Dapagliflozin inhibits TGF-β-induced transdifferentiation of valvular interstitial cells and mitral valvular degeneration.

ABSTRACT: Myxomatous mitral valve (MV) disease (MMVD) is a common cardiac condition in humans and dogs. Currently, no therapeutic agent is available for MMVD that can prevent MV degeneration. Transforming growth factor (TGF)-β-induced transdifferentiation of valvular interstitial cells (VICs) is a key process in MV degeneration. Dapagliflozin is used to treat type 2 diabetes, and it alleviates cardiac and renal fibrosis by inhibiting the TGF-β signaling pathway. In this study, we investigated the effect of dapagliflozin on TGF-β-induced transdifferentiation of VICs and MV degeneration in rats. Protein expression levels and contractile forces generated by VICs were determined using western blotting and a collagen gel contraction assay, respectively. Structural changes of the MV were detected using hi
