タイトル Overexpression of centrosomal protein 55 regulates the proliferation of glioma cell and mediates proliferation promoted by EGFRvIII in glioblastoma U251 cells.
ジャーナル Oncol Lett
Abstract The epidermal growth factor receptor (EGFR) is often amplified in glioma, with the most common extracellular domain mutation being EGFR variant III (EGFRvIII). Abnormal EGFRvIII signaling has been shown to be important in driving tumor progression. Centrosomal protein 55 (CEP55), a member of the centrosomal relative proteins family, participates cytokinesis in the cell cycle. It exists in a few normal tissues and various tumor cells. The expression and function of CEP55 in human glioma cells need to investigate. In this study, the expression of CEP55 was detected in 40 cases of glioma tissues and 10 cases of non-tumor brain tissue. The proliferation of glioblastoma U251 cells was analyzed after transfection with EGFRvIII and CEP55 siRNA. We found that the expression of CEP55 was increased significantly in the glioma tissues than in normal brain tissue. The proliferation of U251 cells increased remarkably after transfection with EGFRvIII. Knockdown of CEP55 inhibited proliferation of U251 cells and was able to eliminate the effect of promoting proliferation induced by EGFRvIII in U251 cells. CEP55 played a key role in the proliferation of glioma cells and mediated EGFRvIII-stimulated proliferation in glioma cells. CEP55 might be a novel molecular therapeutic target in patients with gliomas expressing EGFRvIII.
