Figure 3: Expression of genes encoding antioxidative enzymes in the liver.

mRNA levels of Homx1, Nqo1, Gclc, Gclm, Gss and Gr in the liver in B6 (closed bars) and 129 (open bars) mice at the indicated intervals after arsenic challenge. Values are expressed as mean + SD. *p < 0.05, compared with vehicle (Veh) of the same strain; #p < 0.05, compared with time-matched B6 mice. n = 5–6.
