This Retraction follows an Expression of Concern relating to this article previously published by Portland Press. This article is being retracted from Bioscience Reports at the request of the authors following receipt of a notification from a reader, alerting the Editorial Office to two regions of the figure 6b MI/R + Dex + EX527 panel that also appear in another paper by different authors (“Protective effect of tanshinone IIA against cardiac hypertrophy in spontaneously hypertensive rats through inhibiting the Cys-C/Wnt signaling pathway” (Feng et al 2017) doi: 10.18632/oncotarget.14328). The Editorial Office also has concerns regarding the western blot images. The authors wish to retract the article, and the Editor-in-Chief and Editorial Board agree with the retraction.
