RETRACTION: Notch1 Protects Against Myocardial Ischaemia-Reperfusion Injury via Regulating Mitochondrial Fusion and
Insights
This study on Notch1 and myocardial ischemia-reperfusion injury is retracted due to duplicated figures and unreliable data. The authors voluntarily requested retraction after concerns were raised.
Area of Science:
- Cardiovascular Research
- Molecular Medicine
- Cellular Biology
Background:
- Myocardial ischemia-reperfusion (I/R) injury is a significant clinical challenge.
- The role of Notch1 signaling in cardiac protection requires further elucidation.
Purpose of the Study:
- To investigate the protective effects of Notch1 against myocardial I/R injury.
- To explore the underlying mechanisms involving mitochondrial dynamics.
Main Methods:
- The study utilized experimental models to assess myocardial I/R injury.
- Mitochondrial fusion and function were evaluated using specific assays.
Main Results:
- The original study suggested Notch1 activation conferred protection against myocardial I/R injury.
- Proposed mechanisms involved the regulation of mitochondrial fusion and improved mitochondrial function.
Conclusions:
- The retracted study concluded that Notch1 plays a protective role in myocardial I/R injury.
- Concerns regarding data integrity, specifically duplicated figures, led to the retraction.

The above article, published online on 23 January 2020 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor-in-Chief, Stefan N. Constantinescu; the Foundation for Cellular and Molecular Medicine; and John Wiley & Sons Ltd. The retraction has been agreed upon following concerns raised by a third party. An investigation determined that Figures 4C, 4D, and elements of Figure 6B, duplicate figures previously published in other articles by a different author group. Due to errors in image management leading to unreliable data, the authors have voluntarily requested retraction. The editors consider the results and conclusions compromised.
