HIF1A overexpression promotes osteoblast differentiation through activation of autophagy to alleviate osteoporosis

Abstract excerpt

Objective Osteoporosis (OP) is a systemic skeletal disease that increases the risk of fractures by weaking bone. Hypoxia-inducible factor-1α (HIF-1α) plays a crucial role in osteogenesis and osteoblastic differentiation. The purpose of this study is to examine the underlying mechanism of HIF-1α overexpression and its impact on osteoblast development. Methods First, we used the autophagy inhibitor 3-MA in...
