MRNA profiling in gastric cancer cell line AGS upon miR-25-3p silencing

ABSTRACT: Genome-wide mRNA expression profiling was performed in AGS, gastric cancer cell line, upon miR-25 silencing. At 48 hours upon anti-miR-25-3p (miRNA inhibitor) and non-targeting control RNA transfection, the whole transcriptome profiling was performed in triplicates. The miR-25 silencing elevates the diffuse gastric cancer features like expression of COL1A2, expression of COL1A2 co-expressed genes, Epithelial to Mesenchymal Transition (EMT) and angiogenesis associated genes.

mRNA profiling of AGS Gastric Cancer cell line treated with the Homeopathy formulation, Ornithogalum

Project description:Ornithogalum is one of the therapeutic formulation used in homeopathic treatments. It is specifically used in the treatment for gastric and duodenal ulcerations. Towards understanding the anticancer mechanism, we investigated the genome-wide mRNA changes upon treating AGS Gastric Cancer cells with Ornithogalum. We observed that totally 707 genes were significantly regulated upon Ornithogalum Treatment, among them 246 genes were upregulated and 461 genes were downregulated. The results provide insight into molecular implication and gene level expression of AGS upon treatment with Ornithogalum. Total RNA was isolated from AGS gastric cancer cells treated with 0.01% of ornithogalum and ethanol control and profiled using Affymetrix Human Gene 1.0 ST Array (HuGene-1_0-st).

Gene expression profiling of shCtrl and shGABRD AGS cells from Clariom S array

Project description:GABRD is identified as a tumor promotor in the development of gastric cancer. Herein, to further explore the downstream regulated genes involved in GABRD mediated tumor progression, an Affymetrix Clariom S human Assay was performed to profile the expression of GABRD regulated genes in AGS cells. Gene expression profiling of shCtrl and shGABRD AGS cells was acquired and analyzed. Differentially expressed genes were identified based on fold change of mean of expression (fold change ≥ 1.5) and FDR (< 0.05) from P value calculated based on linear model of empirical Bayesian distribution. GABRD expression regulated the expression of 2644 genes in AGS cells, of which 1199 were upregulated and 1445 were downregulated upon GABRD silencing.

Gene expression profiling of AGS Gastric Cancer cells upon YY1 knock down

Project description:Yin Yang 1 (YY1) is a ubiquitous transcription factor belonging to the GLI-Kruppel class of zinc finger proteins regulating diverse biological processes including cell proliferation, development, DNA damage responses and also involved in carcinogenesis. The protein is involved in repressing and activating a diverse number of promoters.In order to study the role of the transcription factor YY1 in gastric cancer, transcriptome wide gene expression analysis was performed upon silencing the YY1 gene in gastric cancer cell line, AGS using Affymetrix Human Transcriptome 2.0 array. Transcriptome Analysis Console (TAC) Software was used for the analysis of differentially expressed genes between AGS_YY1_siRNA transfected and AGS_NTC_siRNA transfected cells.

RNA-seq in AGS-EBV, shRNA

Project description:Gastric cancer is one of the most common cancers worldwide. Epstein-barr virus-associated gastric cancer accounts for about 10% of all gastric cancers. EBV itself expresses a variety of proteins and regulates the expression of host genes. In this study, we examined the knockdown of BC200 and eIF4A3 in AGS-EBV, respectively, and analyzed its effect on host mRNA expression.

Expression data of EBV-positive and EBV-negative subclones of gastric adenocarcinoma cell line AGS

Project description:Gastric cancer is one of the most common cancers worldwide. Epstein-Barr virus-associated gastric cancer accounts for approximately 10% of all gastric cancers. EBV expresses its own proteins and miRNAs (BART miRNAs) and regulates host gene expression. In this study, we examined the effect of EBV infection on host mRNA expression. Differential gene expression was analyzed between EBV-negative human gastric cancer cell line AGS and EBV-positive human gastric cancer cell line AGS-EBV.

Epigenetic silencing of miR-210 increases the proliferation of gastric epithelium during chronic Helicobacter pylori infection

Project description:Persistent colonization of the gastric mucosa by Helicobacter pylori (Hp) elicits chronic inflammation and aberrant epithelial cell proliferation, which increases the risk of gastric cancer. We examined the ability of microRNAs to modulate gastric cell proliferation in response to persistent Hp infection and found that epigenetic silencing of miR-210 plays a key role in gastric disease progression. Importantly, DNA methylation of the miR-210 gene was increased in Hp-positive human gastric biopsies as compared to Hp-negative controls. Moreover silencing of miR-210 in gastric epithelial cells promoted proliferation. We identified STMN1 and DIMT1 as miR-210 target genes and demonstrated that inhibition of miR-210 expression augmented cell proliferation by activating STMN1 and DIMT1. Together, our results highlight inflammation-induced epigenetic silencing of miR-210 as a mechanism of induction of chronic gastric diseases, including cancer, during Hp infection. To identify miR-210 targets in gastric cells, whole transcriptome analysis of AGS and MKN45 cells transfected with pre-miR-210 was conducted using Affymetrix GeneChip Human Genome U133 Plus 2.0 Array.
