Abstract:
The ARHGEF (Rho guanine nucleotide exchange factor) family acts as a key upstream regulator of Rho GTPases, including RhoA, Rac1, and Cdc42. It plays critical roles in cytoskeletal remodeling, cell migration, vascular tone regulation, and inflammatory responses. Recent studies have shown that dysregulated ARHGEF activity contributes to cardiovascular diseases such as atherosclerosis, hypertension, cardiac hypertrophy, fibrosis, and myocardial ischemia/reperfusion injury. However, the functions of ARHGEFs in specific cell types and their overall signaling mechanisms in the cardiovascular system remain poorly understood. This review provides a comprehensive framework of current progress in understanding the molecular mechanisms underlying ARHGEF-mediated regulation in endothelial dysfunction, vascular remodeling, myocardial fibrosis, and ischemia/reperfusion injury. It also highlights potential pharmacological strategies that target the ARHGEF and Rho GTPase signaling axis for precise therapeutic intervention. By integrating molecular, cellular, and translational research, this work offers a conceptual framework for ARHGEF-driven signaling in cardiovascular diseases, and offers new insights for future drug development.
