“…Employing cytology, immunohistochemistry, and polymerase chain reaction analyses, we have previously reported that heparanase is expressed by mesothelioma patients (25,26). Likewise, human (CD484 [not shown], CD487, MSTO-211H, and NCI-H2052) and mouse (AE17, AK7, RN5) pleural mesothelioma cell lines exhibit typical high levels of heparanase activity (Supplementary Figure 1A, available online).…”
