Expression of Concern

This article refers to:
Ras-PI3K pathway promotes osteosarcoma progression via regulating VRK1-mediated H2A phosphorylation at threonine 120

We, the Publisher and Editor of Artificial Cells, Nanomedicine, and Biotechnology, are issuing an Expression of Concern for the following article: 

Xianlun Xu & Hao Yu (2019) Ras-PI3K pathway promotes osteosarcoma progression via regulating VRK1-mediated H2A phosphorylation at threonine 120. Artificial Cells, Nanomedicine, and Biotechnology, 47(1), 4274–4283, DOI: 10.1080/21691401.2019.1687506

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 provided several files in response to our queries, but they were unable to provide the original data in a format which satisfies our requirements to confirm the authenticity of some types of data. In particular, they were unable to provide full western blots, where the molecular weight markers are indicated. In addition, the authors did not have a record of the full blot, before cutting it into strips.  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.
