Podoplanin/aggrus is increased in tumors and its expression was associated with tumor malignancy. Podoplanin on cancer cells serves as a platelet-aggregating factor, which is associated with the metastatic potential. However, regulators of podoplanin remain to be determined. Transforming growth factor-β (TGF-β) regulates many physiological events, including tumorigenesis. Here, we found that TGF-β induced podoplanin in human fibrosarcoma HT1080 cells and enhanced the platelet-aggregating-ability of HT1080. TGF-β type I receptor inhibitor (SB431542) and short hairpin RNAs for Smad4 inhibited the podoplanin induction by TGF-β. These results suggest that TGF-β is a physiological regulator of podoplanin in tumor cells.
