Alpha 2-Heremans-Schmid (AHSG), also known as Fetuin-A, is a multifunctional serum protein predominantly synthesized in the liver. This glycoprotein plays crucial roles in regulating calcium and phosphate homeostasis by inhibiting mineralization processes and modulating cell signaling pathways. AHSG binds to various cellular receptors, including the TGF-β receptor and RAGE (Receptor for Advanced Glycation End products), impacting inflammatory responses, cell migration, and tissue repair. Its diverse biological functions make AHSG a valuable biomarker for diseases such as osteoporosis, diabetes, and cardiovascular conditions. Recent research highlights its potential applications in diagnostic assays for disease detection and therapeutic strategies for managing metabolic and inflammatory disorders. Additionally, AHSG's role in bone mineralization and vascular calcification positions it as a target for developing novel treatments for bone and cardiovascular diseases.
