These observations are consistent with our previous finding that exogenous bovine testicular hyaluronidase PH-20 enhances TNF cytotoxicity in various cancer cells, and that TGF-β1 blocks the increased TNF cytotoxicity [ 8 15 ] . As summarized in the Figure 8, the underlying mechanisms whereby Hyal-2 induces TNF cytotoxicity appear to be associated with 1) Hyal-2 induction of the proapoptotic WOX1, 2) Hyal-2 migration to the mitochondria during apoptosis, and 3) the prolonged period of IκBα degradation and NF-κB activation in TNF-treated Hyal-2-expressing cells.
It is unclear whether this extend ed period of IκBα degradation and NF-κB activation directly contributes to the ability of Hyal-2 to enhance TNF-mediated apoptosis.
Antisera against WOX1 were generated in rabbits against a synthetic peptide [ 10 ] . Antibodies against p53, IκBα, NF-κB p65 and α-tubulin were from Santa Cruz Biotechnology (Santa Cruz, CA) and Accurate Chemicals (Accurate Chemical, Westbury, NY).
IκBα is a physiological inhibitor of NF-κB activation; IκBα complexes with NF-κB and prevents its translocation to the nucleus [ 10 24 ] . NF-κB activation is believed to induce antiapoptotic proteins to block cell death [ 8 ] . However, in several studies activated NF-κB cannot protect cells from apoptosis [ 8 ] . Also, NF-κB appears to be essential in the p53-mediated apoptosis in tested cell lines [ 25 ] .
Preliminary studies on TNF-induced IκBα phosphorylation determined the optimum concentration for inhibition with infliximab.
