Genetic and DNA-methylation changes induced by potassium dichromate in Brassica napus L.

Massimo Labra et al.

Chemosphere, 54(8), 1049-1058 (2003-12-11)

This study evaluated genetic and DNA methylation alteration induced by potassium dichromate in Brassica napus L. plants. Amplified fragment length polymorphism (AFLP) and selective amplification of polymorphic loci (SAMPL) tests revealed dose-related increases in sequence alterations in plantlets exposed to

Curcumin prevents Cr(VI)-induced renal oxidant damage by a mitochondrial pathway.

Eduardo Molina-Jijón et al.

Free radical biology & medicine, 51(8), 1543-1557 (2011-08-16)

We report the role of mitochondria in the protective effects of curcumin, a well-known direct and indirect antioxidant, against the renal oxidant damage induced by the hexavalent chromium [Cr(VI)] compound potassium dichromate (K(2)Cr(2)O(7)) in rats. Curcumin was given daily by
