Project description:Transcriptional profiling of MKN45 cells comparing control stably expressing Non-Targeting shRNA cells with stably expressing SET/I2PP2A targeting shRNA cells. Goal was to determine the effects of SET knockdown on MKN45 gene expression.
Project description:In order to explore the effect of miRNA on TRAIL sensitivity of gastric cancer, we selected TRAIL-sensitive MKN45 and TRAIL-resistant BGC823 gastric cancer cell line. The expression of miRNA in MKN45 and BGC823 was detected by miRNA chip. "3" is the miRNA expression file of BGC823. "4" is the miRNA expression file of MKN45.
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:Copy number profiling of MKN45T 5-FU resistant gastric cancer cell lines and its parental cell line MKN45. We hypothesized that a detailed fine-scale survey of genomic CNAs might reveal the mechanism for acquired resistant to 5-FU in gastric cancer.
Project description:Expression of SET7/9, a histone methyltransferase, was frequently reduced in cultured and primary gastric cancers. To identify the SET7/9 target genes in gastric cancer, we performed siRNA-based knockdown of SET7/9 in MKN74 and MKN45 cells and then examined significant expression changes of genes by microarray. Transfection of SET7/9 siRNA into MKN74 and MKN45 cells were performed by electroporation. After 48hrs, cells were harvested. Total RNA was used for cDNA microarray.

Project description:In order to define YAP1-specific gene expression patterns in gastric cancer, the constitutively active mutant YAP1 (YAP1-S127A) was over-expressed in MKN45 gastric cancer cells. Defined gene expression signature was later used to stratify gastric cancer patients according to the presence of the YAP1-activated signature. Three groups of samples are included: 1. Mock control; 2. Vector control; 3. YAP-S127A expression. Gene expression profiles of YAP-S127A mutant-expressing cells were compared to that of mock and vector control. Experiments were done in MKN45 gastric cancer cells.
