Abstract
The following article has been retracted as a result of our determining the likelihood of manipulation of the peer-review process:
“Lupeol Induces Apoptosis and Cell Cycle Arrest of Human Osteosarcoma Cells Through PI3K/AKT/mTOR Pathway,” by Yan Liu, MD, Tingting Bi, MD, Wei Dai, PhD, Gang Wang, PhD, Liqiang Qian, MD, Genhai Shen, MD, and Quangen Gao, MD, Technology in Cancer Research & Treatment, DOI: 10.1177/1533034615609014
After investigating the peer-review process for the article, SAGE determined that the peer-review process was likely compromised. Our review identified an unusual verbatim repetition of review comments provided from different peer-reviewer accounts provided by submitting author, Quangen Gao, MD, as recommended reviewers. SAGE apologizes to readers and regrets that the academic record has been compromised as a result of this manipulation of the peer-review process.
