HiChIP data in A673 & TC71 Ewing cell lines (STAG1 and STAG2 knock-out)

Project description:STAG2, a member of cohesin, is one of the most recurrently mutated genes in human cancer. Here, we investigated STAG2 function in the context of Ewing sarcoma. Using a CRISPR/Cas9 approach, we generated two STAG2 knock-out isogenic clones (A673_SA2m#1 and TC71_SA2m#2) derived from A673 and TC71 STAG2 wild type (WT) Ewing sarcoma cell line. A STAG2 rescue model (A673_SA2r) was generated by correcting the CRISPR mutation in the A673_SA2m#1 model. These STAG1/2 proficient and deficient models were profiled by CTCF HiChIP experiments. STAG2 isogenic models were also profiled by H3K27ac HiChIP experiments. Analyses of HiChIP data allowed to show that STAG2 promotes CTCF-anchored loop extrusion and cis-promoter and -enhancer interactions.

ChIP-seq data in A673 & TC71 Ewing cell lines (STAG1 and STAG2 knock-out)

Project description:STAG2, a member of cohesin, is one of the most recurrently mutated genes in human cancer. Here, we investigated STAG2 function in the context of Ewing sarcoma, an aggressive bone tumor driven by EWS-FLI1 oncogene chimeric transcription factor. Using a CRISPR/Cas9 approach, we generated three STAG2 knock-out isogenic clones (A673_SA2m#1, TC71_SA2m#1 and TC71_SA2m#2) derived from A673 and TC71 STAG2 wild type (WT) Ewing sarcoma cell line. Similarly, a STAG1 knock-out isogenic clone (A673_SA1m#1) was generated. Finally, a STAG2 rescue model (A673_SA2r) was generated by correcting the CRISPR mutation in the A673_SA2m#1 model. These STAG1/2 proficient and deficient models were profiled by ChIP-seq for EWS-FLI1, CTCF, cohesin members, and histone marks and allowed to highlight a global conservation of binding for these marks upon STAG2 mutation.

RNA-seq data in A673 & TC71 Ewing cell lines (STAG1 and STAG2 knock-out and proficient models and silenced for EWS-FLI1)

Project description:STAG2, a member of cohesin, is one of the most recurrently mutated genes in human cancer. Here, we investigated STAG2 function in the context of Ewing sarcoma, an aggressive bone tumor driven by EWS-FLI1 oncogene chimeric transcription factor.

A STAG2 rescue model (A673_SA2r) generated by correcting the CRISPR mutation in the A673SA2m#1 model was also profiled using RNA-seq. Comparison of RNA-seq data allowed highlighting a broad transcriptional modulation upon STAG2 knock-out. In addition, we compared these analyses with STAG1 knock-out A673 derived model (A673SA1m#1) and with A673 (WT) and TC71 (WT) parental cells lines transfected with siCT or siEWS-FLI1.

The effect of STAG2 loss in Ewing sarcoma

Project description:SMC1a HiChIP was performed for the Ewing sarcoma cell line A673 under two conditions: 1) cells treated with non-targeting CRISPR Cas9 guides or 2) STAG2-targeting CRISPR Cas9 guides. Cells treated for gene editing were clonally selected and confirmed to either express STAG2 (control condition) or have loss of STAG2 expression (STAG2 loss condition). For the control condition, we used the cell clones A673.sgNT-1c4 and the STAG2 knockout clone A673.sgSTAG2-1c6. HiChIP was performed for each clone in duplicate.

The effect of STAG2 loss in Ewing sarcoma [HiChIP]

Project description:Ewing sarcoma is an aggressive malignancy characterized by oncogenic rearrangements of the EWS gene with an ETS-family transcription factor, most commonly FLI. Recent comprehensive next-generation sequencing efforts have revealed few other highly recurrent mutations in this disease apart from loss-of-function mutations in STAG2 which occur in 15-20% of tumors. STAG2 is a member of the cohesin complex, which regulates sister chromatid alignment during mitosis and epigenetic regulation of gene expression. While some studies suggest that loss of STAG2 is associated with the development of aneuploidy, this is not the case in Ewing sarcoma. To investigate whether STAG2 loss affects epigenetic regulation of gene expression in Ewing sarcoma, we developed isogenic Ewing sarcoma cell lines with STAG2 knockout. We found that Ewing sarcoma cells engineered for loss of STAG2 maintain an intact cohesion complex that alternately incorporates STAG1.
