Establishment and characterization of HER2-positive cell line derived from pleural effusion of human breast scirrhous carcinoma.
We have established a cell line derived from a pleural effusion of breast scirrhous carcinoma. This cell line presented immunohistochemically negative for estrogen receptor and slightly positive for progesterone receptor, and positive for c-erbB/HER2/neu. However the original tumor was found to be positive for estrogen receptor and progesterone receptor and slightly positive for c-erbB/HER2/neu expression. Enzyme and electrochemiluminescence immunoassays of tumor markers in the conditioned medium by the cell line revealed they secrete CA15-3, NCC-ST-439 and HER2 protein. We believe the cell line will contribute to the therapeutic study of malignant breast cancer.
