BCL2 and neoplasm: In the melanoma tumor tissues of the CCR5−/− mice, the expression of NF-κB target cell death genes (Bax, caspase-3 and 9) and the DNA binding activity of NF-κB, were significantly inhibited, but the expression of cell death inhibitory NF-κB target genes, such as Bcl-2 and cIAP were enhanced.
