A Wake-up Call for Research Integrity: Image Duplication Controversy in a Paper from China Pharmaceutical University

In recent years, academic integrity has increasingly become a focal point in the academic community. Publishing in academic journals signifies that research findings will undergo peer review and scrutiny from the scientific community, making it crucial for researchers' reputation and academic advancement. However, a recent incident involving suspected image duplication in a paper by researchers from China Pharmaceutical University has sparked widespread concern within the academic community.

The Incident

• In 2019, Hong-Liang Gao, Yuan-Zheng Xia, Ya-Long Zhang, Lei Yang (corresponding author), and Ling-Yi Kong (corresponding author) from China Pharmaceutical University published a paper titled "Vielanin P enhances the cytotoxicity of doxorubicin via the inhibition of PI3K/Nrf2-stimulated MRP1 expression in MCF-7 and K562 DOX-resistant cell lines" in the renowned pharmaceutical journal Phytomedicine. The paper focused on the sensitization effect of Vielanin P on doxorubicin-resistant cells and explored its underlying molecular mechanisms.

However, in May 2024, several scholars reported concerns about suspected image duplication in the paper on the academic platform Pubpeer. Specifically, they pointed out multiple instances of potential image reuse in the paper, including:

• Figure 2E and Figure 3A: The two GAPDH bands seem remarkably similar, while theoretically, they represent different cell lines and should exhibit differences.

• Figure 3B: The two WB bands appear more similar than expected and show mirror flipping, suggesting potential post-processing.

• Figure 3A and Figure 3C: The WB bands seem to have been cut and reused.

• Figure 3E, Figure 4C, and Figure 4E: The three WB bands appear to be duplicates representing different experimental conditions.

• Figure 4C and Figure 4E: Four sets of WB bands appear to have been reused, representing different experimental conditions.

These allegations have raised questions about the paper's research integrity and sparked widespread discussions within the academic community.

Background of the Researchers Involved

The corresponding author of the paper, Professor Ling-Yi Kong, currently serves as the Vice President of China Pharmaceutical University and holds multiple academic positions. He has extensive research experience in the fields of traditional Chinese medicine chemistry and natural product chemistry. Professor Kong's research focuses on the research and development of new drugs based on traditional Chinese medicine and natural drugs, and he has achieved a series of significant findings.

However, the current image duplication issue will undoubtedly tarnish Professor Kong's academic reputation.

The Impact of Image Duplication

Images in academic papers are an integral part of research findings, providing a visual representation of experimental results and offering important information to readers. However, image duplication or fabrication can severely compromise the authenticity and reliability of academic papers, negatively impacting scientific research progress.

Image duplication not only misleads readers but also affects the academic community negatively, undermining the credibility of academic research. Moreover, image duplication can damage researchers' professional ethics and academic reputation, potentially triggering a crisis of trust in the academic community.

The Academic Community's Stance on Image Duplication

The academic community takes image duplication issues very seriously, considering them as acts of academic misconduct that deserve severe condemnation. In recent years, many academic journals have strengthened their review and scrutiny of images in submitted papers and have implemented stricter preventative measures.

• For instance, top journals like Nature and Science require authors to provide raw experimental data and subject images to careful review. Additionally, some academic institutions have established mechanisms for investigating academic misconduct and handling such cases with seriousness.

Lessons Learned

This incident serves as another wake-up call, reminding us that research integrity is the lifeline of academic research, a fundamental principle that researchers must uphold. Any form of academic misconduct will be condemned and punished by the academic community.

Researchers should strengthen their understanding of ethical guidelines, strictly adhere to academic norms, pursue rigorous scholarship, be honest and trustworthy, and eliminate all forms of academic misconduct. Simultaneously, the academic community should enhance its oversight and disciplinary measures for academic misconduct, fostering a fair and ethical academic environment.

The Aftermath

The follow-up developments in this incident have not been publicly released yet. However, it is predictable that this event will continue to garner attention within the academic community, sparking further discussions concerning research integrity and academic norms.

Further Discussion Points:

• Discuss different types of image duplication and their causes, including human error, improper data processing, and research fabrication.

• Analyze the impact of image duplication incidents on the authors, their institutions, and academic journals.

• Explore how to prevent future occurrences of image duplication, such as strengthening academic integrity education, improving academic integrity systems, and promoting a sense of self-discipline among researchers.

• Summarize the lessons learned from this incident, emphasizing the importance of research integrity, and calling on the academic community to enhance the prevention and governance of academic misconduct.
