ABSTRACT
Objective To evaluate the diagnostic value of TSSC1 in glioma patients and its influence on cell biologi-cal behavior of glioma U87 cells. Methods RT-PCR and Western blot were used to examine the expression of TSSC1 in glioma samples, including 80 normal paraneoplastic tissues and 80 primary tumors. MTT and transwell were used to analyze the effect of TSSC1 knockout on proliferation, migration, and invasion in U87 cells. Results TSSC1 is down-regulated in glioma compared to its paraneoplastic counterparts and negatively related to higher grade. Furthermore, knockdown of TSSC1 expression results in increased proliferation, migration and invasion in U87 cells in vitro. Conclusion Our results may worked as a marker for early diagnosis and prognosis of glioma.
