Figure 3. Enhanced Sin3A knockdown (KD) paraquat sensitivity is partially suppressed by glutathione. Survival of control (-RU486), SIN3 KD or GFP RNAi (+RU486) flies on 5 mM paraquat is indicated. For glutathione treatment, flies were placed on media containing 0.22mM glutathione for seven days prior to paraquat treament. Error bars represent standard error of the mean. A and B. SIN3 KD. C and D. GFP RNAi serves as an additional control. * p<0.01.
