The University of Wyoming has recommended the retraction of the article by Xu et al. [1] because of evidence of reuse of images in Duan et al. [2], and Xu et al. [3] that significantly affect the results and conclusions reported in this paper [1]. The images for the control and oxLDL (oxidized low-density lipoprotein) exposure in Figure 1 from Xu et al. [1] are similar to those labelled as exposure to NAC (N-acetyl cysteine) in Figure 2 [2] and Figure 1a [3], and exposure to oxLDL + α-ZAL (α-Zearalanol) [3], respectively. The article [1] has been retracted.
