Author Correction: We apologize for unintentionally using the wrong figures (Figure 5b and Figure 6e) in the original article. To correct our mistakes, representative images (Figure 5b) and bar graphs (Figure 5d) depicting the migration ability of HepG2 after miR-149-5p inhibitor (100 nM) transfection are provided, and the legends have also been modified accordingly. Representative images (Figure 6e) and bar graphs (Figure 6f) depicting the migration ability of QGY-7703 after siRNA-MTHFR (100 nM) and siRNA-MTHFR NC (100 nM) transfection are also provided. In order to ensure the reliability of the experimental results, we repeated the experiment six times for the new pictures, and this part of the results was included in the Supplementary Materials (Figure S1).

The corrected Figure 5b,d and Figure 6e,f appear below:

In the original publication, the Supplementary Materials was not included. The citation has now been inserted in Section 3.5 Transfection of miR-22-3p/miR-149-5p Inhibitor Promote Migration in HCC Cells In Vitro, Paragraph 1 and should read:

Subsequently, the effects of the miRNA-22-3p/miR-149-5p inhibitor on HCC cell migration were assessed. The transwell assay found that the miR-22-3p/miR-149-5p inhibitor significantly promoted HCC cell migration (Figures 5a–d and S1).

The corrected Supplementary Materials statement appears here. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
