In this article [1], the wrong figure appeared as Fig. 7a; the Fig. 7 should have appeared as shown below and the sentence needs to be revised in the “Functional analysis of the Result section” should be:

The sentence currently reads:


Further PPI analysis of MKRN3 illustrated that there were 31 nodes based on a combined score ≥ 0.7 in the STRING analysis, and that P53 might be a direct target gene of MKRN3 (Fig. 7a).

The sentence should read:


Further PPI analysis of MKRN3 illustrated that there were 31 nodes based on a combined score ≥ 0.15 in the STRING analysis, and that P53 might be a direct target gene of MKRN3 (Fig. 7a).

P53 might be a target gene of MKRN3. a STRING analysis in the protein–protein interaction of MKRN3. Only the proteins with more than one interaction are displayed. b The homologous modeling and molecular docking with MKRN3 and P53. Red and blue cartoon represent MKRN3 and P53, respectively. The rectangle highlights the interacted domain. c Relative expression of P53 protein in Tcal1183 and JHU011 cells that transfected with MKRN3 cDNA and normalized for GAPDH
