Effect of overexpression or knockdown of PAL31 in C6 on H 2 O 2 -induced toxicity. (A) Representative micrographs showing C6 overexpressing GFP or GFP-tagged PAL31 after being treated with H2O2 (0 ~ 1 mM) for 4 hours. (B) MTT assay in GFP- or GFP-PAL31-overexpressed C6 after H2O2 treatment showing significant difference (cytoprotective effect of PAL31) at 0.5 mM and 1 mM H2O2 treatment between C6/GFP and C6/PAL31 groups. The data in each dosage were analyzed by two-way ANOVA and Bonferroni post hoc test. *P < 0.05, GFP (+H2O2) compared to PAL31 (+H2O2), n = 4, at 0.5 mM and 1 mM. (C) Western blot analysis of pal31 siRNA-treated C6 showing knockdown of PAL31 expression by PAL31 silencer using 41.5 (lane1), 83 (lane2), and 166 (lane 3) picomole of pal31 siRNA or 332 picomole negative control. Actin works as a loading control. (D) MTT assay in Negative- or PAL31 silencer transfected C6 after H2O2 treatment showing significant difference at 1 mM H2O2 treatment between C6/Negative and C6/PAL31 siRNA groups. *P < 0.05, Negative (+H2O2) compared to PAL31 siRNA (+H2O2), n = 4.
