We, the Editors and Publisher of the journal Cell Cycle, have retracted the following article:
Kun Ma, Chuan Zhang, and Wuyin Li. TGF-β is associated with poor prognosis and promotes osteosarcoma progression via PI3K/Akt pathway activation. Cell Cycle. 2020;19(18):2327-2339. doi: 10.1080/15384101.2020.1805552.
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 address all the concerns raised and have not been able to provide all their original data, or sufficient supporting information. As verifying the validity of published work is core to the integrity of the scholarly record, we are therefore retracting the article. The corresponding author listed in this publication has been informed.
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The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
