Does interferon-gamma sensitize osteosarcoma cells to Fas-induced apoptosis by up-regulating Fas receptors and caspase-8?
IFN-gamma sensitizes osteosarcoma cells to Fas-induced apoptosis through up-regulation of Fas receptor and caspase-8. Combined immunotherapy with IFN-gamma and either anti-Fas monoclonal antibody or cytotoxic T cells that bear Fas ligand might be a useful adjunctive therapy for patients with osteosarcoma.
PolyADPribosylation from PARP-1 and other sources of enzymatic PAR synthesis is associated with cardiac damage following myocardial ischemia. PARP inhibitors may have therapeutic utility in myocardial disease.
