چکیده انگلیسی
MAX interactor 1 (Mxi1) proteins are c-myc antagonists that primarily exert their biological functions by inhibiting Myc-dependent gene transcription. In this study, Mxi1â/â mice were used to generate a model of mesangial proliferative glomerulonephritis for the first time. In the present study, we demonstrated that Mxi1â/â mice exhibited a more typical and severe pathological phenotype, which was displayed primarily as a noticeable dissolution phenotype with a higher proportion of apoptotic cells and higher chemokine CXCL10 expression during the early days of modeling, compared with wild-type mice. Additionally, we determined that IRF3-mediated TLR4 signaling was likely involved in regulating CXCL10 expression, which might participate in the mesangial dissolution process. We also found increases in CXCL10 expression, caspase 3 activation, and the proportion of apoptotic cells when Mxi1 expression was inhibited in mouse mesangial cells. Furthermore, the proportion of apoptotic cells decreased after inhibiting CXCL10 expression. Therefore, we concluded that the mesangial cell apoptosis observed in this mesangial proliferative glomerulonephritis model was related to CXCL10 expression induced by Mxi1 inactivation. This finding provides a new theoretical basis for the mechanism of mesangial proliferative glomerulonephritis progression and reveals potential intervention targets for the early treatment of this disease.
