Identification of differentially expressed mRNAs in HCSC cell lines compared with HCC cell lines
Ontology highlight
ABSTRACT: Hep3B and Huh7 are two types of human hepatoma cell lines (HCC). In our laboratory, we cultured their stem-like cancer cells (HCSCs), Hep3B-C and Huh7-C. And we have demonstrated that these cells had enhanced stem cell properties, drug resistance, properties of EMT, and stronger tumor-initiating capabilities. To explore functionally crucial mRNAs in HCSCs, 2 samples of HCSCs and 2 samples of HCCs were sequenced by the Illumina Genome Analyzer II. Through differential expression analysis, we finally identified 115 up- and 402 down-regulated miRNAs which were consistently up- and down-regulated in two stem cells compared to the cancer cells. Expression analysis using total RNAs extracted from 2 HCSC cell lines (Hep3B-C and Huh7-C), and 2 HCC cell lines (Hep3B and Huh7).

Project description:The proteomic profiling of nine commonly used HCC cell lines Hep3B, HepG2, HepG2.2.15, HUH7, PLC/PRF/5, MHCC97L,MHCC97H,HCCLM3 and HCCLM6
Project description:Global miRNA expression upon HDAC inhibition was analyzed using miRNA sequencing in HCC cell lines (HLE, HLF, Huh7, HepG2, Hep3B) and normal liver cell lines (THLE-2, THLE 3)
Project description:To evaluate small non-coding dysregulation in HCC cells, we sequenced hepatocellular carcinoma cell lines Huh7, HepG2, and Hep3B and normal liver cell HL7702 to compare their mall non-coding RNA profiles.
Project description:Hepatocellular carcinoma (HCC) represents the major subtype of liver cancer, characterized with a high rate of recurrence and heterogeneity. Liver cancer stem cells (CSCs) may account for a hierarchical organization of heterogeneous cancer cells. However, how liver CSCs sustain their self-renewal remains largely unknown. We used microarrays to discover the long non-coding RNAs (lncRNAs) expression underlying cell stem cell (CSC) and non cell stem cell (non-CSC) and identified distinct lncRNAs during this process. We sorted CD13+CD133+ and CD13-CD133- cells from Hep3B, Huh7, and PLC/PRF/5 HCC cell lines as liver CSCs and non-CSCs, then hybridized on Affymetrix microarrays. We sought to identify distinct lncRNAs in liver CSCs.
Project description:Bmi1 plays a pivotal role in hepatic carcinoma (HCC), but its targets in HCC is unknown. To screen the potential targets, we transfected HCC cell line Huh7 and Hep3B with Bmi1 shRNA lenti-virus. After confirming the Bmi1 was knocked down using western blotting, we extracted total RNA and then run the microarray detection. Gene expression profiles in Bmi1 KO cells were compared with those in Bmi1 WT cells to screen potential targets of Bmi1.
Project description:The goal of this study was to delineate the important EZH2 direct target genes that mediate the oncogenic properties of EZH2 in HCC. The EZH2 direct target genes in two HCC cell lines were identified by chromatin immunoprecipitation microarray (ChIP-chip) analysis and later confirmed by independent ChIP-PCR. The functions of the target genes were further examined. Two human HCC cell lines, Huh7 and PLC/PRF/5 (PLC5), were grown in DMEM supplemented with 10% fetal bovine serum. ChIP assays were performed using anti-EZH2 antibody. The immunoprecipitated and input DNA were used to probe the Agilent human ChIP-chip arrays.
