# EXPRESSION OF CONCERN: Subtype‐Specific Alterations of the Wnt Signaling Pathway in Breast Cancer: Clinical and Prognostic Significance

## TL;DR

This paper addresses concerns about data integrity in a 2012 study on Wnt signaling in breast cancer, leading to an official Expression of Concern.

## Contribution

The paper formally acknowledges unresolved concerns about data authenticity in a prior study on Wnt pathway alterations in breast cancer subtypes.

## Key findings

- Concerns were raised about the integrity of data in Figure 2b of the original study.
- The authors could not provide original data for verification due to the passage of time.
- The journal issued an Expression of Concern due to unresolved data authenticity issues.

## Abstract

EXPRESSION OF CONCERN: N. Mukherjee, N. Bhattacharya, N. Alam, A. Roy, S. Roychoudhury, and C.K. Panda, “Subtype‐Specific Alterations of the Wnt Signaling Pathway in Breast Cancer: Clinical and Prognostic Significance,” Cancer Science 103, no. 2 (2012): 210–220, https://doi.org/10.1111/j.1349‐7006.2011.02131.x.

This Expression of Concern is for the above article, published online on 25 October 2011, in Wiley Online Library (wileyonlinelibrary.com), and has been issued by agreement between the journal Editor‐in‐Chief, Masanori Hatakeyama; the Japanese Cancer Association; and John Wiley & Sons Australia Ltd. The Expression of Concern has been agreed due to concerns raised by a third party after publication regarding the similarity of certain bands in Figure 2b and the underlying data that they represent. The authors could not provide the original data given the time that had elapsed since publication. Because the publisher was not able to examine the original data, it was not possible to investigate fully the concerns raised. Therefore, the journal is issuing this Expression of Concern because the concerns regarding the integrity of the data and the results presented cannot be resolved. Chinmay K. Panda agrees with this decision on behalf of the authors.
