What is the Origin of IGF-1 Axis Tuning?

The name references the Insulin-like Growth Factor 1 (IGF-1) axis, the primary mediator of GH's peripheral effects, combined with 'Tuning,' suggesting fine-adjustment of this complex system. This originates from growth biology and endocrinology.

What is the Mechanism of IGF-1 Axis Tuning?

The primary mechanism involves ensuring adequate hepatic GH receptor expression and downstream signaling to synthesize IGF-1, which then mediates most of GH's anabolic actions, including protein synthesis and cell proliferation. Nutritional sufficiency, particularly adequate protein intake and insulin signaling, provides the necessary substrate and permissive environment for this axis to function optimally. Tuning involves assessing factors that might block this signal, such as excessive insulin resistance or insufficient receptor availability.

IGF-1 Axis Tuning

Meaning

IGF-1 Axis Tuning describes the clinical optimization of the signaling cascade involving Growth Hormone (GH) and Insulin-like Growth Factor 1 (IGF-1) to promote tissue repair, growth, and metabolic regulation. This tuning ensures that the pituitary’s GH release translates effectively into peripheral IGF-1 action at the cellular level. We seek an optimal anabolic and reparative environment.
