Gene expression profiles of spontaneous gastric tumors in the antrum of the stomach of 30,60, and 90 day old CEA424-SV40 -T antigen transgenic mice.. Mus musculus

Analysis of global gene expression in the antral portion of the stomach in control and mice with a developing tumor to get further insight into the exact tumor type and the influence of local gene expression. Overall design: Total RNA obtained from tissue samples from the antrum. Follow up of gene expression over the time of the tumor development
