Nature Journal Issues "Expression of Concern" Regarding 2010 Cancer Paper

LONDON - The journal Nature has issued an "Expression of Concern" regarding a 2010 paper due to concerns about the similarity of western blot bands in several figures, according to multiple news sources. The authors of the paper, who no longer have the original data to verify their findings, disagree with the concerns and advise readers to interpret the results cautiously.

The announcement, reported by Nature News, stems from scrutiny of the 2010 paper. The specific nature of the concerns involves the visual similarity of bands presented in western blot figures, a technique used in molecular biology to detect specific proteins. The lack of the original data prevents the authors from independently verifying the accuracy of the images.

This development follows a separate correction published in Nature regarding a 2015 article on the genomic landscape of response to EGFR blockade in colorectal cancer. In Extended Data Fig. 8 of that article, a micrograph was inadvertently duplicated during figure preparation, according to Nature News. The corrected version of the figure, containing the appropriate image, is now available as a supplement.

The authors of the 2010 paper, while disagreeing with the concerns, have acknowledged the limitations imposed by the unavailability of the original data. They have advised readers to approach the findings with caution, as reported by Nature News. The journal's "Expression of Concern" is a formal notice to alert readers to potential issues with the published research.

The situation highlights the importance of data integrity and the challenges that can arise when original research materials are no longer accessible. The journal's action underscores its commitment to maintaining the accuracy and reliability of the scientific record.
