Title: TM4SF1 promotes glioma malignancy through multiple mechanisms
Author: Yan-Wen Zheng, Man Wang, Zhao-Min Zhong, Guo-Qing Wu, Ting Zhang, Li-Li Chen, Ming Li

Abstract: Transmembrane-4 L Six Family member 1 (TM4SF1) belongs to a family of integral membrane proteins implicated in cell growth and tumor progression. Glioma is the most common and aggressive malignant brain tumor in adults. In this study, we showed that TM4SF1 was highly expressed in glioma tumor tissues and cell lines. The expression levels of TM4SF1 were negatively correlated with patients’ survival rates. Silencing TM4SF1 by RNA interference inhibited the proliferation, migration, and invasion of glioma cells. Moreover, TM4SF1 silencing induced glioma cell cycle arrest and early apoptosis. In contrast, overexpression of TM4SF1 in glioma cells exhibited the opposite effects. Mechanistically, we found that loss of TM4SF1 reduced phospho-ATK, Cyclin D1, Bcl-2, and MMP9 levels in glioma cells. Taken together, these findings provide novel insights into glioma pathogenesis and suggest that TM4SF1 may represent a novel target for glioma intervention.
