Figure 6. Impact of Asc and GSH on DPC formation in A549 cells.

Figure 6

All Cr(VI) exposures were for 3 hr in serum-free medium. Data are means±SD. (A) DPC levels in cells with and without pretreatment with 0.1 mM BSO for 24 hr. DPC were measured either immediately (left panel) or 18 hr after Cr(VI) treatments (right panel). (B) Formation of DPC in control and 1 mM Asc-preloaded cells. (C) Cr accumulation by A549 cells with and without Asc-preloading.
