Abstract
PTPRD is a receptor-type tyrosine-protein phosphatase. Recent analyses of comprehensive mutations and copy numbers have revealed that PTPRD is frequently mutated and homozygously deleted in various types of cancer, including glioblastoma, melanoma, breast and colon cancer. However, the molecular functions of PTPRD in cancer progression have yet to be elucidated. Herein, PTPRD suppressed colon cancer cell migration and was required for appropriate cell-cell adhesion. In addition, PTPRD regulated cell migration in cooperation with β-catenin/TCF signaling and its target CD44. Furthermore, expression levels of PTPRD were down-regulated in highly invasive cancers and were significantly correlated with patient survival. Our findings suggest that PTPRD is required for colon cancer invasion and progression.Entities:
