Rat stomach cancers induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) are widely used as a model of differentiated-type human stomach cancers. ACI/NJcl (ACI) rats show persistent and strong cell proliferation in response to gastric mucosal damage by MNNG while BUF/NacJcl (BUF) rats show transient and limited cell proliferation. This difference is considered as one of the mechanisms for the high susceptibility of ACI rats to MNNG-induced stomach carcinogenesis. To identify genes involved in the differential induction of cell proliferation, cDNA subtraction was performed using RNA isolated from the pylorus of ACI and BUF rats treated with MNNG. By the temporal patterns of their expressions, the isolated 16 genes were overviewed and clustered into groups. Expression of the genes in group 1 (such as MHC class I and class II genes and interferon-inducible genes Iigp, Mx2 and Ubd) was induced by MNNG treatment, and the genes in group 2 (such as cellular retinoic acid-binding protein II (CrabpII)) were constantly expressed regardless of MNNG treatment. Then, expression profiles among multiple rat strains were compared with the extents of induction of cell proliferation. Iigp, CrabpII and EST222005 were found to show relatively good accordance, and these three genes were considered as candidates for genes that control differential induction of cell proliferation. Presence of polymorphisms at the genomic DNA level was indicated for CrabpII and EST222005, and these two genes were considered to be better candidates than IIGP: It was shown that the temporal profiles and profiles among strains, taking advantage of animal models, are useful to select candidate genes from a collection of genes isolated by various genome-wide scanning methods.
