Fig. 6From: Identified IGSF9 association with prognosis and hypoxia in nasopharyngeal carcinoma by bioinformatics analysisIn vitro functional analysis of IGSF9. a CNE2 and 5-8F cells were transfected with siIGSF9#1 and siIGSF9#2 and subjected to western blotting for IGSF9. b Proliferative potential of two cell lines with interference of two siRNAs were analyzed by CCK8 assay. c, d NPC cells were treated with siRNA (siIGSF9#1) and subjected to transwell assay (c) and wound healing assay (d). e, f qRT-PCR (e) and western blotting (f) in CNE2 and 5-8F cells cultured under normoxia or hypoxia. All data are displayed as mean ± SD, *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
