Chronic engagement of Natural killer cell inhibitory receptors by MHC-I molecules maintains a high activity of the mTOR pathway allowing subsequent amplification of signaling through activating receptors upon acute stimulation.
Transcriptomic analysis using a novel information-based network entropy approach provides mechanistic insights into the ability of Klotho to successfully ameliorate age-related sarcopenia in old mice, but not oldest-old mice.
The melanocortin-4 receptor knockout mouse exhibits a cardiomyopathy syndrome, which raises concerns about cardiovascular function in patients with the similar loss of function mutations, and perhaps even in the 1 in 1500 patients with heterozygous loss of the gene.
A muscle-derived signaling molecule suppresses excessive accumulation of lipids in the Drosophila adipose tissue by activating the Pi3K/Akt/mTOR signaling cascade in the Drosophila hepatocyte-like cells.
Lipocalin-2 is a strong predictor of hunger scores, reflects an anti-obesity response that is deregulated in severely obese subjects, and exerts an anorexigenic function with a conserved interspecies mechanism.
LRRC8A is an essential component of a mechanoresponsive ion channel signaling complex that tunes skeletal muscle differentiation, muscle cell size, function and metabolic pathways to regulate adiposity and systemic glycemia.
