PG - 4075-82 AB - L-Type amino acid transporter 1 (LAT1) is known to be highly expressed in various human neoplasms. However, little is known about how LAT1 is expressed in malignant pleural mesothelioma (MPM). Twenty-one patients were included in this study. Tumor sections were stained by immunohistochemistry for LAT1, glucose transporter 1 (GLUT1), GLUT3, hypoxia inducible factor-1alpha (HIF-1alpha), hexokinase I, vascular endothelial growth factor (VEGF), microvessel density (MVD) by determination of CD34, epidermal growth factor receptor (EGFR), phosphatase and tensin analog (PTEN), p-AKT, p-manmalian target of rapamycin (mTOR), p-S6K, p53 and BCL-2. LAT1 was overexpressed in approximately 50% of the patients with MPM. LAT1 expression was closely correlated with CD98, hypoxic markers, the mTOR pathway, Ki-67 and p53. The overexpression of LAT1 was closely associated with poor outcome in patients with MPM. LAT1 is closely associated with tumor development and progression in patients with MPM.
