The effect of cysteine concentration and cysteine source [cysteine, methionine or 2-oxo-thiazolidine-4-carboxylate (OTC)] on the metabolism of [35S]cysteine was studied in isolated rat hepatocytes. Production of each of the major metabolites of cysteine (glutathione, sulfate, taurine) increased as cysteine or methionine, but not OTC, concentration in the medium was increased. At equimolar exoge...
Suppression by L-methionine of cell cycle progression in LNCaP and MCF-7 cells but not benign cells.
BACKGROUND/AIM Methionine inhibits proliferation of breast and prostate cancer cells. This study aimed to determine cell cycle effects of methionine and selectivity for cancer cells. MATERIALS AND METHODS MCF-7 (breast), LNCaP (prostate), and LS-174 (colon) cancer cells (wild-type p53), DU-145 (prostate) and SW480 (colon) cancer cells (mutated p53), and immortalized, non-tumorigenic MCF-10A (...
The mechanism of formation of the methyl group of methionine is of particular interest at the present time since the reaction may be studied in cell-free systems and is dependent on the direct participation of vitamin Bit. The reported systems for study of methionine biosynthesis in vitro have been derived from mammalian, avian, and bacterial sources (&lo). Serine and formaldehyde have been the...
