1 Western blot analysis showed that UA promoted the phosphorylation of PERK and eIF2alpha; this was followed by the upregulation of the downstream protein CHOP, implying the involvement of the ER stress-mediated PERK/eIF2alpha/CHOP pathway in glioma cells. ursolic acid eukaryotic translation initiation factor 2 alpha kinase 3 Homo sapiens
2 Western blot analysis showed that UA promoted the phosphorylation of PERK and eIF2alpha; this was followed by the upregulation of the downstream protein CHOP, implying the involvement of the ER stress-mediated PERK/eIF2alpha/CHOP pathway in glioma cells. ursolic acid eukaryotic translation initiation factor 2 alpha kinase 3 Homo sapiens
3 Furthermore, TUDCA and the silencing of either PERK or IRE1alpha partially blocked the UA-induced accumulation of LC3-II, suggesting that ER stress precedes the process of autophagy. ursolic acid eukaryotic translation initiation factor 2 alpha kinase 3 Homo sapiens
