ACVR1 and lymphoma: Through the differentially expressed genes (DEG) and GO analysis using RNA‐seq data from WSU‐DLCL2 lymphoma cell carrying EZH2Y641F, we observed an enrichment of TGF‐beta pathway with PRC2 inhibitor treatment, with BMP7 and ACVR1 as the top DEGs and multiple BMP ligands upregulated (Figure 2A).
