Evaluation of a novel fluorescent nanobeacon for targeted imaging of Thomsen-Friedenreich associated colorectal cancer
The Thomsen-Friedenreich (TF) antigen represents a prognostic biomarker of colorectal carcinoma. Here, using a nanobeacon, the surface of which was fabricated with peanut agglutinin as TF-binding molecules, we demonstrate that the nanobeacon is able to detect TF antigen in frozen and freshly biopsied polyps using fluorescence microscopy. Our results provide important clues about how to detect a...
متن کاملFluorescence-based endoscopic imaging of Thomsen-Friedenreich antigen to improve early detection of colorectal cancer.
Thomsen-Friedenreich (TF) antigen belongs to the mucin-type tumor-associated carbohydrate antigen. Notably, TF antigen is overexpressed in colorectal cancer (CRC) but is rarely expressed in normal colonic tissue. Increased TF antigen expression is associated with tumor invasion and metastasis. In this study, we sought to validate a novel nanobeacon for imaging TF-associated CRC in a preclinical...
متن کاملAnalysis of human tumor associated Thomsen-Friedenreich antigen.
The Thomsen-Friedenrich (TF) antigen is a precursor structure of MN blood group antigens and is also expressed by about 90% of human carcinomas. The immunodominant group of TF antigen [beta-galactosyl(1-3)-alpha-N-acetylglactosamine] is present in cryptic form in normal RBC and is revealed by neuraminidase treatment. A murine monoclonal antibody (Mab 49H.8) developed against neuraminidase treat...
متن کاملThe role of the Thomsen-Friedenreich antigen as a tumor-associated molecule.
The Thomsen-Friedenreich antigen (Gal-GalNAc) represents a tumor-associated molecule, which is assumed to be one of the few chemically well-defined antigens with a proven association with malignancy. In order to analyze the role of the carbohydrate structure Gal-GalNAc for gastrointestinal tumors, we immunized Balb/c mice with MCF-7 breast tumor cells together with synthetic Gal-GalNAc linked t...
متن کاملImmunodiagnostic potential of mucin (MUC2) and Thomsen-Friedenreich (TF) antigens in Egyptian patients with colorectal cancer.
OBJECTIVE Colorectal cancer (CRC) is more common in developed countries and is the third most common cancer among both men and women. CRC provides an attractive model of tumour biology with normal mucosa to adenoma to carcinoma sequence. The TF-antigen (Thomsen-Friedenreich) can be identified by galactose oxidase-Schiff's (GOS) reaction either on tissues or on rectal mucus samples from patients...
