Transmembrane protease serine 3 (TMPRSS3) is a member of type II transmembrane serine proteases (TTSP) family, which play important roles in the development and progression of various cancers. However, the role of TMPRSS3 in glioma remains unclear. In the present study, we evaluated the expression patterns of TMPRSS3 in clinical tumor samples and glioma cell lines. The results showed that TMPRSS3 was highly expressed in both human glioma tissues and cell lines. Knockdown of TMPRSS3 in glioma cells by transfection with small interfering RNA targeting TMPRSS3 (si‐TMPRSS3) significantly suppressed cell proliferation and migration/invasion. Moreover, knockdown of TMPRSS3 markedly elevated the apoptotic rate of glioma cells. Si‐TMPRSS3 transfection also resulted in a remarkable increase in bax expression and a notable decrease in bcl‐2 expression in glioma cells. Furthermore, TMPRSS3 knockdown markedly suppressed the expressions of Notch1 and Hes1. The results indicated that knockdown of TMPRSS3 exhibited antiglioma effect, which is associated with the inactivation of the Notch signaling pathway. These findings suggested that TMPRSS3 might be used as a therapeutic target for glioma treatment.
