    Platelet-Derived Lysophosphatidic Acid Mediated LPAR1 Activation as a Therapeutic Target for Osteosarcoma Metastasis

    Investigators identified that osteosarcoma cells commonly exhibited high platelet activation-inducing characteristics, and molecules released from activated platelets promoted the invasiveness of osteosarcoma cells.

    Blocking the GITR-GITRL Pathway to Overcome Resistance to Therapy in Sarcomatoid Malignant Pleural Mesothelioma

    Researchers investigated the role of the GITR-GITRL pathway in mediating the resistance to therapy. They found that GITR and GITRL expressions were higher in the sarcomatoid cell line than in non-sarcomatoid cell lines.
