Epithelial cell biomolecules

Epithelial cell biomolecules is a generic term encompassing a diverse array of molecules found within or on the surface of epithelial cells, which constitute the lining of various organs and structures in the body (StatPearls: Epithelium, 2023). This category includes structural proteins like cytokeratins, adhesion molecules such as E-cadherin (CDH1) and EpCAM, and various receptors involved in cell signaling (NCBI Gene: CDH1, 2024; NCBI Gene: EPCAM, 2024). Because this term describes a broad class of biological components rather than a single, specific protein or receptor, it is not considered a valid therapeutic target for drug development. While specific molecules within this group are frequently targeted in the treatment of carcinomas and inflammatory conditions, the collective term lacks the specificity required for pharmacological intervention. Consequently, drug discovery efforts focus on individual, well-characterized members of this group rather than the category as a whole.
