The purpose of this study was to evaluate the combined measurement of serum CEA, TPA, and CA 15-3, using an individual reference limit (IRL), for predicting distant metastases in asymptomatic women following a diagnosis of primary breast cancer.
We previously suggested that polypeptide N-acetylgalactosaminyltransferase 6 (GALNT6), which catalyzes O-type glycosylation of Mucin 1, might be a promising molecular target for drug development for breast cancer.
These results further the growing knowledge of the role of MUC1 in transcription, and suggest that the regulation of MUC1 in breast cancer may be more complex than previously appreciated.
These results identify a genetic mechanism responsible for MUC1 gene overexpression and support the hypothesis that a gene dosage effect of the long arm of chromosome 1 may be involved in the pathogenesis of breast cancer.
Detection of MUC1 and HS3ST2 promoter methylation status appears to be useful molecular markers for assessing the progressive state of the disease and could be helpful in discriminating breast cancer molecular subtypes.
While the malignant epithelial cells of pancreatic cancer show limited expression, in breast cancer tissue MUC1-ARF demonstrates strong nuclear expression.
The results of this study indicate that the mononuclear cells (MC) stimulated twice 1 week apart with MUC1 VNTR1 produced a greater specific killing of the breast cancer cell line MCF-7 than the 0, 1, 3 or 4 weekly stimulations.
This study was aimed to bioinformatics analysis and designing a recombinant chimeric protein containing MUC1 and HER2 antigens to express in prokaryotic host (Escherichia coli) as breast cancer diagnosis tools.
Several circulating mucinous markers, including CA 15.3, MCA, CA 459, CASA, and Truquant BR, are secreted products of the polymorphic MUC1 gene, and are used as diagnostic tools in patients with breast cancer.
Clinicopathological and Prognostic Significance of Cancer Antigen 15-3 and Carcinoembryonic Antigen in Breast Cancer: A Meta-Analysis including 12,993 Patients.
It is approved by FDA and EMA in association with tamoxifen or aromatase inhibitor (AI) and with fulvestrant and palbociclib in premenopausal women with hormone receptor (HR)-positive breast cancer.
In the current study, serum levels of the carbohydrate antigen 15-3 (CA 15-3) and carcinoembryonic antigen (CEA) were determined preoperatively in 364 breast cancer patients with no clinical signs of metastasis.
Their low sensitivity and specificity preclude the use of serum markers such as the MUC-1 mucin glycoproteins (CA 15.3, BR 27.29) and carcinoembryonic antigen in the diagnosis of early breast cancer.
In this work, carbon nanosphere (CNS)-based fluorescence "turn off/on" aptasensor was developed for targeted detection of breast cancer cell MCF-7 by conjugation with FAM (a dye)-labeled mucin1 (MUC1) aptamer P0 (P0-FAM), which can recognize MUC1 protein overexpressed on the surface of MCF-7.
Immunosensing of breast cancer tumor protein CA 15-3 (carbohydrate antigen 15.3) using a novel nano-bioink: A new platform for screening of proteins in human biofluids by pen-on-paper technology.
The MUC1 and EGP40 nested PCR were positive in 83.3% (10/12) and in 100% (33/33) respectively of BM from patiens with breast cancer who had no evidence of distant metastases.
