“…Both the cadmium and chromium are present in the contaminated aquatic ecosystems and pose risk to the aquatic organisms. At present, few information is available in the literature that show the sensitivity of two different algal species (prokaryote and eukaryotic) to cadmium and chromium (Thompson et al 2002), as well as their capacity for metal accumulation.…”

“…chromium is present in an insoluble form (Apte et al, 2005). Regardless of the potential oxidation of chromium in the environment, the trivalent form of this metal has also been noted as toxic to microorganisms (Thompson et al, 2002;Pereira et al, 2005).…”

“…Third, a large fraction of SO 4 2− transport mutants do not display Cr-resistant phenotypes (Esko et al, 1986). Fourth, roles for intracellular Cr-binding proteins have been implicated in cyanobacteria (Thompson et al, 2002) and some animal cells (Lu & Yang, 1995). Thus, the combined observations suggest that the genetic causes and consequences of Cr-resistant states remain to be unraveled.…”

CrO3 is cytotoxic for human epithelial 293 kidney cells over a narrow concentration range of approximately 2-8 microM (D50 approximately 3.0 microM); significantly greater toxicity is observed in clonogenic assays (D50 approximately 0.1-1.0 microM). Survival of a small fraction of cells (< or = 0.1%) at CrO3 concentrations between 10(-5) to 10(-3) M, and first-order kinetics of cytotoxicity, rationalized the derivation of a new panel of transformed human epithelial cell lines resistant to cytotoxic concentrations of CrO3 over the range of 5-100 microM. Wild-type and Cr-resistant 293 cell lines display similar morphology under phase microscopy, but wild-type cells grow faster and reach stationary phase sooner than Cr-resistant cells. The Cr-resistant phenotype is stable, and it is specific, since Cr-resistant cells are killed by NiSO4 or by CdCl2 at concentrations equivalent to those that kill wild-type cells. Toxicity analysis curves subjected to target theory suggest that the Cr-resistant cell lines have fewer Cr-sensitive "targets" and have undergone a "loss of function" compared to wild-type cells. This loss of function may be related to significantly lower rates of uptake of Na2(51)CrO4,which correlate inversely with CrO3 concentrations used for the selection and maintenance of the Cr-resistant lines, and to reduced levels of an approximately 96-kDa protein in comparison to wild-type cells. This new panel of Cr-resistant transformed human epithelial kidney cell lines will be useful in comparative studies of genetic resistance and sensitivity to human Cr(VI) toxicity, sulfate transport, and growth control differences between wild-type and Cr-resistant cells.
