Project description: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

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.
Project description:A chromosomal translocation results in production of an oncogenic PAX8-PPARG fusion protein (PPFP) in a subset of thyroid carcinomas. PAX8 is an important thyroid transcription factor, and PPARG is a transcription factor that plays important roles in the biology of adipocytes and macrophages, but has no known function in the thyroid. PPFP retains the DNA binding domains of both proteins. However, the genomic DNA binding sites of PPFP have not been identified, and only limited data exist to characterize gene expression in PPFP thyroid carcinomas. Therefore, we expressed PPFP in PCCL3 rat thyroid cells and used ChIP-seq to identify PPFP genomic binding sites (PPFP peaks) and RNA-seq to characterize PPFP-dependent gene expression. The genome contains ~20 000 PPFP peaks, including known PAX8 and PPARG binding sites, indicating that both DNA binding domains are functional. PPFP binds to and regulates many genes involved in cancer-related processes such as development and cell division. PPFP also binds to and regulates many genes related to mitochondria and lipid metabolism that are regulated by PPARG in adipocytes. Our data highlight the complexity of PPFP as a transcription factor and the numerous ways that it regulates thyroid oncogenesis.
Project description:In order to establish a rat embryonic stem cell transcriptome, mRNA from rESC cell line DAc8, the first male germline competent rat ESC line to be described and the first to be used to generate a knockout rat model was characterized using RNA sequencing (RNA-seq) analysis.
