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( p < 0.01 )。PA干预后,与高脂组中的GRP-78,FAT/CD36,FABP4 mRNA相比((4.36±0.32 vs.) 8.15 ± 0.35 );(( 1.00 ± 0.04 VS. 2.46 ± 0.08 );(( 2.88 ± 0.55 VS. 8.29 ± 0.52 ), p < 0.01 )和蛋白质(((( 3338.13 ± 333.15 VS. 4963.98 ± 277.29 );(( 1978.85 ± 124.24 VS. 2676.07 ± 100.64 );(( 3372.00 ± 219.84 VS. 6083.20 ± 284.70 ), 两个都 p < 0.01 )LR组的表达降低。GLUT4 mRNA的表达水平(((( 0.75 ± 0.04 VS. 0.34 ± 0.03 ), p < 0.01 )和蛋白质(((( 3443.71 ± 191.89 VS. 2137.79 ± 118.75 ), p < 0.01 ) 增加。 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-
