Correction: Oleanolic Acid Inhibits Epithelial–Mesenchymal Transition of Hepatocellular Carcinoma by Promoting iNOS Dimerization

In the original version of this article (1), the OA + Reg group image was incorrectly used in the representative image of the OA group in Fig. 5C. Also, in Fig. 5F, the representative image for the OA+Reg group (NT IHC) was incorrectly used as the OA group (NT IHC). The statistical data of this experiment were not affected. The authors apologize for the oversight, and the online version of the article has been updated with the corrected Fig. 5C and F.
