Cadmium, carcinogen, co-carcinogen and anti carcinogen [PDF]
Indian Journal of Clinical Biochemistry, 2001 As a stress agent, inducing apoptosis and blocking it, Cd can have both helpful and harmful effects. The atmosphere is a thin envelope which makes the worid a global village. Cd is the most toxic metal in air. As both the first and second messenger of the stress response, it is synergistically toxic with all other stressors, including many other ...

Oxidative Stress in the Carcinogenicity of Chemical Carcinogens [PDF]
Cancers, 2013 This review highlights several in vivo studies utilizing non-genotoxic and genotoxic chemical carcinogens, and the mechanisms of their high and low dose carcinogenicities with respect to formation of oxidative stress. Here, we survey the examples and discuss possible mechanisms of hormetic effects with cytochrome P450 inducers, such as phenobarbital, a-

Epidemiology, Biostatistics, and Public Health, 2022 Millions of people have tattoos. The systemic effects of tattoo colorants (TCs) are mostly unknown. Several tattoos are on the market, which contain carcinogenic compounds such as poly aromatic hydrocarbons compounds or carcinogenic aromatic amines.

Carcinogenesis, 2018 Cytochrome P450 enzyme systems have been widely used in vitro to determine the pathways of activation of procarcinogens, but paradoxically, these same enzymes can play a more predominant role in carcinogen detoxification in vivo.

Threshold in Carcinogenicity of Genotoxic Carcinogens [PDF]
Journal of Carcinogenesis & Mutagenesis, 2014 Nowadays the idea of threshold in the carcinogenicity of chemical carcinogens has attracted interest in the field of carcinogenesis. With genotoxic agents there is considerable experimental evidence in support of the idea. Here, we report on the low dose carcinogenicity in rats observed with heterocyclic amines contained in cooked food, 2-amino-3,8 ...
