Background
MSLN, also known as Mesothelin, has 4 isoforms, a 630 amino acid isoform that is 69 kDa, a 622 amino acid isoform that is 68 kDa, a 656 amino acid isoform that is 71 kDa, and a 621 amino acid isoform that is 68 kDa, expressed in lung, heart, placenta kidney, and overexpressed in mesotheliomas, ovarian cancers, and some squamous cell carcinomas. Membrane-anchored forms may play a role in cellular adhesion and megakaryocyte-potentiating factor (MPF) potentiates megakaryocyte colony formation in vitro. Current research is being performed on several diseases and disorders including squamous cell carcinoma, ovarian cancer, carcinoma, malignant biphasic mesothelioma, bile duct adenoma, malignant mesothelioma, malignant pleural mesothelioma, gastrointestinal stromal tumor, renal clear cell carcinoma, epithelioid sarcoma, benign mesothelioma, pancreatic ductal adenocarcinoma, asbestosis, pancreatic ductal carcinoma, thymic carcinoma, acute myeloid leukemia, epithelial ovarian cancer, myeloid leukemia, thoracic cancer, and pancreatitis. This protein has also shown an interaction with MUC16 and RSG1 in cell adhesion and pancreas development processes and pathways.
