CEACAM5 (carcinoembryonic antigen-related cell adhesion molecule 5) is a member of the CEACAM receptors, which in turn belong to immunoglobulin (Ig) superfamily. Its N-terminal contains an Ig variable-region-like domain, which is succeeded by multiple Ig constant-region-like domains. The latter domains protrude into the exoplasmic space. It is expressed by the squamous epithelial cells of the female genital tract.

Biochem/physiol Actions
Carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5 OR CEA) is expressed by cancer cells. It is considered as an independent tumor marker in monitoring metastatic colorectal cancer and can be detected in the blood serum. CEA acts as a prognostic marker for malignant diseases (such as early-stage non-small cell lung cancer (NSCLC)). Increase in serum CEA may be attributed to the presence of local inflammation in the lung. CEA level may be a suitable biomarker for predicting tumor response.

Carcinoembryonic antigen (CEA) expression has been shown to protect cancer cell lines from apoptosis and anoikis. The aim of this study was to further elucidate the role of CEA expression on resistance to anticancer drugs in human colorectal cancer (CRC).

Carcinoembryonic antigen (CEA) is a prognostic marker for early-stage non-small cell lung cancer (NSCLC), and cryoablation is a new therapeutic alternative for lung cancer. We determined whether cryoablation-induced changes in serum CEA levels correlated with tumor type (adenocarcinoma or squamous

The serum level of carcinoembryonic antigen (CEA) is a marker of malignant disease but can also be increased in benign diseases. Patients with allergic bronchopulmonary aspergillosis (ABPA) have bronchial asthma showing a wide variety of radiological findings. We measured serum
Oncomarkers play important roles in the detection and management of human malignancies. Carcinoembryonic antigen (CEA, CEACAM5) and epithelial cadherin (E-cadherin) are considered as independent tumor markers in monitoring metastatic colorectal cancer. They are both expressed by cancer cells and can

Infections by Neisseria gonorrhoeae are increasingly common, are often caused by antibiotic-resistant strains, and can result in serious and lasting sequelae, prompting the reemergence of gonococcal disease as a leading global health concern. N. gonorrhoeae is a human-restricted pathogen that
