Phenobarbital 15-17 transforming growth factor alpha Mus musculus 76-85 14742323-0 2004 Activation of beta-catenin provides proliferative and invasive advantages in c-myc/TGF-alpha hepatocarcinogenesis promoted by phenobarbital. Phenobarbital 126-139 transforming growth factor alpha Mus musculus 83-92 14742323-2 2004 Given that PB selectively promoted initiated cells harboring beta-catenin mutations during chemically induced hepatocarcinogenesis and that Wnt/beta-catenin signaling is involved in both anti-apoptotic and proliferative processes, we now have extended our analysis to investigate whether promotion by PB affects the occurrence of beta-catenin mutations in c-myc/TGF-alpha-driven tumors. Phenobarbital 11-13 transforming growth factor alpha Mus musculus 362-371 14742323-3 2004 The frequency of beta-catenin activation as judged by somatic mutations and/or nuclear localization was significantly increased in hepatocellular carcinomas (HCCs) from c-myc/TGF-alpha mice treated with PB (15/28; 53.6%) as compared with that in control HCCs (2/28; 7.1%). Phenobarbital 203-205 transforming growth factor alpha Mus musculus 175-184 14742323-8 2004 These findings show that PB treatment positively selects for a cell population displaying activation of beta-catenin in c-myc/TGF-alpha HCCs. Phenobarbital 25-27 transforming growth factor alpha Mus musculus 126-135 11560253-2 2001 In this study, we investigated immunohistochemically the association between expression of TGF-alpha and cell proliferation activity in mouse hepatoblastomas (HBs) and hepatocellular carcinomas (HCCs) induced in B6C3F1 mice by diethylnitrosamine and sodium phenobarbital. Phenobarbital 250-270 transforming growth factor alpha Mus musculus 91-100 10942533-0 2000 Promotion of hepatocarcinogenesis by phenobarbital in c-myc/TGF-alpha transgenic mice. Phenobarbital 37-50 transforming growth factor alpha Mus musculus 60-69 10942533-9 2000 We believe that the PB-dependent modification of tumorigenesis in the livers of c-myc/TGF-alpha mice was predominantly a result of the ability of this drug to block cell death during the early stages of tumor development. Phenobarbital 20-22 transforming growth factor alpha Mus musculus 86-95 9934848-0 1999 Phenobarbital promotes liver growth in c-myc/TGF-alpha transgenic mice by inducing hypertrophy and inhibiting apoptosis. Phenobarbital 0-13 transforming growth factor alpha Mus musculus 45-54 9934848-13 1999 We conclude from our data that PB stimulates liver growth in double transgenic c-myc/TGF-alpha mice by induction of liver hypertrophy and inhibition of apoptosis, brought about by both a decrease in signaling through the TGF-beta pathway and an increase in Bcl-2. Phenobarbital 31-33 transforming growth factor alpha Mus musculus 85-94 7923571-0 1994 Rapid development of hepatic tumors in transforming growth factor alpha transgenic mice associated with increased cell proliferation in precancerous hepatocellular lesions initiated by N-nitrosodiethylamine and promoted by phenobarbital. Phenobarbital 223-236 transforming growth factor alpha Mus musculus 39-71 7923571-14 1994 In conclusion, TGF-alpha transgenic mice clearly demonstrated enhanced sensitivity to the development of hepatocellular carcinoma in the DEN initiation and PB promotion regime, possibly through a mechanism of increased hepatocyte proliferation in precancerous lesions (foci and adenomas), driven by high expression of the mitogen TGF-alpha in these lesions. Phenobarbital 156-158 transforming growth factor alpha Mus musculus 15-24 8364928-7 1993 These results demonstrate that chemical agents as diverse as nitrosamines and phenobarbital act as cocarcinogens with TGF-alpha in the livers of these transgenic mice, indicating that TGF-alpha possesses the unique ability to complement both initiation and promotion in hepatocarcinogenesis. Phenobarbital 78-91 transforming growth factor alpha Mus musculus 118-127 8364928-7 1993 These results demonstrate that chemical agents as diverse as nitrosamines and phenobarbital act as cocarcinogens with TGF-alpha in the livers of these transgenic mice, indicating that TGF-alpha possesses the unique ability to complement both initiation and promotion in hepatocarcinogenesis.
