Which of the following actions of GH is mediated by IGF-1?

Antilipolysis. ***Antilipolysis*** * **Insulin-like growth factor 1 (IGF-1)**, stimulated by GH, plays a role in reducing **lipolysis** indirectly. * IGF-1 promotes **anabolic processes** and nutrient storage, which can lead to decreased fat breakdown. *Na+ retention* * **Na+ retention** is more directly influenced by hormones like **aldosterone** and **ADH**, not IGF-1. * While GH can exert some influence on fluid and electrolyte balance, this specific action is not primarily mediated by IGF-1. *decreases insulin* * IGF-1 and GH generally tend to **increase insulin sensitivity** in some tissues or antagonize insulin effects indirectly. * IGF-1's primary metabolic role is not to decrease insulin itself directly. *Lipolysis* * **Growth hormone (GH)** directly promotes **lipolysis**, breaking down fat for energy. * However, the question specifically asks for actions mediated by **IGF-1**, which has an opposite, antilipolytic effect.
