Project description:Human SNU cell lines derived from hepatocellular carcinomas associated with chronic hepatitis B virus (HBV) infection were examined. The analysis of intracellular RNA and DNA markers of HBV replication and examination of HBV RNA reads coverage of selected regions on HBV-related RNAs and polyadenylation positions within HBV sequence using RNA-sequencing suggested absence of HBV replication in SNU-423, SNU-368 SNU-398, SNU-182, SNU-449, SNU-475, SNU-354, SNU-739 and SNU-387 cells, while SNU-761 and SNU-886 still could maintain residual HBV replication. The undetectable intracellular HBV core antigen (HBcAg) and absence of significant levels of secreted core-associated and virion-associated HBV DNA confirmed the absence or profound suppression of HBV replication in parental SNU cell lines. Various 5'-human-HBV-3' and 5'-HBV-human-3' RNAs transcribed from integrated HBV DNA were found in most of SNU cell lines. The 5'-HBV-human-3' junctions suggested that several SNU cell lines could generate 5'-HBV-human-3' RNAs encoding HBV envelope proteins. The known and novel spliced HBV RNAs were detected in SNU-886, SNU-739, SNU-387, SNU-761, and SNU-354 cells. At least some of them were generated independently of HBV replication. All SNU cell lines could not support efficient HBV replication after transfection with the vector initiating efficient HBV replication in Huh7 cells. This was reflected by three distinct accumulation patterns of HBV replication markers, undetectable intracellular HBcAg, and by the lack of considerable levels of secreted core-bound and virion-associated HBV DNA. Overall, SNU cell lines represent valuable model systems for detailed analysis of integrant-transcribed HBV RNAs, spliced HBV RNAs, and mechanisms of suppression of HBV genome replication.

Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes

Project description:Analysis of Huh-7 hepatocarcinoma cell line depleted of NDRG3 or HIF-1α under hypoxic condition. HIF-1α and NDRG3 have distinct functions in hypoxia responses. Results provide insight into molecular basis of HIF-independent signaling in the development and progression of hypoxic tumors Gene expression profiles of Huh-7 cells stably expressing NDRG3-shRNA or HIF-1α-shRNA under normoxia were compared to gene expression profiles of Huh-7 stable cells under hypoxia for 6, 12 and 24 hours.
