Using the SG-specific marker G3BP1, we tested whether platinum-based drugs such as CisPt, oxaliplatin (OxaPt) and carboplatin (CrbPt) also stimulate formation of G3BP1-positive cytoplasmatic foci as sodium arsenite (SA) and vinorelbine (VRB) in human osteosarcoma U2OS cells (Fig. 1A). Here, G3BP1 is linked to osteosarcoma.
