Abstract:
:We investigated the expression of fos oncogene proteins in lymphoproliferative disorders, using a monoclonal antibody (FO-120) that was prepared against a synthetic oligopeptide of fos protein (amino acid sequence from 127 to 152). Although peripheral blood leukocytes were rarely positive for FO-120, they were transiently stained after lectin (PHA) stimulation. After culture with IL-2 for 1 or 2 weeks, less than 40% of the lymphocytes weakly reacted with FO-120, whereas strongly positive cells were detected in more than 70% of cells in half the T-cell lines established from preleukemic state of adult T-cell leukemia (pre-ATL) and all of ATL derived T-cell lines. All in vivo specimens of non-Hodgkin's malignant lymphomas, except for one case of T-cell lymphoma were also strongly positive. In addition, the extent of the antibody reactivity correlated with the histopathological grade of malignancy in B-cell lymphoma. The reactivity to most AILD-IBL lesions overlapped with that to T-lymphomas, and could be distinguished from that to reactive lesions. FO-120 appears to be a useful tool for detecting early neoplastic changes in lymphoproliferative disorders.
