Group 1a (maximally induced at 1 or 2 weeks after initiation of MNNG treatment. strain differences were constant.)

Group 2 (constantly expressed regardless of MNNG treatment.)

Other related genes

For each gene, expression profile among rat strains in the pylorus (left panels) and temporal profiles (right panels) were measured. In the middle panels, effect of MNNG exposure for 2 weeks are measured. Expression level of a gene was quantified by normalizing the copy number of the gene to that of beta-actin. The copy numbers were quantified by real-time RT-PCR. In the left panels: fACI, female ACI rats; F1, F1 rats of ACI and BUF. In the left panels: AP, ACI pylorus; BP, BUF pylorus; AF, ACI fundus; AL, ACI liver (There are the data for only MNNG(-) in liver.) In the right panels: 0W, before treatment.
