Many investigations have shown that the targeted inhibitors of crucial tyrosine kinases in BCR signaling pathway, such as Syk inhibitor PRT060318 and the inhibitor of Src family kinases (SFKs) dasatinib, could prevent the proliferation of GCB-DLBCL cell lines by causing cell-cycle arrest or inducing cell apoptosis [30,31]. This evidence concerns the gene BCR and diffuse large B-cell lymphoma.
