In all the RT-DLBCL cells, their mRNA levels, determined by scRNA-Seq, also generally corresponded with the protein levels of BCL2 family of proteins, including BCL2, MCL1, Bcl-xL, BAX, BAK, BIM (BCL2L11), as well as with the protein expression of c-IAP2 (BIRC3), XIAP, and Ki67 (MKI67). This evidence concerns the gene BIRC3 and diffuse large B-cell lymphoma.
