Genetically determined polymorphism of the circulating human breast cancer-associated DF3 antigen.
The murine monoclonal antibody (MAb) DF3 was prepared against a human breast carcinoma. Previous studies have demonstrated that DF3 antigen levels are elevated in plasma of patients with breast cancer. Furthermore, MAb DF3 reacts with circulating glycoproteins of different molecular weights ranging from approximately 300 to 450 kd. The present study demonstrates that plasma DF3 antigen is compr...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولFrequent alteration of the DF3 tumor-associated antigen gene in primary human breast carcinomas.
The gene for the human DF3 breast carcinoma-associated antigen contains a conserved (G + C)-rich 60-base pair tandem repeat and maps to chromosome 1q21-24. In the present study we isolated and characterized 1220 base pairs of nonrepetitive adjacent sequences. Multiple alleles were identified by fragment size. Signal intensity of hybrids with the tandem and unique sequence probes indicated that ...
متن کاملIsolation and sequencing of a cDNA coding for the human DF3 breast carcinoma-associated antigen.
The murine monoclonal antibody (mAb) DF3 reacts with a high molecular weight glycoprotein detectable in human breast carcinomas. DF3 antigen expression correlates with human breast tumor differentiation, and the detection of a cross-reactive species in human milk has suggested that this antigen might be useful as a marker of differentiated mammary epithelium. To further characterize DF3 antigen...
متن کاملUse of a murine monoclonal antibody for detection of circulating plasma DF3 antigen levels in breast cancer patients.
The murine monoclonal antibody (MAb), designated DF3, reacts with a 300,000-mol wt mammary epithelial antigen. A sequential double-determinant radioimmunoassay (RIA) has been developed to monitor circulating DF3 antigen. Using this assay, we have demonstrated that 33 of 36 normal women had plasma RIA antigen levels less than 150 U/ml. In contrast, 33 of 43 patients (76%) with metastatic breast ...
