Rosiglitazone reduces diabetes angiopathy by inhibiting mitochondrial dysfunction dependent on regulating HSP22 expression.

ABSTRACT: The effects of rosiglitazone (RSG) in patients with type 2 diabetes mellitus (T2DM) remain controversial. Here, we first used network pharmacology to identify the common targets of RSG in the treatment of diabetes angiopathy (DA). Enrichment analysis found that the common genes were involved in the inflammatory response, leukocyte cell-cell adhesion, mitochondrion organization and oxidative stress. Our previous research confirmed that heat shock protein 22 (HSP22) suppresses diabetes-induced endothelial activation and injury by inhibiting mitochondrial reactive oxygen species (mtROS) formation and dysfunction. We then constructed HSP22 knockout mice with T2DM to investigate whether RSG protected the vascular endothelium by upregulating HSP22. Our study suggested that RSG reduced vascular e
