Identification of causal genes and their effects on other biological determinants untangles the complexities of aging and Alzheimer's and can facilitate drug discovery for sustaining healthy aging and treating Alzheimer's.
PIE-1 engages SUMO to preserve the embryonic germline fate and also to promote the assembly of a MEP-1/Mi-2/HDA-1 chromatin remodeling complex required for inherited Argonaute-mediated gene silencing in the adult hermaphrodite germline.
In models of chronic migraine, neuronal complexity is diminished in head-pain processing regions but restored through HDAC6 inhibition, which increases tubulin acetylation and cytoskeletal flexibility, and CGRP receptor blockade.
Lack of OPA1 in BAT impairs its thermogenic activation and induces endoplasmic reticulum stress, while improving systemic metabolism and thermoregulation via ATF4-FGF21-dependent and -independent mechanisms.
Genetic analyses reveal that the tropism towards specific Kras driver mutations during urethane carcinogenesis appears to arise from the selection of an oncogenic mutation in normal cells that imparts a narrow window of signaling conducive for tumorigenesis.
Artificial selection for increased tibia length in mice made their skulls longer, narrower, and flatter, suggesting that even distant skeletal regions can evolve as correlated responses to selection acting locally.
