However, when we validated by qRT-PCR, some of the genes, selected also based upon their potential relevance for DLBCL biology [29,30,31,32,33,34,35], CD52, FCMR, RGS1, and HCST, were all confirmed as downregulated after ETS1 knockdown (Figure 1). This evidence concerns the gene RGS1 and diffuse large B-cell lymphoma.
