We, the Editors and Publisher of the journal Artificial Cells, Nanomedicine, and Biotechnology, have retracted the following article:
Dongtao Li, Yan Liu, Rong Xu, Xin Jia, Xing Li, Cong Huo & Xiaoming Wang (2019) Astragalus polysaccharide alleviates H2O2-triggered oxidative injury in human umbilical vein endothelial cells via promoting KLF2, Artificial Cells, Nanomedicine, and Biotechnology, 47:1, 2188-2195, DOI: 10.1080/21691401.2019.1621886
Since publication, concerns have been raised about the integrity of the data in the article. When approached for an explanation, the authors have been unable to verify their original data, and therefore have agreed to retract the article.
We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
