N-Nitrosopyrrolidine (NPYR) is a well-established hepatocarcinogen in the rat. NPYR requires metabolic activation by cytochrome P450-catalyzed alpha-hydroxylation to express its carcinogenic activity. This produces alpha-hydroxyNPYR (2), which spontaneously ring opens to 4-oxobutanediazohydroxide (4), a highly reactive intermediate, which may itself

The aim of this study was to investigate the protective effect of isothiocyanates towards N-nitrosamine-induced DNA damage in the single-cell gel electrophoresis (SCGE)/HepG2 assay. None of the isothiocyanates (ITCs) concentrations tested in the presence or absence of formamidopyrimidine-DNA glycosylase (Fpg)

N-Nitrosopyrrolidine (NPYR) is a hepatocarcinogen in rats. It is metabolically activated by cytochrome P450 enzymes in the liver leading to the formation of 4-oxobutanediazohydroxide (4) and related intermediates that react with DNA to form adducts. Because DNA adducts are thought

DNA Damage and Repair

DNA damage and repair mechanism is vital for maintaining DNA integrity. Damage to cellular DNA is involved in mutagenesis, the development of cancer among others.

Carcinogenesis and Epigenetics

Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.
