The Editor-in-Chief and Publisher of OncoTargets and Therapy have been alerted to unacceptable levels of duplication with another published paper: Zhu D, Chen H, Yang X, Chen W, Wang L, Xu J and Yu L. Decreased microRNA-224 and its clinical significance in non-small cell lung cancer patients. Diagnostic Pathology. 9;198:2014
Accordingly, we retract Zhu D, Chen H, Yang X, Chen W, Wang L, Xu J, Yu L. miR-32 functions as a tumor suppressor and directly targets SOX9 in human non–small cell lung cancer. OncoTargets and Therapy. 2015;8:1773–1783.
