EPHA3 and neoplasm: In the mouse xenograft tumor samples generated by implantation of prostate cancer cells, EphA3 phosphorylation was attenuated and the ERK-ELK signaling and stomatin expression were enhanced in the area where stromal cells infiltrated the tumor.<h4>Conclusion</h4>The EphA-mediated signaling suppresses the ERK-ELK pathway, leading to the reduction of stomatin expression that affects prostate cancer malignancy.
