Background:

The MSLN gene encodes a 69 kDa precursor protein that is proteolytically cleaved to yield Megakaryocyte Potentiating Factor (MPF) and a GPI-anchored membrane protein termed mesothelin . Expression of (cleaved) mesothelin is largely confined to mesothelial cells of normal pleura, pericardium, and peritoneum, but has been reported to be overexpressed in some cancers, including mesothelioma, and some pancreatic and ovarian adenocarcinomas (1,2). Although suggested to be involved in cell adhesion, the physiological functions of mesothelin have not been determined. It is known, however, that mesothelin can be shed from the cell surface following cleavage by TNF-α converting enzyme. Research studies show that serum levels of mesothelin are markedly increased in patients with mesothelioma and ovarian cancer , suggesting that serum mesothelin levels may have utility as a cancer biomarker (1-3).
