目的。培养L6细胞以探索利拉格林(LR)改善胰岛素抵抗的可能机制。
方法。细胞分为5组 - 对照,高脂,10 nmol/l

0.6
mmol/L PA (1000LR). CCK-8 method to detect cell viability, GPO-PAP enzymatic method to detect intracellular triglyceride content, and reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) and western blotting methods to detect fatty acid translocase CD36 (FAT/CD36) and fatty acid binding protein 4 (FABP4) in L6 cells, glucose-regulated protein 78 (GRP78), glucose transporter 4 (GLUT4) expression at the mRNA and protein levels, respectively, were performed.
结果。我们发现PA干预24小时后,细胞活力显着降低。LR组的细胞活力高于高脂组(

结论。因此,我们得出的结论是,LR可以逆转PA诱导的细胞失活和脂质沉积,这可能与GRP-78,FAT/CD36,FABP4,GLUT4和其他因素的变化有关。SN -2314-6133 UR -https://doi.org/10.1155/2022/6237405 DO -10.1155/2022/2022/6237405 JF -BIOMED Research International PB- Hindawi KW -er -er- ER-
