Project description:To determine the effects of UBL5 on genome-wide gene expression, we used UBL5 siRNA to knock down UBL5 in HepG2 and Huh7 cells. We then performed gene expression profiling analysis using data obtained from RNA-seq.
Project description:Purpose: To build a differential transcriptome network in Smug1 knock-out HepG2 hepatocarcinoma cells. Methods: Transcriptome analysis by the RNA-seq via mRNA pull-down. Results: We constructed transcriptome from Smug1 knock-out cells by using RNA-seq analysis. Nucleosome and miRNA related genes were highly enriched in Smug1 KO HepG2 cells. Conclusions: Smug1 regulate the gene expression related with nucleosome assembly and histone function.
Project description:HNF4a is an important liver transcription factor that regulates at least a thousand genes in the liver. Here we used expression profiling in HepG2 cells, a hepatocellular carcinoma cell line, in which HNF4a was knocked down by RNAi to identify some of those target genes. This dataset accompanies the article in Hepatology 2010 Feb;51(2):642-53. Integrated approach for the identification of human hepatocyte nuclear factor 4alpha target genes using protein binding microarrays by Bolotin E, Liao H, Ta TC, Yang C, Hwang-Verslues W, Evans JR, Jiang T, Sladek FM. RNA interference (RNAi) against HNF4a2 was performed in HepG2 cells using small, interfering RNAs (siRNAs) corresponding to nucleotides +179 to +197 of human HNF4A (NM_178849, sense siRNA: 5'-UGUGCAGGUGUUGACGAUGdTdT-3', antisense siRNA 5'-CAUCGUCAACACCUGCACAdTdT-3') (Dharmacon, Lafayette, CO). Total RNA was extracted with Trizol (Life Technologies, Carlsbad, CA) and reverse transcribed with the Reverse Transcription System (Promega, Madison, WI). Polymerase chain reaction (PCR) amplification was performed in the linear range (see Supporting Table 3B for a list of PCR primers). Expression profiling analysis was performed with Affymetrix oligonucleotide arrays (HGU133 Plus 2.0) using RNA from control (PGL3 siRNA) or treated (HNF4a siRNA) HepG2 cells
Project description:scRNAseq data of scrambled and siRNA-mediated knock-down (96h) of the minor spliceosome snRNA U6atac in androgen-sensitive LNCaP cells and in patient derived neuroendocrine organoids (PM154). Three replicates for each cell line.
Project description:We developed genetically engineered HepG2/8F_HS cells, in which eight liver-enriched transcription factor (LETF) genes—hepatocyte nuclear factor (HNF)-1α, HNF-1β, HNF-3β, HNF-4α, HNF-6, CCAAT/enhancer binding protein (C/EBP)-α, C/EBP-β and C/EBP-γ— under the control of TRE/PCMVmin promoter were introduced into a previously developed human hepatoma cell line (HepG2-HSP). The heat-inducible synthetic promoter system was introduced into HepG2 cells and tetracycline-responsive transactivator (tTA) and enhanced green fluorescent protein (EGFP) were expressed via positive feedback of tTA transcription in response to heat treatment. HepG2/8F_HS cells can induce high liver functions by heat treatment via overexpression of LETF genes.
Project description:Effect of PAAF1 and Spt6 knock-down on gene expression. Total RNAs were extracted from HeLa-LTR-Luc cells in which PAAF1 or Spt6 had been knock down by a specific siRNA or HeLa-LTR-Luc cells that had been transfected with a control siRNA (“si Neg”). Differentially expressed genes in PAAF1 knock-down cells were identified by microarray.
