ABSTRACT: We are investigating hepatic transcriptional responses associated with castration and tumorigenic hepatitis induced by Helicobacter hepaticus infection in mature male A/JCr mice; Microarray data demonstrated a global loss of gender-dimorphic gene expression regulation in mice with chronic hepatitis and liver cancer Experiment Overall Design: Male A/JCr mice were inoculated with H. hepaticus or vehicle at 4 weeks; some underwent castration at 1 year, and all were necropsied at 21 months
Project description:We are investigating the transcriptional response of mice infected with Helicobacter hepaticus and links to liver cancer; We used microarrays to detail the global programme of gene expression underlying H. hepaticus induced liver cancer Experiment Overall Design: Mice with tumors were compared to mice with infection only (comparison 2) and mice infected were compared to control mice (comparison 1)

Project description:To identify molecular singnal alterations between androgen dependent prostate cancer and castration resistant prostate cancer, we performed interspecies comparative microarray analyses using RNAs prepared from uncastrasion and castration tumor from LNCAP Orhotopic xenograft models of prostate cancer. microarray data from uncastrasion and castration tumor revealed that the gene expression profile is most significantly altered in between androgen dependent prostate cancer and castration resistant prostate cancer. Comparative analyses of LNCAP Orhotopic xenograft models of prostate cancer showed that genes involved in androgen dependent and androgen independent tumor were significantly altered. We prepared RNA samples from 4 samples uncastrasion and 4 samples castration tumors from LNCAP Orhotopic xenograft models of prostate cancer . High-quality RNA samples were subjected to microarray analysis using the Affymetrix Human Gene 2.0 ST platform, and only those results that passed examinations for quality assurance and quality control of the Human Gene 2.0 ST arrays were retrieved. In total, we obtained gene expression profiles from the following samples: 4 samples uncastrasion and 4 samples castration tumors
Project description:We evaluated aflatoxin B1-induced liver tumor promotion by H. hepaticus. Microarrays of liver and cecum from female mice were used to evaluate the individual and combined transcriptional effects of AFB1 and H. hepaticus Keywords: Tumor co-promotion study
