Abstract: | Rabbit antibodies to the nuclear Tris extract of HeLa cells which have been shown by the indirect immunofluorescence technique to localize in nucleoli of a variety of human malignant tumors but not in a number of nontumor tissues also produced bright fluorescence in nucleoli of tumor cells in several hematological malignancies. The tumors studied included Hodgkins malignant lymphoma, non-Hodgkins malignant lymphoma, acute myeloid and acute myelomonocytic leukemia, chronic lymphatic and chronic myeloid leukemia. In contrast, none of the corresponding normal cell lines in the bone marrow exhibited bright nucleolar fluorescence. In addition, neither the cells of patients with acute infectious mononucleosis nor lymphoid hyperplasia exhibited bright nucleolar fluorescence. These studies suggest that antibodies to HeLa cell nucleolar antigens may be useful in immunodiagnosis of human malignancies. |
