Project description:sequential changes in gene expression profiles in the gastric adenoma-carcinoma sequence by analyzing eight patient-matched gastric normal mucosa, adenomas and carcinomas. We examined gene expression changes during the gastric adenoma-carcinoma sequence in 26 snap-frozen samples (normal mucosa, adenoma, and carcinoma samples from eight patients and two additional carcinomas) by oligonucleotide microarray

Project description:In this study, we aimed to reveal whether gastric mucosa with AIG has a specific gene expression profile, involving in its histology and chronic inflammation. To approach this, we performed comprehensive analysis of gene expression using gastric mucosa with atuoimmune gastritis, that with H. pylori-associated gastritis and healthy mucosa without any inflammation. Potential mechanisms of the gene expression changes in gastric mucosa with AIG were also explored.
Project description:Gastric Carcinoma is a very serious condition. Tumors are often not detected until late, and 5-year survival rates are 20%. Early diagnosis or prediction of gastric cancer is of outmost importance. Molecularly, those tumours are not well characterized. <br><br> Aim: by use of cDNA microarray to do a three-way comparison of gene expression patterns between tumour (T), flat (non-cancerous) mucosa (N) from stomachs with carcinoma, and normal mucosa in matched controls (K). Our first goal was to look at genes commonly differentially expressed between TvsN and TvsK (both criteria fulfilled) and NvsK. <br><br> Subjects and methods: We analyzed gene expression in tumor and flat mucosa biopsies from seven patients with gastric carcinoma and in age/sex matched samples from healthy individuals. Total RNA was extracted and samples (2 ug total RNA) were labeled for cDNA microarray analysis using Genisphere's 3DNA dendrimer kit. The gene expression patterns for 12759 genes were analyzed.
Project description:Comparative analysis of gene expression in murine gastric fundic mucosa in wild-type and Lasp1-null littermates. The data provide a comprehensive overview of genes expressed in the mouse gastric mucosa and show that the expression of several known and unidentified genes is modified by disruption of the Lasp1 gene. Keywords: Genotypic comparison
Project description:Comparative analysis of gene expression in murine gastric fundic mucosa in wild-type and Lasp1-null littermates. The data provide a comprehensive overview of genes expressed in the mouse gastric mucosa and show that the expression of several known and unidentified genes is modified by disruption of the Lasp1 gene. Keywords: Genotypic comparison Total mRNA isolated from fundic gastric mucosae of three-month old mice, C57Bl/6Ncr strain, was used for this comparison.
