Aberrant L1 Cell Adhesion Molecule Expression in Cancer: In View of Proliferation, Migration and Invasion / 대한갑상선학회지

ABSTRACT

L1 cell adhesion molecule (L1CAM) is a 220-kDa type I membrane glycoprotein and is normally expressed in neuronal cells, endothelial cells, and renal epithelial cells. Recent clinical studies demonstrated aberrant L1CAM expression in various cancers, especially at the invasive area of cancers. L1CAM has a key role in tumorigenesis, tumor invasion, and it is associated with a poor prognosis of cancer. Anaplastic thyroid carcinoma (ATC) has a highly poor outcome and it is resistant to conventional treatment. In this review, I discuss the biological role of L1CAM in proliferation, migration, and invasion in the ATC.
