Journal ArticleDOI
Genetic and epigenetic mechanisms in metal carcinogenesis and cocarcinogenesis: nickel, arsenic, and chromium.
TL;DR: Overall, metal carcinogenesis appears to require the formation of specific metal complexes, chromosomal damage, and activation of signal transduction pathways promoting survival and expansion of genetically/epigenetically altered cells.
Journal ArticleDOI
Chromium in drinking water: sources, metabolism, and cancer risks.
TL;DR: Bioavailability results and kinetic considerations suggest that 10–20% of ingested low-dose Cr(VI) escapes human gastric inactivation, and the incompleteness of gastric detoxification argue against a threshold in low- dose extrapolation of cancer risk for ingested Cr( VI).
Journal ArticleDOI
Carcinogenic nickel silences gene expression by chromatin condensation and DNA methylation: a new model for epigenetic carcinogens.
Yong-Woo Lee,Catherine B. Klein,Biserka Kargacin,Konstantin Salnikow,Jun Kitahara,Karol Dowjat,Anatoly Zhitkovich,N T Christie,Max Costa +8 more
TL;DR: It is proposed that DNA condensation and methylation result in heterochromatinization of the gpt sequence with subsequent inheritance of the now silenced gene, which further supports the emerging theory that nickel is a human carcinogen that can alter gene expression by enhanced DNA methylation and compaction, rather than by mutagenic mechanisms.
Journal ArticleDOI
Depletion of Intracellular Ascorbate by the Carcinogenic Metals Nickel and Cobalt Results in the Induction of Hypoxic Stress
Konstantin Salnikow,Steven P. Donald,Richard K. Bruick,Anatoly Zhitkovich,James M. Phang,Kazimierz S. Kasprzak +5 more
TL;DR: It is suggested that the observed depletion of ascorbate by nickel( II) or cobalt(II) favors iron oxidation and thus inactivation of the enzyme, which is essential for maintaining iron in prolyl hydroxylases in the active iron(II] state.
