Project description:We report the application of chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-seq) for high-throughput profiling of H3K27me3 modifications in sk-hep-1(sk), sk-hep-1-shEZH2 (sks) and LO2 cells. Following standard ChIP procedure, 10 ng of each DNA sample was used for Illumina sequencing. Statistically significant ChIP-enriched regions (peaks) were identified by sk vs sks (p-value threshold of 10-2) or sk vs LO2 (p-value threshold of 10-3). Enriched peaks were annotated by the nearest gene using the newest UCSC RefSeq database. We identify genes modified by EZH2-mediated H3K27me3. This study provides insights into these down stream genes modified by EZH2 regulated H3K27me3 in HCC cell lines.

Project description:We have previously shown that Heparin (Hep) significantly inhibited Enterovirus 71 (EV71) infection and binding in both Vero and a human neural cell line, SK-N-SH, in vitro. Therefore, in this study we intended to gain insight into the cellular and molecular mechanisms of action of Hep against clinical EV71 infection in SK-N-SH cells. Instead of stating a long list of gene functions and pathways, we tried to select for EV71-induced genes that were exclusively affected by antiviral activity of Hep through a multi-level comparison and characterization. Overall, our microarray analysis may suggest that Hep might exert its anti-EV71 activity in SK-N-SH cells, at least in part, through the following mechanisms: i. Reduction of the down-regulation effect of EV71 on TOX that would lead to an increased population of effective, mature T-cells and NK-cells; ii. Reduction of the up-regulation effect of EV71 on GIP, that in turn, would reduce recruiting different GPCRs, leading to a reduced viral infection in host cells; iii. Partially neutralization of the EV71-mediated apoptosis through expression of CARP2 that acts as an anti-apoptosis ubiquitin protein ligase (E3). EV71 is a neurovirological virus that can sometimes cause severe and fatal CNS complications in infected patients. Since still there is no approved drug for prophylaxis of EV71-casued disease, discovering a molecular drug target(s) for EV71 infection would be crucial. This was the first study to report direct assessment of mechanisms of action of antivirals against EV71 infection. SK-N-SH cells were infected with a clinical EV71 isolate followed by treatment with 125 µg/mL of Hep. At 72 hours post infection, antiviral activity and cytotoxicity of Hep at 125 µg/mL in 12-well plates were carried out at the same time as RNA extraction. This way, we could ensure that we would assess transcript profiles of the host cells under the same condition and time as assessment of antiviral activity and cytotoxicity for the same replicates. Changes in expression profiles of the host cells were comparatively assessed under four conditions: cell control (neither infection nor treatment, designated CC), treated only with Hep (compound control, designated Cyto), EV71-infected cells treated with Hep (treatment, designated H), and infected with EV71 without treatment with Hep (virus control, designated V). All experiments were applied in triplicate, and totally twelve GeneChip® Human Gene 1.0 ST arrays were purchased from Affymetrix and processed. Then, the following five contrasts were made: Hep vs. CC; VC vs. CC; Cyto vs CC; Hep vs. VC; and Hep vs. Cyto. For each contrast, only samples from the two target groups were included. The statistical parameters of ANOVAs, p values, multiple test corrections, and fold changes were calculated within each contrast. Then, a multi-level selection and analysis procedure was employed in order to attribute changes in the gene transcription level to antiviral activity of Hep.

Project description:The incidence of TP53 loss-of-function in hepatocellular carcinoma is very high. In order to clarify the gene expression differences induced by the changes of TP53 gene, we used two human hepatocellular carcinoma cell lines, SK-HEP-1 and Hep 3B with TP53 knockdown or overexpression for RNA sequencing . SK-HEP-1 is a TP53 wild-type hepatocellular carcinoma cell line. Thus, we knockdown TP53 in SK-HEP-1. Hep 3B is a TP53 loss-of-function hepatocellular carcinoma cell line. Thus, we overexpress TP53 in Hep 3B. Results of RNA-seq analysis showed the differences after knocking-down or overexpressing TP53.
