Project description:The Wnt signaling pathway is involved in many differentiation events during embryonic development and can lead to tumor formation after aberrant activation of its components. ?-catenin, a cytoplasmic component, plays a major role in the transduction of the canonical wnt/ ?-catenin signaling. The aim of this study was to identify novel genes that are regulated by active ?-catenin/TCF signaling in hepatocellular carcinoma. We selected and expanded isogenic clones from hepatocellular carcinoma-derived Huh7 cells with high and low ?-catenin/TCF activities. We showed that, high TCF activity Huh7 cells lead to bigger and more aggressive tumors when xenografted into nude mice. We used SAGE (Serial Analysis of Gene Expression), genome-wide microarray and in silico promoter analysis in parallel, to compare gene expression between low (basal) and high (transfected) ?-catenin/TCF activity clones, those had been xenografted into nude mice. We compared and contrasted SAGE and genome-wide microarray data, in parallel. Finally; after combined analysis, we identified BRI3 and HSF2 as novel targets of Wnt/?-catenin signaling in hepatocellular carcinoma. High TCF activity Huh7 cell line (Huh7-S33Y) was compared to control Huh7 cell line (Huh7-Vec) by using 25 ug of total RNA isolated from each sample

Project description:The Wnt signaling pathway is involved in many differentiation events during embryonic development and can lead to tumor formation after aberrant activation of its components. Β-catenin, a cytoplasmic component, plays a major role in the transduction of the canonical wnt/ β-catenin signaling. The aim of this study was to identify novel genes that are regulated by active β-catenin/TCF signaling in hepatocellular carcinoma. We selected and expanded isogenic clones from hepatocellular carcinoma-derived Huh7 cells with high and low β-catenin/TCF activities. We showed that, high TCF activity Huh7 cells lead to bigger and more aggressive tumors when xenografted into nude mice. We used SAGE (Serial Analysis of Gene Expression), genome-wide microarray and in silico promoter analysis in parallel, to compare gene expression between low (basal) and high (transfected) β-catenin/TCF activity clones, those had been xenografted into nude mice. We compared and contrasted SAGE and genome-wide microarray data, in parallel. Finally; after combined analysis, we identified BRI3 and HSF2 as novel targets of Wnt/β-catenin signaling in hepatocellular carcinoma. Experiment Overall Design: High TCF activity Huh7 cell line (Huh7-S33Y) was compared to control Huh7 cell line (Huh7-Vec) by using 10 ug of total RNA isolated from each sample (15 ug of labeled cRNA was hybridized to the arrays). Triplicates are coming from same total RNA extraction.

Project description:Analysis of Huh7 hepatocellular carcinoma (HCC) cells depleted for potassium channel KCa3.1, the intermediate conductance calcium-activated potassium channel. Result provide insight into the role of KCa3.1 in the carcinogenesis of HCC. We used microarrays to detail the gene expression differences between KCa3.1 knockdown and negative control in Huh7 HCC cells.

Project description:In development, pioneer transcription factors access silent chromatin to reveal lineage-specific gene programs. The structured DNA-binding domains of pioneer factors have been well characterized, but whether and how low-complexity intrinsically disordered regions (IDRs) affect chromatin and control cell fate is unclear. Here, we report deletion of an IDR of the pioneer factor TCF-1, termed “L1”, leads to an early developmental block in T cells. The few T cells that develop from progenitors expressing TCF-1 lacking L1 exhibit lineage infidelity distinct from the lineage diversion of TCF-1 deficient cells. Mechanistically, L1 is required for activation of T cell genes and de-repression of GATA2 driven genes, normally reserved to the mast cell and dendritic cell lineages. Underlying this lineage diversion, L1 mediates binding of TCF-1 to its earliest target genes which are subject to repression as T cells develop. These data suggest TCF-1’s intrinsically disordered N-terminus maintains T cell lineage fidelity.

Project description:A powerful approach to study innate antiviral response is to compare the difference between wild type Huh7 cells, which do not support robust replication of hepatitis C virus (HCV)2, versus certain subclones of Huh7 cells that are permissive for HCV replication. We generated two permissive cell lines and two independent non-permissive subclone from Huh7 cells. We compared the global methylation pattern of these different cells and find that Huh7 cells exist as a heterogeneous population of cells with distinct patterns of gene methylation. Comparison of Huh7, HRP1, HRP4, Huh7-pNeo1 and Huh7-pNeo2 cells.
