Transcription profiling of gastric tissues from mice infected with H. pylori strain SS1 for 6 or 12 months

ABSTRACT: 12 C57BL/6 mice were infected orogastrically with the H. pylori strain SS1. After 6 and 12 months, 3 non-infected and 3 infected mice were sacrificed and stomachs isolated. Gastric tissues were disaggregated and total RNA were isolated by TRIzol extraction and then purified on RNeasy minicolumns. After synthesis of the first cDNA strand (In vitrogen), the double-stranded cDNA was obtained and used to produce biotin-labeled cRNA (Enzo Diagnostic). FRagmented cRNA was hybridized to GeneChip Mouse expression array 430A (Affymetrix).
