It activates AMPK signaling (the same pathway activated by exercise and caloric restriction), improves insulin sensitivity, enhances glucose uptake by muscle tissue, and supports mitochondrial biogenesis
However, in the non-senescent control fibroblast model cultured in 10% FBS DMEM treated with or without FOXO4-DRI (25 M), no SA--gal-positive cells were observed both in keloid fibroblasts and in normal skin fibroblasts (Supplementary Fig
May Influence Pain and Stress Response Pathways Some studies suggest DSIP may interact with pathways involved in pain perception and stress response, making it relevant in neurobiological research focused on central nervous system adaptability and resilience
