Expression of Y-box binding protein-1 (YB-1) is associated with tumor progression and drug resistance. Phosphorylation of YB-1 at serine residue 102 (S102) in response to growth factors is required for its transcriptional activity and is thought to be regulated by cytoplasmic signaling phosphatidylinositol 3-kinase (PI3K)/Akt and mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathways. These pathways can be activated by growth factors and by exposure to ionizing radiation (IR). So far, however, no studies have been conducted on IR-induced YB-1 phosphorylation.

Precise proton irradiation of the cardiac apex using the SARRP
In this video of the Spotlight series, Dr. Verginadis shares about his experience using the SARRP, specifically with proton irradiation of the cardiac apex. Dr. Verginadis works with the SARRP at the UPenn Department of Radiation Oncology, studying a variety of topics...
