Effect of glibenclamide on N-nitroso-N-methylurea-induced mammary tumors in diabetic and nondiabetic rats.
The objective of this study was to evaluate the antitumor effect of glibenclamide (Gli) alone or in combination with tamoxifen (Tam) on experimental mammary tumors induced by N-nitroso-N-methylurea (NMU) in nondiabetic and diabetic rats. For experimental diabetes induction, Sprague-Dawley rats were injected with streptozotocin (STZ) on the second day of life. For experimental mammary tumor indu...
متن کاملEffect of tamoxifen on preneoplastic cell proliferation in N-nitroso-N-methylurea-induced mammary carcinogenesis.
N-Nitroso-N-methylurea (NMU) is an effective carcinogen for the induction of mammary carcinoma in the rat. Tamoxifen (TAM), used as a chemopreventive agent to reduce tumor incidence, has been well studied using this model. We have utilized the rat mammary carcinoma model to assess the effect of TAM on preneoplastic changes. Fifty-day-old virgin female Sprague-Dawley rats were randomized by weig...
متن کاملInvestigation of p53 and p27 expressions in the N-nitroso-N-methylureainduced breast cancer in female Wistar Albino rats
Introduction: N-nitroso-N-methylurea (NMU) is a carcinogen from nitrosamines family, which has been used to induce breast cancer in rodents. This model of breast cancer is very similar to the estrogen dependent breast cancer in human. As a continuation of our recent works, in the present study, the expressions of both p53 and p27 were investigated in NMU-induced breast cancer in Wistar Albin...
متن کاملHepatocarcinogenic effects of N-nitroso-N-methylurea in guinea pigs.
Intragastric administration of N-nitroso-N-methylurea to strain 13 male guinea pigs, at a weekly dosage of 7.5 mg/kg for 15 weeks and then twice weekly for a subsequent 15 weeks, induced high toxicity, as evidenced by weight loss and mortality and a high incidence of malignant neoplasms, over a total observational period of 40 weeks. The neoplasms included hepatic angiosarcomas, cholangiocarcin...
متن کاملEffect of rosiglitazone on N-nitroso-N-methylurea-induced mammary tumors in rat.
The objective of this study was to evaluate the in vivo antitumor action of rosiglitazone (Rosi) alone or in combination with tamoxifen (Tam) on experimental mammary tumors induced by N-nitroso-N-methylurea (NMU) in Sprague-Dawley rats. Animals bearing mammary tumors were treated with 0.06 mg/kg/day or 0.12 mg/kg/day of Rosi orally, 1 mg/kg/day of Tam s.c., or with the combined treatment (Rosi+...
