Abstract

The identification and characterization of risk factors and their molecular implications in the pathophysiology of human diseases such as cancer is essential for designing efficient diagnostic assays and therapeutic compounds. Estrogenic steroids, under normal physiological conditions, have been shown to play a critical function in several tissues.
The response of such a variety of tissues to estrogen stimulation can explain in part its active role in the development and progression of different human diseases, particularly breast cancer. Searching for estrogen-responding cellular factors in parental cells of primary human breast carcinomas obtained from tumour biopsies, two cellular markers, an isoenzyme of putative leucine aminopeptidase (LAPase; EC 3.4.11.1) from parental cells of primary humor breast carcinomas obtained from tumour biopsies, and cytosolic NDP-Kinase/Nm23 (EC 2.7.4.6) from HL60 cells were identified. Monoclonal antibodies against each cellular marker have been produced. Determination of the presence of these two markers, either alone or in combination, can be used to detect breast cancer, and in particular, associated metastatis. Thus, this invention refers to the use of both LAP and NDP-Kinase/Nm23 monoclonal antibodies together in a tandem solid-matrix based immuno-assay for first line confimatory blood-based testing for breast cancer.
