Expression profiling of lncRNAs/mRNA for 16 human samples derived from patients with altrophic gastritis(Hp+) or gastric cancer(Hp+)

ABSTRACT: H.pylori was a well known risk factor for gastic cancer. In this study, we used high-throughtput lncRNA microarray to screen dysregulated lncRNA in gastric cancer, and to investigate the biological function fully understood lncRNA.

lncRNAs expression signatures of gastric cancer

Project description:Long noncoding RNAs (LncRNAs) are an important class if pervasive genes involved in a variety of biological functions. LncRNAs have been recently implicated as having oncogenic and tumor suppressor roles. To further investigate the function of lncRNA in gastric cancer, we use lncRNA microarray to describe LncRNAs profiles in 6 pairs of human gastric adenocarcinoma and the corresponding adjacent nontumorous tissues. The experimental samples are divided into two groups(normal and tumor) to compare lncRNA expression profiling of those

lnc-PLCB1 is stabilized by METTL14 induced m6A modification and inhibits Helicobacter pylori mediated gastric cancer by degrading DDX21

Project description:To determine the role of m6A modification in H.pylori-mediated gastric cancer, we performed RNA methylation immunoprecipitation sequencing (MeRIP-seq) after infecting gastric cancer cell line AGS with H. pylori standard strain Hp26695 at MOI=100 for 12h. The sequencing results include three parts: mRNA, lncRNA, and circRNA.

Identification of gastric cancer associated serum antibodies using Helicobacter pylori antigen microarrays

Project description:Unbiased de-novo identification of biomarkers for H.pylori associated gastric cancer; Microarrays, representing 242 seroreactive H.pylori proteins, were generated by spotting of the respective gene constructs and cell-free on-chip expression. Antibody levels to these proteins were measured by application of sera from non-cardia gastric cancer patients and their matched controls. Possible new biomarkers, associated with gastric cancer, were evaluated by unadjusted conditional regression.

The control of H. pylori-mediated gastric cancer development and progression through YAP/TAZ signal regulation

Project description:Helicobacter pylori(H. pylori), a gastrointestinal pathogen, is known to increase the risk of gastric cancer by activating chronic pro-inflammatory signaling pathways in epithelial cells. Cytotoxin-related protein A (CagA) is known to play an important role in gastric cancer development. CagA has been reported to induce tumors by inducing overexpression of YAP/TAZ, a component of Hippo signaling, and dysregulation of the pathway, thereby promoting cell proliferation and resistance to apoptosis. However, the role of H.pylori-mediated YAP/TAZ has not yet been fully investigated. Our study aimed to investigate the role of YAP/TAZ in H.pylori-mediated Hippo pathway dysregulation in gastric carcinogenesis using H.pylori-infected gastric cancer cell lines, knockout mice, and patient-derived organoids. CagA-mediated YAP overexpression in gastric epithelial cells induced intestinal epithelial metaplasia and induced intracellular rearrangement of the binding protein ZO1, thereby conferring cell motility.

Expression data from Helicobacter positive and negative human gastritis samples

Project description:The whole-genome oligonucleotide microarray analysis gives an opportunity for studying the unidentified gene expression background of the idiopathic and H.pylori related gastric erosive alterations. Using microarrays we compared the whole genome gene expression profile of HP+ and HP- gastric erosions and normal adjacent mucosa to explain the possible role and response to HP infection and to get morphology related mRNA expression patterns. Keywords: whole genomic expression

Transcriptome expression changes in human gastric epithelial cells co-cultured with Helicobacter pylori lysate of different generations.

Project description:With the colonization of Helicobacter Pylori (H.pylori) in the human stomach, a large amount of Helicobacter Pylori (H.pylori)colonized into the stomach disintegrates and releases a large number plenty of toxic proteins and other bacterial structure components. TollToll-like receptors (TLRs) in gastric epithelial cells which sensitive to the components of bacteria lysate around the microenvironment attach them and activite innate immune and pro-inflammatory response once contact with antigen. The consequences after long-term stimulation of H.pylori lysate in gastric epithelial cells has not been reported . To investigate the effects of H.pylori lysate on TLRs expression and inflammatory cytokines level during long-term stimulation of gastric epithelial cells and clarify the potential mechanismHence, we detected TLRs mRNA level and inflammatory cytokines expression in GES-1 cells co-culture with lysate from 1 to 30 generations. The sensitivity to H.pylori or H.pylori lysate in GES-1 cells were also monitored. We also explored whether LPS was the main factors contributing to this change. Mongolian gerbils were used to replicate H.pylori infection animal model. After transcriptome sequencing，A TLR2/6 heterodimers agonist Pam2CSK4 and a highly selective inhibitor of PI3K LY294002 were used to clarify the TLR6 signaling pathways. In a conclusion, we discovered that the sensitivity of TLRs in human gastric epithelial cells decreased while after long-time co-culture with H.pylori lysate. Human gastric epithelial cells shows tolerance to H.pylori lysate in TLRs and inflammatory cytokines level. decreased the high level of TLRs and inflammatory cytokines after stimulating GES-1 cells with H.pylori lysate for a short-term. And Tthis process may works through the TLR6/PI3K/NF-κKB axis.
