Abstract

Mitogenic properties have been demonstrated in vitro for the lysosomal acidic protease cathepsin-D (cath-D). We investigated possible relationships between cath-D cytosol cell content and tumor proliferative activity in a series of 129 operable breast cancer patients. For total cytosol cath-D evaluation, a solid phase two-site immunoradiometric assay was utilized on tumor cell cytosol obtained for hormone receptor assay (DCC method). The percentage of S-phase cells was analyzed by 3H-thymidine autoradiographic assay. Median 3H-thymidine Labeling Index (3H-Tdr-LI) of the series was 2.7%; median cath-D content resulted 57 pmol/mg of protein cytosol and was significantly higher in node-positive with respect to the node-negative subgroup (p
