Effects of anti-nuclear factor kappa B reagents in blocking adhesion of human cancer cells to vascular endothelial cells.

Transcription factor nuclear factor kappa B (NF kappa B) controls gene expression of a number of genes including cell adhesion molecules such as E-selectin, intercellular adhesion molecule 1, and vascular adhesion molecule 1. These cell adhesion molecules are known to play important roles in a critical step of tumor metastasis, arrest of tumor cells onto the venous or capillary bed of the target organ. NF kappa B is activated by extracellular signals such as those elicited by proinflammatory cytokines, tumor necrosis factor and interleukin 1 ( IL-1). Here we demonstrate that IL-1 beta induces nuclear translocation of NF kappa B in human umbilical vein endothelial cells, followed by induction of cell surface expression of E-selectin, intercellular adhesion molecule-1, and vascular adhesion molecule 1, and subsequently augments adhesion of those cancer cells expressing sialyl Lewis X antigen, a ligand to E-selectin. We have also demonstrated that the adhesion of tumor cells to IL-1 beta-treated human umbilical vein endothelial cells can be inhibited by anti-NF kappa B reagents such as N-acetyl L-cysteine, aspirin, or pentoxifylline. These observations indicate the involvement of NF kappa B in cancer metastasis and the feasibility of using anti-NF kappa B reagents in preventing metastasis.[1]
