Myostatin

Myostatin is a protein that functions by inhibiting muscle growth through the regulation of muscle cell proliferation and differentiation. Interest in Myostatin started around the late 1990s when researchers discovered its potential role in muscle development and wasting conditions. A notable biological detail is Myostatin's presence in skeletal muscles, where it acts as a critical regulator of muscle mass. Today, it is primarily studied for its effects on:

• Muscle growth and development
• Muscle wasting disorders
• Skeletal muscle regulation
