Effect of dietary cellulose on cell proliferation and progression of 1,2-dimethylhydrazine-induced colon carcinogenesis in rats.
The effects of different levels of dietary cellulose on colonic crypt mitotic activity and colon carcinogenesis were studied in 190 male Sprague-Dawley rats. Rats were divided into groups and fed a basal fiber-free diet supplemented with either 0, 5, or 15% pure cellulose (w/w), for periods of 10 weeks (initiation stage) or 32 weeks (promotional stage). Half of the rats in each group were given...
متن کاملChemopreventive effect of artesunate in 1,2-dimethylhydrazine-induced rat colon carcinogenesis
Artesunate (ART) is a semisynthetic derivative of artemisinin. Artemisinin and its derivatives have shown profound cytotoxicity and antitumor activity in addition to antimalarial activity in various studies. As the in vivo chemopreventive efficacy of ART in colon carcinogenesis has not been investigated so far, the aim of the current study was to study the chemopreventive effect of ART in 1,2-d...
متن کاملChemopreventive effect of 24R,25-dihydroxyvitamin D(3) in N, N'-dimethylhydrazine-induced rat colon carcinogenesis.
In this study we investigated the effects of 24R,25-dihydroxyvitamin D(3) [24R,25(OH)(2)D(3)] on N,N'-dimethylhydrazine (DMH)-induced rat colon carcinogenesis. For experiments 1 and 2, 50 F344 male, 6-week-old rats were divided into five groups in each experiment. Animals were given s.c. injections of DMH once a week for 4 weeks. Those in groups 1-5 were given 24R,25(OH)(2)D(3) in the diet (10,...
متن کاملEarly stages of 1,2-dimethylhydrazine-induced colon carcinogenesis suppress immune-regulated ion transport of mouse distal colon.
Genetic events, such as gene deletion, mutation, and amplification, are involved in the development and progression of colonic neoplasia. The importance of interactions between immune cells and neoplastic cells in influencing the pathogenesis of colon cancer is suggested by the clinical efficacy of levamisole, an immunostimulant, in the treatment of colon cancer and by the association of local ...
متن کاملThe dimethylhydrazine induced colorectal tumours in rat - experimental colorectal carcinogenesis
The beginnings of the first animal model appreciated for its macroscopic and histological similarity to human colorectal carcinoma (CRC) extend to 1963, when Laqueur discovered that rats fed cycasin, a plant product, developed intestinal cancer. The active substance was identified and soon a similar compound, methylazoxymethanol acetate (MAMA) was synthesized that was more effective than the na...
