摘要: Aims. Abnormal regulation of autophagy participates in the development diabetic nephropathy. mTOR is most common negative regulator signaling pathway. FBW7 constitutes SCF (Skp1–Cullin1–F-box protein) recognition subunit E3 ubiquitin ligase, and a substrate that can be modified by ubiquitination degraded via proteasomes. In this study, we explored relationship between examined effects on occurrence nephropathy vitro. Materials Methods. We cultured mesangial cells induced high glucose vitro used rapamycin as specific inhibitor, performed gene overexpression, detected expression signal inflammatory factors WB, ELISA, RT-PCR, immunofluorescence. Results. High downregulate activate signal, which leads to diminished renal cells, well cytokines fibrotic factors. RAPA, specifically inhibitor mTOR, decrease inhibiting mTOR. Moreover, overexpression increase signal; at same time, were decreased cells. Conclusions. was glucose, ameliorate inflammation fibrosis.
