The growth hormone and IGF-1 axis: what research on it actually examines

Published 9 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Growth hormone released from the pituitary acts on target tissues directly and also induces production of IGF-1, largely in the liver. Because much of the downstream effect runs through IGF-1, the two are studied as a single axis rather than independently.

Two effects, one axis

Growth hormone binds its receptor and produces direct effects on target cells. It also stimulates hepatic IGF-1 production, and circulating IGF-1 acts on its own receptor across many tissues.

Separating the two contributions is a long-standing problem in the field, because an intervention that raises growth hormone raises IGF-1 as well. Much of the experimental design in this area exists to tease them apart.

Why IGF-1 is the convenient measurement

Growth hormone is released in pulses, so a single blood measurement says little — it depends entirely on where in the pulse the sample was taken. IGF-1 is far more stable in circulation and integrates that pulsatility over time.

That is why IGF-1 induction is the common readout in growth-axis research. It is a practical proxy for an input that is awkward to measure directly, not an independent measure of a separate thing.

Where the research sits

Published work examines receptor signalling, IGF-1 induction, body-composition and metabolic models. Somatropin also appears widely as a reference material in analytical work, because it is among the best-characterised recombinant proteins available.
