What is the Origin of Anabolic Signaling Potency?

The term synthesizes concepts from receptor pharmacology, where ligand potency is defined, and endocrinology concerning the anabolic effects of hormones like IGF-1 or testosterone. It is a measure of molecular action within physiological systems.

What is the Mechanism of Anabolic Signaling Potency?

Potency is dictated by the affinity of the anabolic ligand for its cognate receptor and the subsequent signal transduction efficiency across the intracellular environment. Optimized pathways, often involving the mTOR cascade, lead to increased myofibrillar protein synthesis rates following activation.

Anabolic Signaling Potency

Meaning

This quantifies the efficiency of hormonal or pharmacological agents in initiating downstream molecular cascades that promote tissue accretion, primarily protein synthesis in muscle fibers. High potency indicates a greater effect at lower concentrations of the signaling molecule.
