When both monocytes (which express αMβ2 and some CD54) and tumor cells were pre-treated with both P1 and P2 followed by sFn prior to assay (Bar2 +P1P2/+P1/P2) sFn inhibition was considerably reduced to a level which was not significantly different to the untreated control, as was also observed when cells were treated with peptides in the absence of sFn (Bar3; P1P2/P1/P2). This evidence concerns the gene ICAM1 and neoplasm.
