(Submitter supplied) FOXA1 and GATA3 can remodel chromatin accessibility, we further explored what effect of NR2F2 would have on chromatin properties. ATAC-seq (Assay for Transposase Accessible Chromatin with high-throughput sequencing) is widely used to map chromatin accessibility genome-wide. Thus, We perform ATAC-seq without oestrogen stimulation before and after NR2F2 depletion.Covalent modifications are a main chromatin property.To test whether NR2F2 favoured histone modification deposition on chromatin, we profiled ChIP-Seq of H3K4me1, H3K4me3, and H3K27ac following NR2F2 depletion in oestrogen-starved MCF-7 cells to gain comprehensive histone medication landscape.

(Submitter supplied) We show that most binding events of NR2F2 occur together with the ERα binding sites.To address the functional relationship between NR2F2 and ERα, we assessed the role of NR2F2 in oestrogen-induced growth in ER positive cell line MCF-7. The MTT experiment showed that inhibition of NR2F2 prevented the oestrogen-induced proliferation of MCF-7 cells.To further explore the effect of NR2F2 on estrogen response, We expanded our knockdown studies by performing RNA-seq analysis for MCF-7 cells transfected with control or NR2F2 shRNAs with or without E2.

(Submitter supplied) ERα binding activity largely depends on access to binding sites on chromatin, which is facilitated in part by Pioneer Factors (PFs).We show that most binding events of NR2F2 occur together with the ERα binding sites.To explore whether NR2F2 may act as potential pioneer factor of ER, we performed a series of ChIP-seq genome wide in MCF-7. Since NR2F2 associates with chromatin prior to estrogen treatment and its depletion in MCF-7 cells did not affect ERα expression, we hypothesize NR2F2 may inhibit estrogen-dependent growth by modulating ERα recruitment. more...

(Submitter supplied) Inactivating mutations in the MEN1 gene predisposing to the multiple endocrine neoplasia type 1 (MEN1) syndrome can also cause sporadic pancreatic endocrine tumors. MEN1 encodes menin, a subunit of MLL1/MLL2-containing histone methyltransferase complexes that trimethylate histone H3 at lysine 4 (H3K4me3). The importance of menin-dependent H3K4me3 in normal and transformed pancreatic endocrine cells is unclear. more...

(Submitter supplied) Although technological advances now allow increased tumor profiling, a detailed understanding of the mechanisms leading to the development of different cancers remains elusive. Our approach towards understanding the molecular events that lead to cancer is to characterize changes in transcriptional regulatory networks between normal and tumor tissue. Because enhancer activity is thought to be critical in regulating cell fate decisions, we have focused our studies on distal regulatory elements and transcription factors that bind to these elements. more...

(Submitter supplied) Estrogen Receptor (ER) is a steroid hormone receptor that regulates epithelial genes in breast cancer. ER forms a regulatory network with the other transcription factors, FOXA1 and GATA3. GATA3 is known to be capable of specifying chromatin localization of FOXA1 and ER. GATA3 has been identified as one of the most frequently mutated genes in breast cancer. However, how GATA3 mutations impact this transcriptional network is unknown. more...

(Submitter supplied) A pioneer transcription factor, GATA3, is one of the most frequently mutated genes in breast cancer, yet the impact of these mutations is largely unknown. We generated a GATA3 mutant cell line (T47D wt/R330fs) by CRISPR. Mutation of one allele of GATA3 led to loss of binding and decreased expression at a subset of genes, including Progesterone Receptor. At other loci, associated with epithelial to mesenchymal transition, gain of binding at a novel sequence motif correlated with increased gene expression. more...
