Beyond these examples, exercise also activates broader metabolic, oxidative stress, immune, and mechanotransduction programs, such as AMPK-PGC1 signaling [14,15,16], Nrf2-ARE antioxidant signaling [17], JAK-STAT immune signaling [18, 19], and mechanosensitive modules, including integrin-FAK-RhoA/ROCK signaling [20, 21], YAP/TAZ-Hippo signaling [22,23,24], and Piezo1-calcium signaling [25]
Disturbances in the intestinal endothelium, lymphoid atrophy, gut dysbiosis, and elevated inflammatory metabolites (TNF, specific pteridines, IL-1, IL-6 and IL-12, fecal calgranulin and myeloperoxidase) further compromise intestinal function [51, 106, 110,111,112] SAM-induced inflammation further inhibits micronutrient uptake, creating a downward spiral in SAM severity and increased morbidity and mortality [104, 113]
