Anabolic Signaling

Meaning

Anabolic signaling refers to the biochemical pathways responsible for the synthesis of complex molecules from simpler precursors, resulting in growth or accretion of tissue mass. Within endocrinology, this primarily describes the signaling cascades initiated by anabolic hormones such as insulin, IGF-1, and testosterone. We evaluate these processes to understand muscle protein synthesis rates and overall tissue building capacity. Maintaining robust anabolic signaling is critical for recovery and lean mass preservation.
