Where it's most often discussed: Tissue repair and recovery models (especially tendons/ligaments and muscle) Wound healing and regenerative signaling Gut integrity and inflammation-related pathways Where it's not firmly established: Extensive, rigorous human studies designed to measure fat loss outcomes (fat mass, waist circumference, body fat percentage) That distinction matters
This makes sense, because when a hair strand isnt growing, there are no new regions of that hair requiring pigmentation
Persistent ischemia directly induces mitochondrial dysfunction in intestinal epithelial cells, exacerbating oxidative stress and impairing ATP synthesis
Nitric oxide promotes smooth muscle relaxation, and imbalanced NO signaling contributes to sphincter dysfunction
MET activation is thus involved in brain plasticity, as suggested by the fact that HGF administration on hippocampal slices enhances the phosphorylation of the glutamatergic NMDA receptor subunit GluN1, augments the NMDA-mediated currents, and increases the amplitude of long-term potentiation (LTP) induced by elevated neuronal activity (Akimoto et al., 2004)
