ipamorelin effects on gh and igf-1 Insulin-like growth factor 1 (IGF-1): a growth hormone Nutrition, GH/IGF-1 signaling, and cancer

The de novo synthesis pathway (e.g., serine synthesis pathway, SSP) confers metabolic autonomy by enabling endogenous serine production, particularly under nutrient-replete conditions where SSP suffices to meet proliferative demands ( Metabolic plasticity serves as a hallmark of cancer cell adaptation to microenvironmental heterogeneity
