Genome wide profiling of PAX8 binding stes in PCCL3 rat cells

ABSTRACT: Analysis of PAX8 binding sites by chromatin immunoprecipitation coupled with ultra-high-throughput sequencing (ChIP-seq) in PCCL3 rat cells. Results provide insight into the contribution of this regulatory factor to transcription genome-wide. We generate a genome wide map of PAX8 binding sites in PCCL3 cells using as negative control an input DNA obtained just prior to Pax8 immunoprecipitation

<h4>Background</h4>The transcription factor Pax8 is essential for the differentiation of thyroid cells. However, there are few data on genes transcriptionally regulated by Pax8 other than thyroid-related genes. To better understand the role of Pax8 in the biology of thyroid cells, we obtained transcriptional profiles of Pax8-silenced PCCl3 thyroid cells using whole genome expression arrays and integrated these signals with global cis-regulatory sequencing studies performed by ChIP-Seq analysis<h ...[more]

ChIP-seq for PAX8 and histone modifications in Renal Cell Carcinoma cell lines.

Project description:In this experiment we analyzed the genome wide occupancy of PAX8 by ChIP-seq in four Renal Cell Carcinoma cell lines. Additionally we performed ChIP-seq also for histone modifications correlated with transcriptional activity (H3K27ac), enhancers (H3K4me1) and promoters (H3K4me3). Unrelated IgG was used as a background noise control.

Glis3 regulates the expression of thyroid hormone synthetic genes in coordination with other thyroid transcription factors

Project description:Comparison of cistromes from PAX8, NKX2.1, and FOXE1 ChIP-Seq analysis using mouse thyroid gland and rat thyrocyte PCCl3 cells revealed that there is a significant overlap between GLIS3 binding regions and those of PAX8, NKX2.1, and FOXE1 in genes associated with thyroid hormone biosynthesis.

Lineage factor-dependent signalling by kidney cancer-associated genetic alteration

Project description:As shown by large-scale human genetic data, cancer mutations display strong tissue-selectivity, but how this selectivity arises remains unclear. Here, using experimental models, functional genomics and analysis of patient samples, we demonstrate that the lineage transcription factor paired box 8 (PAX8) is required for oncogenic signalling by two common clear cell renal cell carcinoma (ccRCC)-causing genetic alterations in humans: the germline variant rs7948643 at 11q13.3 and somatic inactivation of the von Hippel-Lindau tumour suppressor (VHL). VHL loss, observed in ~90% of ccRCCs, can lead to hypoxia-inducible factor 2 alpha (HIF2A) stabilization. We show that HIF2A is preferentially recruited to PAX8-bound transcriptional enhancers, including a pro-tumorigenic cyclin D1 (CCND1) enhancer that is controlled by PAX8 and HIF2A. The ccRCC protective allele C at rs7948643 inhibits PAX8 binding at this enhancer and downstream activation of CCND1 expression. Co-option of a PAX8-dependent physiological programme that supports proliferation of normal renal epithelial cells is also required for MYC expression from the ccRCC metastasis-associated amplicons at 8q21.3-q24.3. These results demonstrate that transcriptional lineage factors are essential for the expression of canonical oncogenes and they mediate tissue-specific cancer risk associated with somatic and inherited genetic variants

Gene expression profile changes upon knock-down of Pax8

Project description:In order to define the transcriptional network functionally regulated by Pax8 as well as infer its direct targets, we performed RNAi to knock-down Pax8 gene in FRTL-5 thyroid cells. Expression data from three independent silencing experiments were analyzed by microarray technology unraveling 2815 genes differentially expressed between silenced cells and controls. Of these, 1421 genes were down-regulated and 1394 genes were up-regulated 72hrs after Pax8 silencing. The results obtained suggest that Pax8 regulates numerous pathways, some of which involved in the regulation of cell cycle, thyroid cancer and apoptosis, thus confirming that Pax8 is a master regulatory gene. Rat differentiated thyroid cells from FRTL-5 line were transfected with siGENOME Pax8 siRNA (siPax8, experimental) or siGENOME Non-Targeting siRNA (ntPax8, controls). The trascriptome from three siPax8 biological replicates, 72 hours after transfection, was compared to the trascriptome from 3 control ntPax8 biological replicates. Microarray analysis was performed at gene-level using the AffymetrixGeneChip Rat Gene 1.0 ST array

Epigenomic remodeling of the PAX8 cistrome in high grade serous ovarian cancer [RNA-Seq]

Project description:We report mapping of the PAX8 cistrome in three high grade serous ovarian cancer cell lines (KURAMOCHI, OVSAHO, and JHOS4) compared to three benign immortalized fallopian tube cell lines (FT33, FT194, and FT246). We identified a highly conserved PAX8 binding pattern common across benign fallopian tube cell lines that was distinct from the unique PAX8 binding patterns seen in each cancer cell line. Comparison of benign and malignant Mullerian cell lines with and without PAX8 knockdown. For each cell line, three distinct siRNAs targeting PAX8 plus a pool of all three siRNAs were examined and compared to both a non-transfected control as well as a control transfected with a non-targeting siRNA.
