hnRNP K increased stress fibers of microtubule through MAP 1B-LC1 and was associated with the acetylation of ɑ-tubulin. a Immunofluorescent analysis for the formation of stress fibers. hnRNP K (red), tubulin (green), and DAPI (blue) staining were shown, respectively. b Western blotting analysis of the expression of acetylated-ɑ-tubulin. A549 cells stably overexpressing hnRNP K or vector were transfected with NC siRNA or hnRNP K siRNA, and then stimulated with 5 ng/mL TGF-β1. c Quantifications of the expression of acetylated-ɑ-tubulin. Mean ± standard deviation (error bars) of three separate experiments performed in triplicate. ^*P < 0.05
