Figure 8. The effect of PTGR1 siRNA knockdown on Nrf2 protection against 4-HNE.

Figure 8

Vehicle or tBHQ treated astrocytes were pretreated with A) non-targeting siRNA (siNT) or B) prostaglandin reductase-1 siRNA (siPTGR1). 4-HNE toxicity curves were performed as indicated. Cell viability was determined by MTS. Statistics were performed using 2-way ANOVA, * indicates p<0.01.
