However, there was no statistically significant difference in CDKN1B expression between the cancer tissues from diffuse large B-cell lymphoma (DLBC), acute myeloid leukemia (AML), SKCM, and testicular germ cell tumors (TGCT), all of which are lymphoid neoplasms (Fig. 1B). The gene discussed is CDKN1B; the disease is diffuse large B-cell lymphoma.
