RNA-mediated physics, chemistry, and molecular epigenetics (3)
reported as: Using microRNAs to target cancer cells By Dawn Hayward
MicroRNAs stand out from conventional gene-therapy-based approaches and have a niche in lipid metabolism. They can be designed specifically to target a gene and serve as modulators rather than on/off switches. Increased lipid formation and breakdown in cancer cells creates vulnerability that might be taken advantage of by microRNAs. In addition, cancer as a whole involves a combination of many factors, and microRNAs could lead the attack as professional pathway regulators to reset the normal metabolic landscape.
My comment: Metabolic networks are linked to genetic networks by the normal metabolic landscape, which is linked to healthy longevity. Virus-driven energy theft links changes in the metabolic landscape to changes in the physical landscape of supercoiled DNA, which typically maintains healthy longevity across the lifespan by preventing virus-driven entropy. When no consideration is given to facts about virus-driven entropy, you are stuck with theories about brain evolution.

My comment: Place that claim into this regression.

An Ancient Transkingdom Horizontal Transfer of Penelope-Like Retroelements from Arthropods to Conifers 4/1/16

My comment: “Among different bacterial species existing in similar environments, DNA uptake (Palchevskiy & Finkel, 2009) appears to have epigenetically ‘fed’ interspecies methylation and speciation via conjugation (Fall et al., 2007; Finkel & Kolter, 2001; Friso & Choi, 2002). This indicates that reproduction began with an active nutrient uptake mechanism in heterospecifics and that the mechanism evolved to become symbiogenesis in the conspecifics of asexual organisms (Margulis, 1998). In yeasts, epigenetic changes driven by nutrition might then have led to the creation of novel cell types, which are required at evolutionary advent of sexual reproduction (Jin et al., 2011). These epigenetic changes probably occur across the evolutionary continuum that includes both nutrition-dependent reproduction in unicellular organisms and sexual reproduction in mammals. For example, ingested plant microRNAs influence gene expression across kingdoms (Zhang et al., 2012). In mammals, this epigenetically links what mammals eat to changes in gene expression (McNulty et al., 2011) and to new genes required for the evolutionary development of the mammalian placenta (Lynch, Leclerc, May, & Wagner, 2011) and the human brain (Zhang, Landback, Vibranovski, & Long, 2011).” — Kohl (2012)
My comment: Place all claims (above) that link nutrient-dependent ecological adaptations into the context of healthy longevity. Place all claims (below) into the context of virus-driven energy theft and all pathology.

My comment: Place all claims about nutrient energy-dependent cell type differentiation and all claims that link virus-driven energy theft into the context of physics and chemistry linked to the conserved molecular mechanisms of cell type differentiation in twin studies.

reported on 5/5/16 Starving cancer the key to new treatments
The research team blocked gateways through which the cancer cell was obtaining the amino acid glutamine and found the cells almost completely stopped growing.
My comment: They prevented the viruses in the cancer cell from adapting. Otherwise, energy theft enables amino acid substitutions in the virus that would link ecological variation to healthy longevity when nutrient-stress or social stress is biophysically constrained. Links from the epigenetic landscape to the physical landscape of supercoiled DNA biophysically constrains energy-dependent RNA-mediated cell type differentiation. They have been placed into the context of mutation-driven evolution by theorists who have killed millions with their ridiculous theories.
