The use of normal adult liver hepatocytes in cell culture for biochemical, toxicological and pharmacological studies has been greatly limited owing to the loss of replicative capacity and differentiated liver function. This is contrary to the ability

Aberrant expression of Ki67, p53 and RARbeta are characteristic of many tumor types including those of the oral cavity. Chemopreventive agents may act by modulating their expression to more normal levels.The effects of 21 chemopreventive agents on th

Chronic exposure of hepatocytes to reactive nitrogen species (RNS) following liver injury and inflammation leads not only to functional and morphological alterations in the liver but also to degenerative liver diseases and hepatocellular carcinoma. P

Squamous cell carcinoma (SCC) of the oral cavity is a multistep process, progressing through a series of discrete, irreversible and complementary alterations in genes that control cell growth, death, and differentiation. In the premalignant state, th

In tumors, resistance to chemotherapeutic drugs that alkylate the O6 position of guanine correlates with the levels of the DNA repair protein, O6-alkylguanine DNA alkyltransferase (AGT). The expression of AGT gene in human breast tumors was evaluated

BACKGROUND: The overexpression or amplification of tumor suppressor and proto-oncogenes are important factors in the progression of breast cancer. Recent attention has focused on the cyclin genes, whose involvement in signal transduction pathways reg

6-Phenylhexyl isothiocyanate (PHITC) enhances esophageal tumorigenesis induced by the carcinogen N -nitrosomethylben-zylamine (NMBA) in rats while its shorter chain analog, phenethyl isothiocyanate (PEITC), inhibits NMBA-induced esophageal tumorigene

The capacity of a cell to repair damage is the first step in preventing the deleterious consequences of DNA structural alterations induced by the exposure to mutagenic carcinogens. Mammalian cells, having complex genetic organization, have evolved so

DNA excision repair was measured in cell cultures derived from human fetal brain, intestine, kidney, liver, and skin following ultraviolet (UV) irradiation and N-ethyl-N-nitrosourea (ENU) treatment. Cells in early passages were exposed to 5 or 10 J o
