Hmgb1 Enhances Rage Expression Via 5-Lipoxygenase Signaling Leading To An Increase In Age-Mediated Proliferation Of Vascular Smooth Muscle Cells

      Background and Aims: Receptors for advanced glycation end-product (RAGE) play a pivotal role in the progression of vascular remodeling in the injured vasculatures. However, the precise mechanisms regulating RAGE expression in VSMCs is unclear. Given the importance of 5-lipoxygenase (5-LO)-derived mediators in vascular injury, this study aimed to determine RAGE expression in VSMCs exposed to HMGB1, and also investigated the role of 5-LO signaling in HMGB1-induced RAGE expression and AGE-induced VSMC proliferation.
