In the article titled “MicroRNA-30-3p Suppresses Inflammatory Factor-Induced Endothelial Cell Injury by Targeting TCF21” [1], the authors identified an error introduced during the preparation of the manuscript in Figure 4, where the GAPDH bands were duplicated between Figures 4(d) and 4(h). In Figure 4(d), “ox-LDL + mimics” should also be corrected to “ox-LDL + siRNA.”

Additionally, the significance indicators were omitted from Figures 1, 2, 4, and 5 in error, and in Table 1, a primer was not included. The corrected figures and tables are as below.

Due to an error during manuscript preparation, the incorrect miRNA was stated in the title of the manuscript. The article has been updated from “MicroRNA-30-3p” to “MicroRNA-30-5p” as shown above.

The authors apologize for these errors and confirm that they do not impact the conclusions of the article.
