ICAM-1 also known as CD54 is a protein that in humans is encoded by the ICAM1 gene. ICAM-1 is an important regulator of cell–cell interactions and recent studies have shown that it promotes malignancy in several carcinomas.
Intercellular Adhesion Molecule 1 (ICAM-1) is a cell surface glycoprotein that plays a critical role in the immune response by facilitating the adhesion of leukocytes to endothelial cells. It is part of the immunoglobulin superfamily and is involved in various cellular processes, including inflammation, immune response, and tumor progression.
Expression in Cancers: ICAM-1 is often overexpressed in various types of cancers, including breast, lung, colorectal, and melanoma. Its expression can be induced by pro-inflammatory cytokines, growth factors, and other stimuli present in the tumor microenvironment.
Prognostic Implications: The expression levels of ICAM-1 have been associated with cancer prognosis. In some studies, high levels of ICAM-1 expression correlate with poor prognosis, increased tumor aggressiveness, and a higher likelihood of metastasis.
