摘要
Glioblastoma is one of the most common primary nervous system tumors and has a high mortality rate. It is necessary to explore a novel biological target and treatment approach. Twisted gastrulation signaling modulator 1 (TWSG1) is expressed in many tumors and closely related to tumor growth and proliferation. However, there is almost no report about the mechanism of TWSG1 in glioma. We used a glioma chip to detect the expression level of TWSG1 by Immunohistochemistry. The overexpression and silence experiments of TWSG1 were performed to assay the biological function of TWSG1 in LN229 and U251 cells. Subcutaneous xenograft mouse model presented the effect of TWSG1 expression on the malignant behavior of tumor cells. Experimental results displayed that the expression level for TWSG1 was substantially elevated in gliomas compared to that in normal brain tissue. The expression knockdown of TWSG1 caused inhibition of glioma cell proliferation. Besides, TWSG1 overexpression enhanced proliferation in glioma cells, and the capacity of proliferation was partly abolished by the PI3K inhibitor LY294002. We found that TWSG1 affected the activity of Akt signaling pathway. In conclusion, TWSG1 is overexpressed in glioma tissue and promotes tumor proliferation through Akt signaling pathway, may serve as a potential target for glioma diagnosis and therapy.
