ERBB receptor signaling promotes ependymoma cell proliferation and represents a potential novel therapeutic target for this disease.

Abstract

This study suggests that ERBB receptor signaling results in aggressive disease behavior in ependymoma by promoting tumor cell proliferation. An analysis of ERBB2 and ERBB4 expression, in association with Ki-67 LI and the degree of surgical resection, may provide an accurate tool for assessing disease risk in children with this disease. In addition, these receptors may serve as a target for novel therapeutic approaches in ependymoma.
