Fig. 8From: Simultaneous exposure to vinylcyclohexene and methylmercury in Drosophila melanogaster: biochemical and molecular analysesExpression of the genes encoding Nrf2 and Keap1. mRNA levels of Nrf2 in the head (a) and body (b), as well as, Keap 1 in the head (c) and body (d) of D. melanogaster after exposure and coexposure to VCH and MeHg+ for three days. Data are expressed as the mean ± standard error. Results were analyzed by paired t-test and were considered significantly different when p < 0.05.Back to article page
