Retraction: Nicotinamide Inhibits Alkylating Agent-Induced Apoptotic Neurodegeneration in the Developing Rat Brain

Abstract

Full text

Following the publication of this article [1], concerns were raised regarding multiple figures, including,

The first author (NU) provided western blot images described as historical data underlying some of the published panels. However, these do not present the full blot area, and no images were provided for loading control panels.

The first author acknowledged that the following panels in this article [1] are incorrect: all panels in Figure 2B; thalamus cytosolic cytochrome-C and β-actin panels in Figure 3; β-actin panels in Figures 4A and 4B; and Figures 5H and K. They provided alternative versions of these panels; however, in the absence of the original data for these figures, the concerns cannot be resolved.

The first author stated that β-actin loading control was analyzed for samples from cortex and thalamus, except in cases where no significant changes in β-actin expression were detected. In the absence of confirmation that a loading control was measured for every sample, the editors remain concerned regarding the reliability of all western blot experiments.

In light of the concerns affecting multiple figure panels that question the reliability of these data, the PLOS ONE Editors retract this article.

NU did not agree with the retraction. HYL, MIN, IU, JWS, and MOK either did not respond directly or could not be reached.

Figures 2B, 3, 4B, 5G, and 5H appear to report material from [2], published in July 2011 by Elsevier, which are not offered under a CC-BY license and are therefore excluded from this article’s [1] license. At the time of retraction, the article [1] was republished to note this exclusion in the legend for Figures 2–5 and the article’s copyright statement.
