Paeoniflorin Regulates NEDD4L/STAT3 Pathway to Induce Ferroptosis in Human Glioma Cells

Figure 1

Treatment of paeoniflorin significantly increased NEDD4L expression in glioma cell lines U251 and U87. (a)-(b) U251 cells were treated with PF at indicated concentration for 24 hours, after which mRNA and protein levels of SYVN1, NEDD4L, CBL, and SOCS5 were determined by qPCR (a) and western blot (b). (c)-(d) U87 cells were treated with PF at indicated concentration for 24 hours, after which mRNA and protein levels of SYVN1, NEDD4L, CBL, and SOCS5 were determined by qPCR (c) and western blot (d). (e)-(f) U251 cells and U87 cells were treated with 10 mM PF for different times as indicated, after which mRNA and protein levels of NEDD4L were determined by qPCR (e) and western blot (f).
