Abstract
To investigate the effect of moesin expression on cell proliferaton and invasion of human glioblastoma cell lines in vitro. Glioblastoma LN229 and U87 cells were transfected with the H4645-plenti-EGFP-moesin expression vector for moesin up-regulation. Moesin and β-catenin expression levels in the transfected cells were analyzed by real-time polymerase chain reaction (PCR) and Western blotting. Cell proliferation was measured using the CCK8 assay. Cell invasion and migration ability were assessed using a transwell cell invasion and wound-healing assay. Moesin mRNA and protein expression were significantly increased in the two transfected LN229-H4645 and U87-H4645 cell lines. β-catenin expression was increased by moesin up-regulation in the transfected LN229-H4645 and U87-H4645 cell lines. The CCK-8 assay revealed that up-regulating moesin results in a significant increase in glioblastoma cell proliferation. Glioblastoma cell invasion and migration were increased by moesin up-regulation. Up-regulation of moesin expression in glioblastoma cells correlated with increases in cell proliferation, invasion and migration, suggesting moesin's role in glioblastoma progression.
