Understanding the mechanism of tumor resistance is critical for cancer therapy. In this study, we investigated the effect of carcinoembryonic antigen (CEA) overexpression on UV-and 5-fluorouracil (5-FU)-induced apoptosis and autophagy in colorectal cancer cells. We used histone deacetylase (HDAC) inhibitor, NaB and DNA demethylating agent, 5- azacytidine (5-AZA) to induce CEA expression in HT29...

Carcinoembryonic antigen (CEA) is heterogeneous and may represent a set of closely related glycoproteins which have been referred to as isomeric species of CEA. The existence of other CEA-related glycoproteins such as non-specific cross reacting antigen (NCA) has been recognized. Recently a highly purified homogeneous isomeric species of CEA described as CEA-S has shown differences in diagnosti...

Carcinoembryonic antigen (CEA) is a well-characterized oncofetal glycoprotein whose overexpression by human adenocarcinomas has been a target for cancer immunotherapy. Limited information is available regarding the ability of patients to mount an antibody response to this self-antigen following vaccination. Recombinant vaccinia viruses encoding full-length or internally deleted cDNAs for human ...

BACKGROUND Symptomatic or asymptomatic patients with significant carotid artery stenosis (range, 70% to 99%) generally undergo either carotid artery endarterectomy (CEA) or carotid artery stenting (CAS) to prevent stroke. In this study, we evaluated the cost effectiveness of these two treatment modalities. METHODS A total of 47 patients (mean age, 67.1±9.1 years; male, 87.2%) undergoing eithe...

Clinical trials have demonstrated that the risk of developing atopic dermatitis is reduced when using hydrolysed formulas to feed infants with a documented risk of atopy (i.e. an affected parent and/or sibling)when breastfeeding is not practised. However, little is known about the cost-effectiveness of using hydrolysed formulas. Consequently, economic analyses in 5 European countries (Denmark, ...

We recently cloned members of the murine carcinoembryonic antigen (CEA) gene family, some of which are differentially expressed during placental development. By intra- and interspecies sequence comparisons, we identified an element in the putative promoter and/or 5'-nontranslated region which is conserved within all human and rodent CEA-related genes analyzed so far. Using gel retardation analy...

BACKGROUND We previously reported results of a prospective trial evaluating the significance of circulating tumor cells (CTCs) in patients with metastatic colorectal cancer (mCRC). This secondary analysis assessed the relationship of the CTC number with carcinoembryonic antigen (CEA) and overall survival. PATIENTS AND METHODS Patients with mCRC had CTCs measured at baseline and specific time ...

Using an assay based on the binding of a carcinoembryonic antigen (CEA)-specific monoclonal antibody, we have examined the expression of carcinoembryonic antigen genes in human colon tumor and normal fibroblast cell lines. CEA expression was not detectable in the normal fibroblast cell lines, whereas varying levels of high CEA expression were found in the colon tumor cell lines LS-174T, GEO, an...

BACKGROUND Carcinoembryonic antigen (CEA) as a marker in the follow-up after curative resection of colorectal carcinoma (CRC) is often omitted from follow-up despite guideline recommendations. One reason is the assumption that when a normal CEA value exists before curative resection of CRC, it will neither rise during follow-up. This study investigates this relationship. METHOD Data were deri...
