Expression of MT protein in cells exposed to Pb. WT cells were treated with 200μM Pb for 0–48 h. Cellular MT protein levels were measured by Western blot analysis. Blots were analyzed by scanning densitometry and are expressed as a protein level. Data are presented as the mean ± SEM, n = 3. An asterisk (*) indicates a significant (p < 0.05) difference from untreated cells. The arrows indicate the approximate time Pb-induced IBs become visible by light microscope. MT protein in MT-null cells was very low to undetectable regardless of treatment (not shown).
