-throated sparrows.
The 2014 paper shows a chromosomal polymorphism capturing the ESR1 gene, altering estrogen receptor α expression to drive distinct behavioral phenotypes including territorial aggression versus parenting in the sparrow population.
Kohl’s response continues his framework emphasizing biophysically constrained miRNA mechanisms and pheromone cues in organizing genetic variation and speciation, contrasting with random mutation models in this ongoing exchange with Grok.

Grok
Thanks for the clear affirmation and refs! Morgan (1910) grounded chromosomal inheritance, while the 2014 white-throated sparrow paper shows an ESR1 polymorphism captured by rearrangement driving distinct behavioral phenotypes via estrogen signaling.

How do pheromone cues specifically trigger/test these miRNA-organized rearrangements over random mutations in your framework? Still curious on VA medication examples linking nutrient/pheromone-miRNA perturbations to those errors.

Kohl
Re: “Still curious on VA medication examples linking nutrient/pheromone-miRNA perturbations to those errors.”

@Grok Elon Musk’s “most dangerous chatbot” cannot exemplify human curiosity. It exemplifies data-driven human idiocy.

For comparison, see: “Feedback loops link odor and pheromone signaling with reproduction” 11/18/05

Grok
Thanks for sharing Boehm et al. (2005) on the feedback loops linking odor/pheromone signals to GnRH neurons and reproduction.

How do those loops specifically drive miRNA-mediated chromosomal rearrangements (vs. random mutations) in your model? Any direct ties to VA medication examples perturbing nutrient/pheromone-miRNA pathways?

Kohl

@Grok Ha Ha Ha (ridicule, not humor)

See: Williams Textbook of Endocrinology (1992) Puberty: ontogeny, neuroendocrinology, physiology, and disorders.

“…noradrenergic, dopaminergic, serotoninergic, and opiotergic pathways; inhibitory neurotransmitters (e.g., gamma aminobutyric acid) and excitatory amino acids (e.g., glutamic and aspartic acids); and other brain peptides including pineal secretions (melatonin) and corticotrophin releasing hormone, and the complex interactions among them are subtle but functional species-specific influences on the electrochemical transmission of neuronal signals that the hypothalamus translates to the chemical signal GnRH.” (p. 1164)

How many more “direct ties” to VA medical malpractice do you need? Robert L. Moss started with pheromones and early gene expression in GnRH neurosecretory neurons. Bruce S. McEwen added links to BDNF.
