RETRACTED: Protein Kinase D1 Is Increased in Tumor Tissue,Correlates With Advanced Tumor Features and Worse Prognosis of Non-Small Cell Lung Cancer

This retraction notice supersedes the previously published Expression of Concern (https://doi.org/10.1177/15330338231184684).

Sage was made aware of a conversation on PubPeer discussing this article (PubPeer - Protein Kinase D1 Is Increased…).

The concerns are summarized as follows:

The article shares several characteristics with 17 other published articles from different hospitals and linking specific proteins or RNA to survival rates.

After an internal investigation Sage has become aware that the article contains indicators of third-party involvement.

The authors were contacted multiple times by Sage about these issues, but no response was received.

Due to concerns around author contributions to this article, as well as concerns around the integrity of the research process, Sage and the Journal Editor retract this article.
