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.

LncRNA and mRNA expression profiles from human GES-1 cells in response to Helicobacter pylori infection

Project description:Research on lncRNAs expression profiles in human interactions with Helicobacter pylori (H.pylori) is rare reported. We used HTA2.0 to investigate the expression changes of lncRNAs and mRNAs in human gastric epithelial cells (GES-1 cell line) infected with or without H.pylori infection. Our study provided a preliminary exploration of lncRNAs expression profiles in H.pylori-infected cell models by microarray. A subset of aberrantly expressed lncRNAs was verified by qRT-PCR. These dysregulated lncRNAs might contribute to the pathological processes during H.pylori infection. We infected GES-1 cells with H.pylori as experimental groups,and cells without H.pylori infection were regarded as control groups. After 24hr-infection, cells of each group were selected for total RNA extraction and hybridization on Affymetrix HTA2.0 arrays. The aberrant expression profiles of lncRNAs and mRNAs were explored by microarray analysis between experimental and control groups.

Transcriptome profiling of m6A mRNA modification in GES-1 cells infected by Helicobacter pylori

Project description:Helicobacter pylori (H.pylori) infection is an important factor in the occurrence of human gastric diseases, but its pathogenic mechanism is not clear. N6-methyladenosine (m6A) is the most prevalent reversible methylation modification in mammalian RNA and it plays a crucial role in controlling many biological processes. We used MeRIP-seq technology to sequence the GES-1 cells infected with Helicobacter pylori(H. pylori) for 48 h.

Rat Astrocyte-Neuron Co-cultures versus purified co-cultured Astrocytes versus Astrocyte alone

Project description:Profiling of transcriptional changes in rat astrocytes when co-cultured with neurons: comparison of astrocytes cultured alone with astrocytes co-cultured with mouse hippocampal neurons. Co-cultured astrocytes are isolated using cold jet, a novel tool for these neuron-glia cultures. Over the last decade, the importance of astrocyte-neuron communication in neuronal development and synaptic plasticity has become increasingly clear. Since neuron-astrocyte interactions represent highly dynamic and reciprocal processes, we hypothesized that at least part of the involved astrocyte genes may be regulated as a consequence of their interactions with maturing neurons. In order to identify such neuron-induced astrocyte genes in vitro, we tested the effectiveness of the ‘cold jet’, a new method for separation of neurons from co-cultured astrocytes. The cold jet method is performed under ice-cold conditions and avoids protease-mediated isolation of astrocytes or time-consuming centrifugation, yielding intact astrocyte mRNA with approximately 90% of neuronal RNA removed. Using this method, we executed genome-wide profiling in which RNA derived from astrocyte-only cultures was compared with astrocyte RNA derived from differentiating neuron-astrocyte co-cultures. Data analysis revealed changes in expression of a large number of mRNAs and biological processes, including novel findings. Thus, cold jet is an efficient method to separate astrocytes from neurons in co-culture, and in this study reveals that neurons induce robust gene-expression changes in co-cultured astrocytes.
