Project description:Ewing sarcomas harbor few mutations beyond the chromosomal translocation that initiates disease and the mechanistic basis for the metastasis of these tumors remains poorly understood. The epigenome of Ewing sarcoma (EWS) cells reflects the regulatory state of genes associated with the DNA binding activity of the fusion oncoproteins EWSR1::FLI1 or EWSR1::ERG. In this study, we examined the repressive activities of the EWSR1::FLI1/ERG fusion oncoproteins. Focusing on one of the repressed EWSR1::FLI1/ERG target genes, ETS1, we detected EWSR1::FLI1 binding and a H3K27me3 repressive mark at this locus. Depletion of EWSR1::FLI1 results in ETS1’s binding of promoter regions, and we show ETS1 regulates the expression of multiple proteins that function in extracellular matrix organization including TENSIN3 (TSN3). Interestingly, TSN3 expression in EWS tumors significantly correlates with that of ETS1 (0.85, FDR <0.01). TNS3 is a focal adhesion protein that contributes to tumor cell migration by connecting the cytoplasmic tail of integrins to the actin cytoskeleton. EWS cell lines, in which we activated ETS1 expression (CRISPRa) exhibited increased TNS3 expression and a migratory phenotype. Critically, the activated ETS1 EWS cell lines show TNS3 accumulation at leading cell edges, with F-actin cytoskeletal reorganization, a phenotype associated with cell migration.

Project description:Beige adipocytes accumulates mitochondria and alleviates metabolic disorder via activating energy expenditure. Whether the opposing process of mitochondrial biogenesis and clearance are integrated regulated in beige adipocytes is beyond known. Here we show that DNA binding protein Ets1 suppresses beige adipocyte formation via bidirectional regulation of mitochondrial biogenesis and clearance. The expression level of Ets1 was down-regulated in browning adipocytes, and up-regulated in the subcutaneous fat of obese mice. Adipocyte Ets1 heterozygous knock-in mice showed suppressed beige adipocytes formation under cold stress, while the homozygous knock-in mice are cold intolerance. On the other hand, knocking out Ets1 in adipocytes enhanced energy expenditure and protect the mice from high fat diet induced metabolic disorders. Mechanical assay suggests Ets1 binds to the promoter region of mitochondria complex coding genes and autophagy related genes, transcriptionally suppresses mitochondrial biogenesis and activates its clearance. Our results indicate that Ets1 integrally regulates the balance of mitochondria generation and degradation, hence acts as a pivotal governor of mitochondria content and negatively regulates beige adipocyte formation.

Project description:Ets1 can directly bind key TFH genes, regulating their expression . Loss of Ets1 results in the pre-mature expression of TFH-genes in Non-TFH cells. We wished to analyze if loss of Ets1 correlated with changes in chromatin accessibility especially in TFH gene loci.

Project description:Ets1-/- mice have an increase in B cell differentiation to plasma cells and increased serum immunoglobulin levels. The genes in B cells that are transcriptionally regulated by Ets1 and help regulate B cell differentiation are largely unknown. Here, we identify Ets1-regulated target genes in B cells using ChIP-seq and RNA-seq analysis. We found that Ets1 targets genes associated with immune response, mature B cell differentiation and regulation of B cell activation.
