GAS treatment attenuated the increased expression of KLK8 in the diabetic myocardium.  A Immunohistochemical staining and quantification of elevated levels of KLK8 in the myocardium. B Immunoblot of KLK8 in the heart. C The level of expression of KLK8 mRNA in the heart. D Chemical structural formula of GAS. E-F. Molecular docking data of GAS with the KLK8 protein was analyzed using the automated docking software. E Two-dimensional interaction. F Three-dimensional interaction. G Cellular thermal transfer assay (CETSA) and immunoblotting analysis were performed with cells treated with 5 µM GAS and DMSO at different temperatures. The data are expressed as the mean ± SEM of three or more independent experiments; *p  < 0.05, **p  < 0.01, ***p  < 0.001, and ****p  < 0.0001.
