Inhibition of cGAS-STING signaling pathway alleviates high glucose-induced mesothelial-mesenchymal transition in human peritoneal mesothelial cell line HMrSV5.

ABSTRACT: The mesothelial-mesenchymal transition (MMT) of peritoneal mesothelial cells is a critical factor contributing to the progression of peritoneal fibrosis. This study aimed to explore the effect of cGAS-STING signaling pathway on the MMT process in peritoneal mesothelial cells. The expressions of cGAS, STING, α-SMA, and Vimentin in HMrSV5 cells treated with high glucose were analyzed using WB. Subsequently, si-cGAS and the cGAS inhibitor RU.521 were employed to intervene in HMrSV5 cells. qPCR was utilized to evaluate the expression levels of genes involved in the cGAS-STING signaling pathway (cGAS, STING, IRF3, TBK1) and MMT-related genes (E-cadherin, Vimentin, α-SMA, TGF-β1). The protein expressions of the cGAS-STING signaling pathway and MMT-related proteins were detected by WB. The invasi
