chemopreventive effect of curcumin, a naturally occurring anti-inflammatory agent, during the promotion/progression stages of colon cancer.curcumin, derived from the rhizome of curcuma longa l. and having both antioxidant and anti-inflammatory properties, inhibits chemically induced carcinogenesis in the skin, forestomach, and colon when it is administered during initiation and/or postinitiation stages. this study was designed to investigate the chemopreventive action of curcumin when it is administered (late in the premalignant stage) during the promotion/progression stage of colon carcinogenesis in male f344 rats. we also studied ...19999973206
antitumor activity of curcumin is mediated through the induction of apoptosis in ak-5 tumor cells.curcumin, the yellow pigment of turmeric (curcuma longa), used commonly as a spice, has been shown to possess anticarcinogenic activity. curcumin inhibited ak-5 tumor growth and induced apoptosis in ak-5 cells. curcumin induced apoptosis is mediated through the activation of caspase-3, which is specifically inhibited by the tetrapeptide ac-devd-cho. in addition, curcumin induced tumor cell death is caused through the generation of reactive oxygen intermediates which is inhibited by n-acetyl-l-cy ...199910069393
modulation of radioresponse of glyoxalase system by curcumin.human beings have been exposed to radiation for many years. it is quite possible that antioxidant phytochemicals consumed in their diet might be providing a variable degree of radioprotection. however, their radiomodifying ability is not well understood. in the present work, curcumin (diferuloyl methane), a phytochemical present in the rhizome of curcuma longa linn. has been examined for its radioprotective property using the glyoxalase system which is vital for various biological functions. cur ...199910075116
dietary curcumin with cisplatin administration modulates tumour marker indices in experimental fibrosarcoma.curcumin, the active constituent of curcuma longa, which itself possesses antitumour activity against experimental tumours, enhances the antitumour effect of the widely used anticancer drug cisplatin, when used in combination against fibrosarcoma. tumour marker enzymes such as aminotransferases, lactate dehydrogenase, gamma-glutamyl transpeptidase, alkaline phosphatase, 5'-nucleotidase were analysed in liver and kidney homogenates of experimental rats. all these enzyme activities were markedly i ...199910094841
