Study on Nuclear Matrix Proteins from Human Breast Carcinoma

Objective To investigate the marker protein of human breast carcinoma from nuclear matrix proteins (NMPs). Methods NMPs were injected subcutaneously into rabbit to get antiserum, which was used to detect the NMPs specificity for breast carcinoma. Results There was an apparent positive band (100 kD) in the NMPs of breast carcinoma, which did not exist in normal breast and other tumors that were detected. Conclusion One or one group of 100 kD NMPs were found to be related to human breast carcinoma, which may be involved in the carcinogenesis and development of human breast carcinoma and valuable for breast carcinoma diagnosis.
