Figure 2. Oxidative stress related gene induction by racemate and enantiomers of o,p’-DDT.

Figure 2

The relative expression of anti-oxidative related genes encoding superoxide dismutase (SOD1 and SOD2) and heat shock protein (HSP) genes in response to racemate and enantiomers of o,p’-DDT. The asterisk denoted p<0.05 relative to the negative control. Different letters above adjacent bars indicate a significant difference (p<0.05) between individual enantiomers or between an enantiomer and racemate, while the same letter indicates no significant difference.
