Aim To investigate the effect of TRPC5 gene on the inflammation of cliabetie cardiomyopathy.Methods The biological functions of TRPC5 and the correlation between TRPC5 gene and other genes were analyzed by bioinformatics.Studies were performed in TRPC5 knockout ( TRPC5 ) and C57 mice.Mice were randomly divided into blank control and T2DM model groups, and the model was established by intraperitoneal injection of STZ (n = 10).The myocardial injury was detected by HE and Masson staining.Hie level of serum IL-1(3, IL-2, IL-6, IFN-7 and creatine kinase was examined by ELISA.Gene and protein expressions of IL-1(3, IL-2, IL-6 and TRPC5 were analysed by RT-PCR and Western blot respectively.Results By constructing the PPI network and analyses.the TRPC5 gene was identified to internet with a variety inflammatory genes and involved in immunity.The result of pathologieal section showed less myocardial damage and infiltrated immune cells in TRPC5 mice than in C57BL/6J mice.RT-PCR and serum results showed a lower expression of inflammatory factors in myocardium and serum obtained from TRPC5 model mice than in those obtained from C57BL/6J model mice.Conclusions TRPC5 participates in the development of dilated cardiomyopathy by regulating cardio- myocyte inflammation.
