LAIR-1 overexpression in HOS cells inhibits the expression of EMT-associated transcription factors by decreasing p-Foxo1 expression. a Expression of Twist1 in untreated HOS cells (Blank) and corresponding LV-NC- and LV-LAIR-1-overexpressing transfectants was analyzed by qPCR. b Twist1, N-cadherin, p-Foxo1, total Foxo1, p-Akt, and total Akt expression were analyzed by western blotting in blank, LV-NC-overexpressing, and LV-LAIR-1-overexpressing OS cells. c Twist1, p-Foxo1, and total Foxo1 expression were analyzed by western blotting in blank, negative control (NC) siRNA, and Foxo1 siRNA (siFoxo1)-transfected OS cells. Representative immunofluorescence staining for Twist1 (d) and Foxo1 (e) in HOS cells (left). Cell nuclei were stained with DAPI (blue). Scale bar = 20 μm. The statistical data for the images are shown in histograms (right). *P < 0.05, **P < 0.01. Results represent at least three independent experiments.
