MDCK cells were cultured for 6-24 hr in vitro in various concentrations (0.1-100 M) of HgCl2, and the markers of apoptosis or cell death were assayed, including DNA fragmentation, caspase-3 activity andwestern blotting of cytochrome c.

The cytochrome c oxidase activities of strains AP19-3 and ATCC 23270 were completely inhibited by 1 muM and 5 muM of mercuric chloride respectively.

Since mitochondrial dysfunction and the development of a permeability transition may result in the release of cytochrome c, a factor that promotes apoptosis, we assessed the abilities of both species of mercury to induce the translocation of cytochrome c from mitochondria to the cytosol.

The release of cytochrome c (Cyt c) from mitochondria into the cytosol, which is an initiator of the activation of caspase cascades, was also observed in HgCl (2)-treated HL-60 cells.

We have previously shown that methyl mercuric chloride (MeHgCl) is a potent human T-cell apoptogen; moreover, mitochondria appear to be a target organelle for the induction of cell death.
We next observed the release of cytochrome c from mitochondria into the cytosol; significant translocation was noted between 4 and 8 h following treatment with mercury.
