Effect of Borreria hispida Extract on SIRT1, HIF-1α, ET-1 and VEGFR-2 Gene Expression in NRK-52E Cells Subjected to Glucotoxicity

Abstract

This study aimed to investigate the impact of Borreria hispida extract on gene expression in NRK-52E cells under conditions of glucotoxicity. Gene expression analysis was conducted using RT-PCR following the exposure of cultured NRK-52E cells to glucotoxic conditions and varying concentrations of Borreria hispida extract. The results demonstrated a dose-dependent increase in SIRT1 gene expression and a concomitant decrease in HIF-1λ, ET-1, and VEGFR-2 gene expressions upon treatment with Borreria hispida extract. Additionally, molecular docking studies suggested the potential inhibition of Rho-kinase as a mechanistic explanation for these effects. Borreria hispida extract may confer renoprotective benefits against glucotoxicity-induced cellular damage. The potential therapeutic utility of Borreria hispida extracts in managing renal complications associated with conditions such as diabetes. Furthermore, our docking studies shed light on the potential molecular mechanisms underlying the observed effects, suggesting interactions between phytochemicals present in Borreria hispida extract and the JNK-1 protein. These interactions may contribute to the augmentation of SIRT1 activity, further bolstering the extract's therapeutic utility in DKD.
