Project description:To further analyze the gene expression profile regulated by entecavir, we employed whole genome microarray expression profiling as a discovery platform to identify the differentially expressed genes. Human hepatocellular carcinoma cell lines HepG2.2.15 cells were treated for 48 hr with 10 μmol/L entecavir or 0μmol/L entecavir(control samples) in vitro. The differentially expressed genes including all detected and normalized signal more than 8 were selected and 30 upregulated- and downregulated- genes were identified between 10μmol/L dose and control samples.Afterwards, the differentially-expressed genes were analyzed using KEGG database (http://www.genome.jp/kegg/) and none of 30 genes were related to HBV infection-related molecular interaction network were identified.
Project description:To further analyze the gene expression profile regulated by TCM Suduxing, we employed whole genome microarray expression profiling as a discovery platform to identify the differentially expressed genes. Human hepatocellular carcinoma cell lines HepG2.2.15 cells were treated for 48 hr with 0.001 μg/ml and 0.01μg/ml Suduxing or without Suduxing(control samples) in vitro. The differentially expressed genes including all detected and normalized signal more than 8 were selected and 538 upregulated- and downregulated- genes were identified between 0.01μg/ml dose and control samples.Afterwards, the differentially-expressed genes were analyzed using KEGG database (http://www.genome.jp/kegg/) and 10 genes related to HBV infection-related molecular interaction network were identified.
Project description:Analysis by LC-MS/MS shotgun proteomics was performed on lysates from the following samples: 1) Control HK2 cells generated using control CRISPR/CAS9 system and scrambled guide RNA (sgRNAGCACTCACATCGCTACATCA) 2) HK2 cells with FTO knockout using CRISPR/Cas9 system and target 2 guide RNA (sgCCTACAAGTACCTGAACACC) 3) HK2 cells with FTO knockout using CRISPR/Cas9 system and target 3 guide RNA (sgCCAGGCTCTTTACGGTCCCC) 4) HK2 cells treated with vehicle control 5) HK2 cells treated with erastin 6) HK2 cells treated with FTO inhibitor FB23-2
Project description:Purpose: We idenficied a circRNA, circBNC2, that was downregulated during tubular epithelial cell (TEC) injury. To study the function of circBNC2, we performed CRISPR-Cas9 to knock out circBNC2 in HK2 (a well recognized TEC) cells. Next-generation Sequencing was used to identified the differentially expressed mRNA between circBNC2-KO HK2 cells and wild-type HK2 cells.
Project description:To identify differentially expressed long noncoding RNAs (lncRNAs) upon TGF-β stimulation in human cultured tubular epithelial cells HK2 and HKC8, we have employed long noncoding RNA microarray expression profiling as a discovery platform to find differentially expressed lncRNAs with TGF-β stimulation in these cells. Cultured human tubular epithelial cells HK2 and HKC8 were stimulated with PBS or TGF-β1. After incubation with TGF-β1 (10ng/ml) for 24 hours, 86 overlapping lncRNAs were upregulated and 47 overlapping lncRNAs were downregulated more than 2 fold vesus cells treated with PBS in these two epithelial cell lines. Expression of ENST00000429588 from this result was quantified in the same RNA samples by real-time PCR, confirming the upregulation upon TGF-β stimulation is repeatable.
Project description:In total, 17,118 and 16,786 transcripts were detected in olaparib- and DMSO-treated cells, respectively. Analysis of differentially expressed genes (DEGs) revealed 866 genes, including 503 upregulated and 363 downregulated genes in olaparib-treated cells). Volcano plots indicated the upregulation of inflammatory cytokine-related genes . Enrichment analyses using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database20,21 identified inflammation-related pathways as prominently upregulated in olaparib-treated cells, with five of the top 10 pathways involving inflammation-related genes. Dot plot analyses also confirmed the upregulation of inflammatory hallmarks, such as TNFA signaling via NFκB, inflammatory response, IL2-STAT5 signaling and interferon gamma response, in olaparib-treated cells. Furthermore, the GSEA determined significant enrichment of inflammatory cytokine-related KEGG pathways, including cytokine–cytokine receptor interaction, JAK-STAT signaling, and Rig I like receptor signaling pathways, as well as inflammatory hallmarks such as TNFA signaling via NFκB, interferon alfa response, and interferon gamma response in olaparib-treated cells.
Project description:HK-2 cells were treated with MGO, carnosine, or combination of both. Differentially expressed proteins (DEPs) were identified by iTRAQ-based mass spectrum, annotated with Gene Ontology (GO) followed by enrichment analysis of GO items and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways.
