Research Abstract

We obtained gene expressions profiles of rat ventral prostate tissue treated with three kinds of carcinogens, -amino-l-methyl-6-phenylimidazo [4,5-b]pyridine (PhIP), 3, 2'-dimethyl-4-aminobiphenyl (DMAB)and cadmium. There were only three genes that was commonly up regulated in the 3 chemicals. Among the genes, we focused on oncomodulin and performed immunhistochemicl analysis for expression of oncomodulin in ventral prostates treated with the chemicals. Oncomodulin demonstrated sporadic positivity in cytoplasms of the prostate glands. However, there were no differences for expressions of oncomodulin between non-treated control group tissues and the 3 carcinogenic chemical groups, except for DMAB. There results indicated that the oncompdulin expression analysis may not be suitable for a in vivo screening method for prostate carcinogens.
