Results from functional assays demonstrated that the participation of XAV939 overturned the promotive impact of pcDNA3.1/ACTR2 transfection on the viability, migration, and invasion of DLBCL cells and the suppressive effect on DLBCL cell apoptosis (Figures 5(b)–5(f)). This evidence concerns the gene ACTR2 and diffuse large B-cell lymphoma.
