Pim2 expression is highly elevated in MM cell lines. (A) Pim2 mRNA is highly elevated in hematologic tumor cell lines. (B) Pim2 mRNA expression is most prominent in MM cell lines. (C) Pim2 protein expression is most prominent in MM cell lines. Pim2 protein expression was examined by immunoblotting in a panel of acute monoblastic leukemia (AML) cell lines and a panel of MM cell lines. ALL, acute lymphoblastic leukemia; CLL, chronic lymphocytic leukemia; CML, chronic myeloblastic leukemia; DLBCL, diffuse large B-cell lymphoma.
