miR-21 blockade reverses EMT by regulating CDK5/p35 in HNSCC cells in vitro. a Expression of EMT-related proteins after asON or WP1066 treatment, analyzed by western blot with normalization to β-actin. b Expressions of CDK5 and p35 after asON and WP1066 treatment, determined by western blot with normalization to β-actin. c β-catenin level in nucleus and cytoplasm, analyzed by western blot with normalization to Histone H2A. d Subcellular location of EMT related markers after asON or WP1066 treatment, observed by immunofluorescence staining (original magnification, x100)
