Project description:In order to find a new genes regulated by SMARCA4, RNA was extracted 2days after transfection of si-SMARCA4 into a Hep3B cell line. We hypothesized that when SMARCA4 was inhibited, the genes expression will be suppressed.

Project description:Overexpression of SOX4 in various kinds of cancers specimen was associated with poor prognosis of patients; however, the role of SOX4 in angiogenesis or tumor microenvironment modulation remains unclear. Therefore the endogenous SOX4 was knockout and the differential gene expression between Hep3B and Hep3B SOX4-/- cells were examined via genechip. We found that the differentially expressed genes, EzH2, a SOX4-associated partner, and CXCL12, were repressed in Hep3B SOX4-/- cells compared with parental Hep3B; these results were further assessed via qRT-PCR in Hep3B SOX4-/- versus Hep3B cells.

Project description:Purpose: The purpose of this study was to develop a framework for analyzing RPE expression profiles from zebrafish eye mutants. Methods: The fish model we used was smarca4 (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4), a retinal dystrophic mutant that the retinal phenotype and expression profiles were previously characterized. Histological and Affymetrix GeneChip analyses were conducted to define the RPE defects and underlying differential expression respectively. Results: Histological analysis indicates that smarca4 RPE was formed but its differentiation was abnormal. In particular, ultra-structural analysis of smarca4 RPE by transmission electron microscopy showed a number of defects in melanogenesis, suggesting that the cytoskeletal dynamics was impaired. To compare the expression profile of normal wild-type (WT) and smarca4 RPE, their retinas and RPE-attached retinas were microdissected and the gene expression values of these tissues measured by Affymetrix GeneChip analysis. The RPE expression values were then estimated from these samples using an approach previously established by us. A factorial analysis was conducted using the expression values of RPE, retinal as well as the whole-embryo samples. Specific rules (contrasts) were built using the coefficients of the resulting fitted model to select for three groups of genes: 1) Smarca4-regulated RPE genes, 2) Smarca4-regulated retinal genes, and 3) Smarca4-regulated RPE genes that are not differentially expressed in the retina. The latter group consists of 39 genes that are highly related to cytoskeletal dynamics, melanogenesis, paracrine and intracellular signal transduction. Conclusions: Our analytical framework can potentially identify genes in zebrafish mutants that both retina and RPE are affected by the underlying mutation. The gene expression levels of three independent replicates of WT whole embryos (WA52), WT retinas (WR52), WT RPE-attached retinas (WRR52), smarca4/yng retinas (YR52), smarca4 RPE-attached retinas (YRR52) and smarca4 whole embryos (YA52) were measured by Affymetrix Zebrafish Whole Genome Arrays. All samples were collected at 52 hpf. The probe-level data of these sample groups were background adjusted, normalized and summarized by a robust multiarray average (RMA) algorithm. RPE expression values were estimated from the comparison between the retinal and RPE-attached retinal samples of the same genotype based on a method we previously developed (Leung et al., Invest Ophthalmol Vis Sci. 2007; 48:881). Then, a 3x2 factorial design was used to analyze the expression values of three kinds of tissue (T): whole embryo, retina and RPE in two kinds of mutation (M) background: WT and smarca4. Using the coefficients from the fitted models, contrasts were built to identify candidate genes that fulfilled specific criteria. The false discovery rate (FDR) q-value cutoff for a contrast was 0.001. Several contrasts were ultimately combined to allow for selection of genes that were regulated by Smarca4 in the retina and RPE. These include 1) Smarca4-regulated RPE genes, 2) Smarca4-regulated retinal genes, and 3) Smarca4-regulated RPE genes that are not differentially expressed in the retina.

Project description:The packaging of DNA into chromatin plays an important role in transcriptional regulation and nuclear processes. Brahma related gene-1 SMARCA4 (also known as BRG1), the essential ATPase subunit of the mammalian SWI/SNF chromatin remodeling complex, uses the energy from ATP hydrolysis to disrupt nucleosomes at target regions. Although the transcriptional role of SMARCA4 at gene promoters is well-studied, less is known about its role in higher-order genome organization. SMARCA4 knockdown in human mammary epithelial MCF-10A cells resulted in 176 up-regulated genes, including many related to lipid and calcium metabolism, and 1292 down-regulated genes, some of which encode extracellular matrix (ECM) components that can exert mechanical forces and affect nuclear structure. ChIP-seq analysis of SMARCA4 localization and SMARCA4-bound super-enhancers demonstrated extensive binding at intergenic regions. Furthermore, Hi-C analysis showed extensive SMARCA4-mediated alterations in higher-order genome organization at multiple resolutions. First, SMARCA4 knockdown resulted in clustering of intra- and inter- sub-telomeric regions, demonstrating a novel role for SMARCA4 in telomere organization. SMARCA4 binding was enriched at TAD (Topologically Associating Domain) boundaries, and SMARCA4 knockdown resulted in weakening of TAD boundary strength. Taken together, these findings provide a dynamic view of SMARCA4-dependent changes in higher-order chromatin organization and gene expression, identifying SMARCA4 as a novel component of chromatin organization. Hi-C and RNA-seq experiments were conducted in MCF-10A shSCRAM and shSMARCA4 cells. SMARCA4 ChIP-seq was conducted in wildtype MCF-10A cells.

Project description:A previous study from this laboratory demonstrated that up-regulating HNF4a could reverse the malignant phenotypes of HCC by inducing redifferentiation of HCC cells to hepatocytes. To study the mechanisms of the hepatic differentiation effect by HNF4α, we used the cDNA microarray to detect differential gene expression profiles of Hep3B infected with AdHNF4α and AdGFP. Expression profile analysis revealed that HNF4α positively regulated 1218 mRNAs and negatively regulated 1411 mRNAs for more than 2 times. The pathway analysis for the differential genes showed that the genes were involved in Complement and coagulation cascades, metabolism, Type II diabetes mellitus, Pathways in cancer etc.
