on a molar basis , the inhibitors of chymotrypsin appear to be the most effective protease inhibitors at suppression of radiation-induced transformation in vitro , ( ii ) the protease inhibitors antipain and the bowman-birk ( soybean ) protease inhibitor have no effect on radiation transformation when present only during irradiation , ( iii ) the protease inhibitor antipain can suppress radiation transformation in vitro when applied to proliferating `` '' initiated ' cells as late as 10 days and 13 cell divisions post-irradiation , and ( iv ) tpa treatment following a 10-day protease inhibitor ( anti-pain ) exposure of x-irradiated `` '' initiated ' cells does not lead to promotion in vitro .
