Abstract

This study identifies the carbohydrate-responsive element-binding protein as the direct transcriptional activator of TXNIP in vascular smooth muscle cells under conditions of hyperglycemia. Aorta-specific TXNIP knockdown demonstrates therapeutic potential by alleviating arterial stiffness and attenuating atherosclerotic plaque in diabetic mice. Pharmacologic inhibition of TXNIP or activation of AKT ameliorates the senescent phenotype, highlighting a druggable pathway in diabetic vasculopathy.
