Data expressed as mean ± SEM (N = 7). Letter “a” indicates significantly higher compared with the wild-type control group; “b” indicates significantly higher compared with Nep-null control group; and “c” indicates significant difference between wild-type and Nep-null mice with the same dose of DEP (P < 0.05). The DEP exposure was meant to approximate an accumulated dose of 7 days.
