Urinary bladder tumors induced by N-butyl-N-(4-hydroxybutyl)nitrosamine in dogs.
Clinicopathological, radiological, and histological studies were performed on urinary bladder neoplasia induced by N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) in five adult beagle dogs and in ten adult mongrel dogs. Tumors of the urinary bladder developed in dogs given various daily doses of BBN p.o. for different periods. The latent period of tumor induction was 4 years in dogs receiving a dai...
متن کاملKnockout of phospholipase Cε attenuates N-butyl-N-(4-hydroxybutyl) nitrosamine-induced bladder tumorigenesis
Bladder cancer frequently shows mutational activation of the oncogene Ras, which is associated with bladder carcinogenesis. However, the signaling pathway downstream of Ras remains to be fully elucidated. N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) is able to induce bladder cancer by driving the clonal expansion of initiated cells carrying the activated form of Ras. Phospholipase Cε (PLCε) is ...
متن کاملComparative proteomic analyses of urine from rat urothelial carcinoma chemically induced by exposure to N-butyl-N-(4-hydroxybutyl)-nitrosamine.
Bladder cancer is estimated to be the ninth most common malignancy with a high rate of recurrence and progression despite therapy, early diagnosis being crucial for timely intervention. Using a well-established animal model of urothelial carcinoma, we performed a comprehensive analysis of urine proteome profile from healthy animals and animals with urothelial carcinoma at two time-points of dis...
متن کاملEffects of promoters on N-butyl-N-(4-hydroxybutyl)nitrosamine-induced urinary bladder carcinogenesis in the rat.
It has been shown that the occurrence of the preneoplastic lesion, papillary or nodular hyperplasia (PN hyperplasia) in rat urinary bladder induced by carcinogens is correlated with that of cancer. Therefore, the promoting effects of chemicals in two-stage bladder carcinogenesis were judged by measuring their ability to induce PN hyperplasia in rats. Male rats were given N-butyl-N-(4-hydroxybut...
متن کاملInhibition of urinary bladder tumors induced by N-butyl-N-(4-hydroxybutyl)-nitrosamine in rats by green tea.
BACKGROUND Recently, the anticarcinogenic effects of green tea have been studied in sites other than the urinary tract. The present study examined the inhibition by green tea of vesical tumors induced in rats by N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN). METHODS In the first series of experiments, 0.05% BBN was added to the drinking water of rats and remained present for 5 weeks. In one ex...
