STAT3 and diffuse large B-cell lymphoma: Higher levels of STAT3 mRNA was detected in the non-GCB subtype than the GCB subtype using DLBCL cell lines [22, 28] and pSTAT3 appeared to bind to promoters of different genes in each subtype, wherein genes regulating cell proliferation and survival are mostly upregulated in non-GCB DLBCL [28].
