PTEN and diffuse large B-cell lymphoma: For example, GCB cell lines OCI-LY1 and WSU-DLCL2 shared mutations in BCL2, EZH2, deletion/inversion of PTEN, and FOXO3/PDGFD translocations, and these cell lines may possibly follow a similar course (e.g., PI3K-AKT signaling) to DLBCL tumorigenesis because of their shared genetic profile.
