The histopathology of 12 patients with adenoma of the ampulla of Vater was examined to trace the adenoma-carcinoma sequence of the ampulla of Vater. Immunohistochemistry for carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 was also performed. Four large adenomas with mild dysplasia also had foci of moderate dysplasia while another one contained foci of severe dysplasia (intramu...

Copyright © 2011. Korean Society of Obstetrics and Gynecology Cervical carcinoma is the third most common cancer in women, and the seventh overall, with an estimated 530,000 new cases in 2008 [1] and the one of the most lethal female malignancies in developing countries [2]. Cervical carcinoma can be categorized into subtypes according to histological classification, of which invasive squamous ...

It is widely believed that antigen heterogeneity and noninternalization of antigen-antibody complexes will severely limit the antitumor activity of monoclonal antibody-drug conjugates. The B72.3 monoclonal antibody binds to a tumor-associated antigen which is heterogeneously expressed in human carcinomas (J. Schlom, Cancer Res., 46: 3225-3238, 1986). We therefore performed studies to assess the...

Cell lines derived from human small cell carcinoma of the lung express high levels of a surface polypeptide termed the cluster-w4 antigen, which was previously identified as a potential target for toxin-based immunotherapy of lung cancer. We have cloned a complementary DNA encoding the cluster-w4 antigen from COS-1 fibroblasts transfected with a SW2 small cell carcinoma library, by panning with...

Cell lines derived from human small cell carcinoma of the lung ex press high levels of a surface polypeptide termed the cluster-w4 antigen, which was previously identified as a potential target for toxin-based immunotherapy of lung cancer. We have cloned a complementary DNA encoding the cluster-«-! antigen from COS-1 fibroblasts transfected with a SW2 small cell carcinoma library, by panning w...

We developed a new quantitative method for detecting abnormal glycolipid expression in endometrial cells using a monoclonal antibody (MSN-1) and analyzed the glycolipid antigen recognized by MSN-1 in 173 clinical endometrial cell samples (66 normal endometria, 39 endometrial hyperplasias, and 68 endometrial adenocarcinomas). The mean glycolipid antigen levels in normal endometrium, endometrial ...

Abstract The objective of this paper is to present the sensor platforms for alpha-fetoprotein (AFP), detection which a biomarker Hepatocellular carcinoma. experiments were designed investigate various AFP via surface Plasmon resonance (SPR) technique. In each step immobilization, antiAFP-AFP interaction and enhancing signal platform was used without fluorescent labelling on ultra-thin film chip...

A unique mouse hybridoma, PR92, was obtained using human prostate adenocarcinoma cell line DU145. The monoclonal antibody produced by the PR92 clone was reactive with DU145, MCF-7 (breast adenocarcinoma), and CHAGO (lung carcinoma), but not with normal cell lines and 16 other cell lines of cancerous origin. A homologous solid-phase sandwich radioimmunoassay (PR92-RIA) was developed utilizing PR...
