We, the Publisher and Editor of Artificial Cells, Nanomedicine, and Biotechnology, are issuing an Expression of Concern for the following article:
Lina Liu, Haoran Zhang, Hongyu Mao, Xiaohong Li & Yamin Hu (2019) Exosomal miR-320d derived from adipose tissue-derived MSCs inhibits apoptosis in cardiomyocytes with atrial fibrillation (AF). Artificial Cells, Nanomedicine, and Biotechnology, 47(1), 3976–3984, DOI: 10.1080/21691401.2019.1671432
After publication of this article, questions about the scientific integrity of the article content were brought to the Publisher and Editor’s attention. We reached out to the authors requesting that they supply information that would confirm the article’s integrity. The authors could not respond in a timely manner to our requests to provide the original data. In particular, they were unable to provide full western blots, where the molecular weight markers are indicated. Therefore, as we continue to work through the issues raised, we advise readers to interpret the information presented in the article with due caution.
The authors have been notified about this Expression of Concern.
