Taken together, our data suggest that ephrin-B2-dependent EphB4 phosphorylation acts as an anchoring signal to reduce the malignancy by inhibiting Akt phosphorylation in the glioma core, whereas the scarcity of signaling in the tumor periphery promotes invasion into the surrounding brain.
There was a statistically significant correlation between EFNB2 expression and number of lymph node metastasis (P<0.05), and a trend toward statistical significance for correlation between EFNB2 expression and American Joint Committee on Cancer Classification Stage (P<0.1), indicating that EFNB2 expression was up-regulated by advancement of the disease process.
