์์ฉ ๊ธฐ์ : Somatotropin binds to specific cell surface receptors in target tissues (liver, bone, muscle, adipose). * **Direct effects:** Stimulates lipolysis and inhibits glucose uptake, leading to increased blood glucose levels (diabetogenic effect). * **Indirect effects:** Mediated primarily through the stimulation of **Insulin-like Growth Factor-1 (IGF-1)** production in the liver. **GH โ Liver โ IGF-1 release โ Binds to IGF receptors โ Promotes cellular proliferation, linear bone growth (at open epiphyseal plates), and protein synthesis.**

Acute overdose is unlikely to cause severe clinical signs other than transient hypoglycemia followed by hyperglycemia. Chronic overdosage leads to **acromegaly** and **diabetes mellitus**.
