The ephrin and Eph signaling circuit has been reported as deregulated in a number of tumor types including nonsmall cell lung cancer (NSCLC). Here we show that suppression of the ephrin-familly member ephrin B3 decreases NSCLC cell proliferation and has profound effects on cell morphology. To reveal which signaling networks ephrin B3 utilize to regulate(More)
Radiation therapy is frequently used to treat non-small cell lung cancers (NSCLCs). We have previously shown that a combination of ionizing radiation (IR) and the staurosporine analog PKC 412, but not Ro 31-8220, increases cell death in NSCLC cells. To identify genes involved in the enhancement of cell death, a total gene profiling in response to(More)
Ephrin receptors (Ephs) are reported to control metastatic signaling of non-small cell lung cancer (NSCLC) and other tumors. Here we show for the first time that blocking expression of the Eph ligand Ephrin B3 inhibits NSCLC cell migration and invasion. We demonstrate that Ephrin B3 directly binds the EphAs EphA2, EphA3, EphA4, and EphA5. EphA2 Ser897 was(More)
