PURPOSE Constitutively activated signal transducer and activator of transcription 3 (STAT3) and ErbB2 are involved in the pathogenesis of many tumors, including astrocytoma. Inactivation of these molecules is reported to result in radiosensitization. The purpose of this study was to investigate whether inhibition of STAT3, ErbB2, or both could enhance(More)
Thrombopoietin (TPO) can regulate hematopoiesis and megakaryopoiesis via activation of its receptor, c-Mpl, and multiple downstream signal transduction pathways. Using the cytoplasmic domain of Mpl as bait, we performed yeast two-hybrid screening, and found that the protein Atp5d might associate with Mpl. Atp5d is known as the δ subunit of mitochondrial ATP(More)
