1 Inhibition of NF-κB induces apoptosis of KSHV-infected primary effusion lymphoma cells by Shannon A. Keller, Elaine J. Schattner, and Ethel Cesarman Blood Volume 96(7):2537-2542 October 1, 2000 ©2000 by American Society of Hematology

2 NF-κB is constitutively activated in KSHV-infected PEL cell lines and patient specimens.(A), Nuclear proteins extracted from latent cultures of BC1, BC2, and BC3 cells were examined by EMSA for DNA binding using a radiolabeled NF-κB–specific probe.

3 The protein/DNA complexes in KSHV-positive PELs are primarily comprised of p65/p50 heterodimers and p50 homodimers.To assess the components of the protein/DNA complexes, nuclear proteins extracted from latent cultures of BC1, BC2, and BC3 cells were incubat...

4 Inhibition of constitutive NF-κB activity in BC3 cells.BC3 cells placed in culture at 7.5 × 105 cells/mL were treated for 1 hour with the inhibitors SN50 (A), CAPE (B), and Bay 11-7082 (C). Shannon A. Keller et al. Blood 2000;96:2537-2542 ©2000 by American Society of Hematology

5 Specific inhibition of NF-κB with Bay 11-7082.(A), The PEL cells BC1, BC2, BC3, and control BJAB cells were treated with Bay 11 and assessed for NF-κB and Oct-1/DNA binding. Shannon A. Keller et al. Blood 2000;96:2537-2542 ©2000 by American Society of Hematology

6 Decreased cell viability and the induction of apoptosis in PEL cells treated with Bay 11.BC1, BC2, BC3, and BJAB cells were placed in culture at 7.5 × 105 cells/mL without Bay 11 or with 5 μmol/L Bay 11 for 24 hours.
