Project description:The glucocorticoid receptor (GR) recruits many coregulators via the well characterized AF2 interaction surface in the GR ligand binding domain, but LIM domain coregulator Hic-5 binds to the relatively uncharacterized tau2 activation domain in the hinge region of GR. Requirement of Hic-5 for glucocorticoid-regulated gene expression in U2OS osteosarcoma cells was defined by Hic-5 depletion and global gene expression analysis. Hic-5 depletion had selective and dramatic effects, positive and negative, on both activation and repression of GR target genes. For some hormone-induced genes, Hic-5 facilitated recruitment of the Mediator complex and RNA polymerase II. In contrast, many genes were not regulated by hormone until Hic-5 was depleted. On these genes Hic-5 acted at a very early step of the regulatory process, preventing efficient GR binding on enhancers, chromatin remodeling, and thus preventing glucocorticoid-driven transcriptional regulation. Overall, Hic-5 has selective and diverse roles on GR target genes, functioning as coactivator on some genes and corepressor on others, and either facilitating or opposing the glucocorticoid-driven actions of GR. Hic-5 exhibits multiple mechanisms of action, either regulating GR binding to DNA and chromatin remodeling, or facilitating later steps in transcription complex assembly. We investigate the relationship between GR and Hic5 and identify classes of genes that respond differently when cells are induced with hormone and when Hic5 is knocked down We knock down Hic-5 (TGFB1I1) in U2OS cells using siRNA (siHic5_2) along with nonspecific siRNA (shNS) and assay gene expression changes at 4 different time points of hormone treatment. We also include non-infected control (NI) as a second control at each time point.

Project description:This dataset consists of in situ HiC-seq data from a human oesophageal adenocarcinoma cell line (OE19). In total, the dataset includes 2 biological replicated samples. The Hi-C sample and library preparations were generated using Arima-HiC Kit (A510008, ARIMA Genomics) and Arima Library Prep module (A303011, ARIMA Genomics), respectively.

Project description:Identifying the effect of the co-regulator Hic-5 (TGFB1I1) and TGFB on the transcriptional profile of WPMY human prostate fibroblast cells with view to further elucidating the broader biological role of Hic-5 and TGFB on fibroblast. Knockdown of Hic5 for 48 hours in PShTert-AR cells significantly altered the androgen regulation of approximately 1347 genes. The effect of Hic-5 knockdown was to suppress androgen regulation of approximately 85% of those transcripts, by either reducing androgen mediated repression or activition of gene expression. Isogenic WPMY-1 fibroblasts stably transfected with short-hairpin RNA against Hic-5 or transfected with non-specific negative control short-hairpin RNA, were kept in 5% hormone stripped FBS RPMI for 48 hours and subsequently treated with either ethanol vehicle control or TGFB for 16hr. Total RNA was extracted. Five independent vehicle and five TGFB siSCR and siHic5 samples were hybrydised to Affymetrix Human Gene 1.0 ST array chips.

Project description:Nude mice were allografted with medulloblastoma tumors derived from Ptch+/-HIC+/- transgenic mouse and treated with vehicle or NVP-LDE225. RNA was prepared from tumours from vehicle or NVP-LDE225 treated nude mice allografted with medulloblastoma tumors derived from Ptch+/-HIC+/- transgenic mouse and hybridized on the Affymetrix Mouse Genome 430A 2.0 RNA expression microarray.

Project description:In addition to central functions in cell adhesion signalling, integrin-associated proteins have wider roles at sites distal to adhesion receptors. In experimentally defined adhesomes, we noticed that there is clear enrichment of proteins that localise to the nucleus, and conversely, we now report that nuclear proteomes contain a class of adhesome components that localise to the nucleus. We here defined a Hic-5-proximal subproteome that localises to the nucleus.

Project description:Identifying the effect of the co-regulator Hic-5 (TGFB1I1) on global androgen receptor transcriptional activity in PShTert-AR prostate fibroblast cells with view to further elucidating the broader biological role of Hic-5 on fibroblast spceific androgen signaling. Knockdown of Hic5 for 48 hours in PShTert-AR cells significantly altered the androgen regulation of approximately 1347 genes. The effect of Hic-5 knockdown was to suppress androgen regulation of approximately 85% of those transcripts, by either reducing androgen mediated repression or activition of gene expression. PShTert-AR cells were transfected with 10nM non-specific control siRNA (NS) or with commercially avaliable Hic-5 specific siRNA (siHic5) for 24hrs. Cells were kept in 5% hormone stripped FBS RPMI for a further 24 hours and subsequently treated with either ethanol vehicle control or 10nM DHT for 16hr. Total RNA was extracted. Nine independent vehicle and 9 DHT siNS and siHic5 samples were pooled into three groups of vechicle and DHT treated siNS and siHic5 samples and hybrydised to Affymetrix Human Gene 1.0 ST array chips.
