The interactions of tumor cells with platelets contribute to the progression of tumor malignancy, and the expression levels of platelet aggregation-inducing factors positively correlate with the metastatic potential of osteosarcoma cells. However, it is unclear how tumor-platelet interaction contributes to the proliferation of osteosarcomas. We report here that osteosarcoma-platelet interaction...
32D cells transfected with the human alpha platelet-derived growth factor receptor (alpha PDGFR) bind PDGF-AA, -AB, and -BB isoforms with high affinity, and the binding of each can be efficiently competed by all three isoforms. In an effort to develop better understanding of spatial relationships of binding sites for PDGF-AA and -BB, we constructed an alpha PDGFR mutant which deleted amino acid...
Self-amplification of phosphoinositide 3-kinase (PI3K) signaling is believed to regulate asymmetric membrane extension and cell migration, but the molecular organization of the underlying feedback circuit is elusive. Here we use an inducible approach to synthetically activate PI3K and interrogate the feedback circuitry governing self-enhancement of 3'-phosphoinositide (3-PI) signals in NIH3T3 f...
