Project description:Noxo1, a component of NADPH oxidase 1 (NOX1) complex, is upregulated in gastric cancer cells in a inflammation-dependent manner, and plays an important role in tumorigenesis (Oncogene, 33: 3820, 2014). To examine the mechanism of NOX1/ROS signaling in tumorigenesis, MKN45 gastric cancer cells were treated with apocynin, an inhibitor for NOX, and their gene expression was examined by RNA sequencing. Based on expression data, Sox2 was shown to be suppressed by apocynin, suggesting a role of Sox2 in a inflammation-associated gastric tumorigenesis.
Project description:We found that ERY974 shows only moderate antitumor efficacy in MKN45 non-inflamed tumor in huNOG mice. We also observed that ERY974 + capecitabine increases antitumour efficacy in non-inflamed MKN45 tumours. To identify a mechanism of combination effect, we compared RNA expression of MKN45 tumors treated with ERY974, capecitabine, or combination.
Project description:Gene expression profiles of in vitro selected highly metastatic MKN45-GFP sublines. The results were compared with MKN45-GFP control cell line to determine the metastasis associated genes.
Project description:Gene expression profiles of in vitro selected highly metastatic MKN45-GFP sublines. The results were compared with MKN45-GFP control cell line to determine the metastasis associated genes. Four pairs compared experiment. Each pair was used MKN45-GFP cells as correlated control. Determining on the gene expression trends were by various metastatic ability of each subline.
Project description:An RNA transcriptome sequencing analysis was performed in MKN45 cells that were transfected with tcons_00001221 shRNA or control shRNA.
Project description:Analysis to find splicing variants that are differentially expressed in a highly metastatic stomach cancer cell line, MKN45P, versus its parental cell line, MKN45 Comparison between highly metastatic gastric cancer cell line MKN45P and its parental cell line MKN45

Project description:This study set out to identify global changes in gene expression in MKN45 gastric epithelial cells following 8 hours stimulation with 10 μg/ml lipopolysaccharide (LPS) from the gastric pathogen H. pylori. Microarray analysis was used to compare changes in gene expression between cells treated with 10 μg/ml H. pylori LPS and untreated cells at the same time point.

Microarray analysis was used to compare changes in gene expression between cells treated with 10 μg/ml H. pylori LPS and untreated cells at the same time point. Total RNA was harvested from MKN45 cells following treatment with LPS for 8h or untreated cells at the same time-point. 2 independent experiments were carried out. RNA was labeled and hybridized to GeneChips to analyse changes in gene expression.
