INTRODUCTION
CEA, whose gene family consists of approximately 30 genes, is a glycoprotein
expressed in the embryonic tissue as well as several malignant neoplasms including
colorectal carcinoma. It has been shown to be associated with cellular differentiation and
tumor invasion. The functional role of CEA in the tumor biology can be summarized
into two different pathways, e.g., modulation of immune responses and facilitation of
intercellular adhesion. Adhesive function of CEA between cells or cells and extracellular
matrix proteins is known to affect cellular invasion and metastasis in colorectal
carcinoma.
The pattern of adhesion between glycophosphatidyl inositol-linked CEA and
transmembrane-linked biliary glycoprotein (BGP) varies depending on the temperature of
environment and mediating divalent cation. Although CEA-mediated adhesion obviates
strict condition of temperature or divalent cation, a stable structure of CEA molecule is
indispensable. CEA including its other family members consists of four domains: a
leader peptide, an N-terminal domain, a variable number of repeating loop domain, and a
short C-terminal domain.
CEA-mediated adhesion has recently been shown to involve two domains by double
reciprocal bonds. Since all bonds share N-terminal domain as a binding site, truncation
or deletion in this domain can be expected to affect the stable homophilic binding. The
present study was aimed at verifying the conservation of N-terminal domain exons.
Since the distribution of CEA is ubiquitous and no longer to be considered as an
oncofetal molecule, genomic DNA from lymphocytes rather than tumor tissue of colon
cancer patients was tested.
