EXPRESSION OF CONCERN: ‘Over-expression of long non-coding RNA ZEB2-AS1 may predict poor prognosis and promote the migration,invasion,and epithelial-mesenchymal transition of tumor cells in non-small cell lung cancer’

The Journal Editors and SAGE Publishing hereby issue an expression of concern for the following article: 

Xu H, Yu B, Shen W, Jin C, Wang L, Xi Y. Over-expression of long non-coding RNA ZEB2-AS1 may predict poor prognosis and promote the migration, invasion, and epithelial-mesenchymal transition of tumor cells in non-small cell lung cancer. Int J Biol Markers 2020; 35(3): 29-35. doi:10.1177/1724600820938385

The authors of the article contacted Sage with a request to correct the article due to a conflict of interest.
