چکیده انگلیسی
Glioblastoma (GBM), the most common primary brain tumor, is the leading cause of deaths related to tumors in the central nervous system. The prognosis of GBM patients is currently poor, and the mechanisms underlying GBM genesis remain unclear. The expression of MUC4, a high-molecular-weight and highly glycosylated protein, has been studied in many cancers. However, information on MUC4 expression in GBM is limited. In this study, we found that MUC4 was overexpressed in GBM cell lines and tissues. The proliferation and invasive potential of GBM cells were significantly increased by the ectopic expression of MUC4. By contrast, RNA interference targeting MUC4 in GBM cells significantly decreased the proliferation and invasive potential of GBM cells. We also found that the expression of epidermal growth factor receptor (EGFR) was modulated by MUC4. EGFR inhibition by siRNA reversed the MUC4-induced proliferation and invasion. These results indicated that MUC4 expression in GBM was important in GBM cell proliferation and invasion, which may be partly associated with EGFR overexpression.
