Effects of HgCl 2 and MeHgCl on C. elegans metallothionein expression. Wild-type nematodes were exposed to sub-toxicity (2.0 μM for HgCl2; 0.75 μM for MeHgCl ), low-toxicity (7.5 μM for HgCl2; 2.0 μM for MeHgCl), and high-toxicity (20 μM for HgCl2; 7.5 μM for MeHgCl) mercurial concentrations for 24 h. Dark bars, HgCl2; light bars, MeHgCl. Steady-state levels of mtl-1 and mtl-2 were measured using qRT-PCR. Results are displayed as mean log2 ± SEM. Significant differences (p < 0.05) relative to untreated C. elegans are designated with an asterisk.
