Scientific Reports Retracted Prostate Cancer Study
Editors pulled a 2026 paper after discovering unexplained irregularities in multiple figures within the text.
Updated on Sept. 23, 2026 in Cancer
Scientific Reports has formally retracted a research paper focused on the protein PTEN and its role in prostate cancer treatment. The journal took the action after authors failed to address concerns regarding duplicated images and other data inconsistencies.
Why it matters
The retraction aims to maintain the integrity of medical research after findings were compromised by suspected data duplication. The journal editors stated they no longer have confidence in the study results or the conclusions drawn by the research team.
The investigation identified irregularities across 6 specific figures, including Figures 1B, 4A, 4F, 6A-B, and S3. The primary concern involved the duplication of a PTEN blot in Figure 1B from an unrelated prior publication.
The players
Scientific Reports
This peer-reviewed, open-access scientific journal is published by Nature Portfolio and covers research from all areas of the natural and clinical sciences.
The details
The paper, titled 'Loss of PTEN-assisted G2/M checkpoint impedes homologous recombination repair and enhances radio-curability and PARP inhibitor treatment response in prostate cancer', faced scrutiny when editors compared its data to existing literature. Investigators found the PTEN blot matched a CtIP expression blot from a separate, older study.
Timeline
September 23, 2026: The formal retraction notice was published by Scientific Reports.
The Big Picture
The journal's decision follows the established transparency protocols mandated by the Committee on Publication Ethics guidelines for handling research misconduct.
This retraction clarifies that the findings in the paper regarding PTEN and PARP inhibitors cannot be used to guide clinical treatment decisions. Patients and medical providers should disregard these specific study conclusions when evaluating prostate cancer therapy options.
The takeaway
Reliable medical research depends on the transparent presentation and verification of underlying data. When studies are retracted, it serves as a necessary corrective measure to protect the scientific community and improve the accuracy of future cancer research.
