What is the Origin of IGF-1 Response Profiling?

The term is derived from the specific peptide hormone IGF-1 and the clinical practice of response profiling, which emerged from advances in molecular diagnostics and personalized medicine in endocrinology. It focuses on the functional output of the somatotropic axis, moving beyond simple concentration measurements.

What is the Mechanism of IGF-1 Response Profiling?

IGF-1 is synthesized primarily in the liver in response to growth hormone and exerts its effects by binding to the IGF-1 receptor on target cells, activating the PI3K/Akt/mTOR pathway, which is central to protein synthesis and cell proliferation. Response profiling measures downstream effectors and binding protein levels (e.g., IGFBP-3) to determine the efficiency of this signaling cascade. A high-fidelity response indicates a robust anabolic capacity, which can be leveraged in recovery and tissue remodeling protocols.

IGF-1 Response Profiling

Meaning

A diagnostic and clinical procedure that assesses the individual’s specific cellular sensitivity and systemic reaction to Insulin-like Growth Factor 1 (IGF-1), a key mediator of growth hormone action. This profiling informs personalized therapeutic strategies aimed at maximizing anabolic and regenerative outcomes.
