Figure 4. Effects of FLX on ER stress in the brain of PD rats. (A) Transcriptional levels of Bip/GRP78, CHOP and caspase-3 were measured by RT-qPCR, n=6. (B-C) Translational levels of Bip/GRP78, p-XBP1, XBP1, CHOP and procaspase-3 were detected using Western blot, n=6 each group. *P<0.05, **P<0.01 versus control group; # P <0.05, ##P<0.01 versus rotenone-treated group.
