Autophagy in health and disease (1)

Novel Treatment Strategies for the Nervous System: Circadian Clock Genes, Non-coding RNAs, and Forkhead Transcription Factors Each of these pathways have an intimate relationship with the programmed death pathways of autophagy and apoptosis and share a common link to the silent mating type information regulation 2 homolog 1 (Saccharomyces cerevisiae) (SIRT1) and the mechanistic target of rapamycin (mTOR). Circadian clock genes are necessary to modulate autophagy, limit cognitive loss, and prevent neuronal injury. Non-coding RNAs can control neuronal stem cell…

Diet-driven RNA interference and mental health (4)

See: Diet-driven RNA interference and mental health (3) Social transmission and buffering of synaptic changes after stress Transmission from the stressed subject to the naive partner required the activation of PVN CRH neurons in both subject and partner to drive and detect the release of a putative alarm pheromone from the stressed mouse. Reported as: Researchers discover brain cells change following close contact with a stressed individual “There has been other literature that shows stress can be transferred — and…

Enzyme-constrained interethnic biodiversity (5)

Conclusion: The problem with -omics is that biologically uninformed researchers keep throwing more bricks into the brickyard but they fail to use any of the bricks to build a model of anything akin to how the energy-dependent functional structure of supercoiled DNA or its diversity is created. The biologically uninformed pseudoscientists end up creating only a brick yard or building a partially constructed wall that prevents serious scientists from getting to the facts about supercoiled DNA The Structural diversity of…

Until death: Virus-driven failure of multisensory integration (2)

Summary: The virus-driven degradation of messenger RNA is clearly linked to frontotemporal dementia (FTD) by altered language, personality, behavior, cognition and motor function. What causes FTD? If the virus-driven degradation of messenger RNA causes all pathology, I would expect to find a link from microRNAs to the pathology and to the effective treatment. The social and economic burden of frontotemporal degeneration Reported as: Study reveals staggering economic burden of dementia in younger people Frontotemporal degeneration (FTD) accounts for 20 to…

Energy-dependent physical and biophysical constraints (2)

Summary: The mind does not exist in nature. It is a manifestation of how ecological variation must be linked to the creation of food energy-dependent pheromone-controlled ecological adaptations. Energy-dependent physical and biophysical constraints (1) The energy-dependent de novo creation of all receptors is biophysically constrained. See: Channel opening and gating mechanism in AMPA-subtype glutamate receptors This was reported as: Scientists capture first image of major brain receptor in action Defects in glutamate receptors, or the processes they mediate, are implicated…

Energy-dependent chirality (2)

See Energy-dependent chirality 2013 MicroRNA-based regulation of epithelial–hybrid–mesenchymal fate determination See also E. Ben-Jacob Ben-Jacob et al., have linked everything currently known about natural information processing from natural selection for energy-dependent codon optimality to healthy longevity and from virus-driven energy theft to mutations that cause cancer. See for comparison: LH Tsai Tsai laboratory Our primary goal is to elucidate the mechanisms underlying neurological disorders affecting learning & memory. The major research areas include age disorders, autism, and Alzheimer’s disease. 2012…

Life is energy-dependent task management (2)

See: Life is energy-dependent task management See also: New device detects bacteria and tests for antibiotic resistance When bacteria are caught, the device sends out three different signals to researchers. When bacteria is detected the cantilever’s mass changes, and it bends, explained Thomas Thundat, a professor in the Department of Chemical and Materials Engineering and the Canada Excellence Research Chair in Oil Sands Molecular Engineering. “So this gives us two signals: the mass change and the bending action.” By shining…

Chromatin: The structure of DNA

Update on Inflammation and Degenerative Brain Disease Excerpt: While mapping connections of neurons has become the holy grail of current neuroscience, it is clear that communication of neurons with many other types cells is, also, vitally important to every aspect of brain function. My comment: Understanding dementia was placed into the context of understanding how virus-driven energy theft alters the de novo creation of olfactory receptor genes and causes the loss of function that is linked to all pathology via…

Did Brain Atrophy Evolve?

Common Variants in ABCA7 and MSA46A are Associated with Cortical and Hippocampal Atrophy (Subscription required) Reported as: Two Alzheimer’s Risk Genes Linked to Brain Atrophy Excerpt: Using magnetic resonance imaging tools to measure brain size and genetic analysis, the researchers looked for associations between the genetic variants and atrophy in the cortical and hippocampal regions of the brain, which are established physical biomarkers of Alzheimer’s disease. My comment: Can anyone tell me how the genes that produce the proteins in…

pH, water, amino acids and protein folding

Solubilities of amino acids in water at various pH values under 298.15 K and Translational tuning optimizes nascent protein folding in cells link what is currently known about the biophysically constrained chemistry of nutrient-dependent RNA-mediated protein folding to cell type differentiation in all genera via conserved molecular mechanisms.  Mutations are linked from perturbed protein folding to pathology. See for example: From “Science Mission” 5/2/15 at 12 pm Water diffusion and neurodegenerative disease linked to Hydration water mobility is enhanced around tau…
