Effect 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 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+...
متن کاملEffect 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 کاملProlactin, TNF alpha and nitric oxide expression in nitroso-N-methylurea-induced-mammary tumours
BACKGROUND The N-Nitrosomethylurea breast cancer model induced in rats is used for the study of carcinogenesis in mammary cancer, prostate, pancreas, etc. This model is very similar to human neoplastic disease. METHODS The present experimental study was designed to assess whether metoclopramide administration has any effect on development of MNU-induced tumours, and evaluate the treatment of ...
متن کاملA rodent model for Wilms tumors: embryonal kidney neoplasms induced by N-nitroso-N'-methylurea.
Embryonal kidney cell tumors develop in rats given the alkylating agent N-nitroso-N'-methylurea as neonates. These tumors resemble the childhood Wilms tumors in their histopathology. Deletions and mutations in the Wilms tumor suppressor gene, WT1, are present in up to 6% of childhood nephroblastomas. To investigate the role of WT1 in rat kidney tumorigenesis, we studied the genetic alterations ...
