Submission received: 10 October 2025 / Accepted: 15 October 2025 / Published: 27 October 2025
The journal retracts the article “Protection against Oxidative Stress-Induced Apoptosis by Fermented Sea Tangle (Laminaria japonica Aresch) in Osteoblastic MC3T3-E1 Cells through Activation of Nrf2 Signaling Pathway” [1] cited above.
Following publication, concerns were brought to the attention of the Editorial Office regarding the integrity of images presented in this publication [1].
Adhering to our standard procedure, an investigation was conducted by the Editorial Office and Editorial Board that identified indications of inappropriate editing and image duplication between Figures 4 and 7, presenting different experimental conditions. While the authors collaborated within this process, raw material meeting the journal’s Original Images Requirements could not be provided for Editorial Board Evaluation. Consequently, the Editorial Board has lost confidence in the reliability of the findings and has decided to retract this publication, as per MDPI’s retraction policy (https://www.mdpi.com/ethics#_bookmark30, accessed on 6 August 2025).
This retraction was approved by the Editor-in-Chief of the journal Foods.
The authors did not agree to this retraction.
