title: Identification of intelectin overexpression in malignant pleural mesothelioma by serial analysis of gene expression (SAGE).
abstract: Malignant pleural mesothelioma (MPM) is a fatal neoplasm with no acceptable curative approaches. We used serial analysis of gene expression (SAGE) to compare the gene expression pattern of a surgically resected MPM to the autologous normal mesothelium. Intelectin gene overexpression (>139-fold) was found in the tumor. Online SAGE datasets revealed intelectin to be consistently present in mesothelioma(s), ovarian cancer, and colon cancer. Intelectin mRNA expression was found by RT-PCR in 4 of 5 resected MPM tumors, and Intelectin protein expression was confirmed by immunohistochemistry in 28 of 53 MPM tumors, and in 4 of 4 mesothelioma cell lines studied by Western blot. A marked induction in intelectin gene expression was observed among human primary mesothelial cells as a consequence of crocidolite asbestos exposure and simian virus 40 infection. Intelectin overexpression in mesothelioma could have potential screening, and therapeutic implications.
