NR5A2 (Nuclear Receptor Subfamily 5 Group A Member 2): NR5A2, also known as LRH-1, is a nuclear receptor that regulates key processes such as cholesterol balance, bile acid production, and steroid hormone synthesis. It also plays an important role in pancreatic development and function. Altered NR5A2 activity has been linked to metabolic disorders and several cancers, especially those affecting the gastrointestinal tract.
