Figure 1.

Expression of metallothionein in lung tissues. Lung tissues were harvested from wildtype (WT) or MT-1 and -2 gene knockout (MT-KO) mice, and total RNA was extracted from these tissues. The resulting samples were subjected to real-time RT-PCR performed with a specific primer set for each gene. Values were normalized to Gapdh and are expressed relative to the WT. Values are the mean ± S.E.M.; # p < 0.05 (#, vs. WT). The experiments that produced the data shown in this figure were performed at least twice.
