Correction: Inhibitor of Apoptosis-Stimulating Protein of p53 (iASPP) Is Required for Neuronal Survival after Axonal Injury

Abstract

Figures

Full text

After publication of this article [1], concerns were raised regarding Figs 1-3 and 6. Specifically:

The corresponding author, ADP, stated that in Figs 1A, 2A and 3A, the same representative photomicrograph of an intact/uninjured retina was intentionally used across multiple figs to illustrate baseline retinal morphology. They also stated that Fig 3C is incorrect and Fig 2C is correct. The Fig 3C immunohistochemistry panel has been replaced with the correct image from the original dataset in the updated Fig 3 in S1 File. Underlying data in support of Figs 1-3 are provided here in S2-S3 and S5-S6 Files.

The corresponding author stated that the β-actin blot in Fig 6A is incorrect, and the β-actin blot in Fig 3G is correct. The β-actin panel in Fig 6A has been replaced with the correct loading control derived from the original experiment in the updated Fig 6 provided here. The corresponding author also stated that they were unable to locate the original uncropped western blots for Fig 3G, and the specific PUMA western blot image originally used to assemble Fig 6D. They have therefore provided uncropped western blots from parallel experiments conducted at the same time as the original experiments and used in the original quantitative analyses for Figs 3G and 6D in S3-S4 Files. Fig 6D has been replaced with these alternative blots generated at the time of the initial experiments in the updated Fig 6 provided here. Underlying data in support of the updated Fig 6 are provided here in S4 and S6 Files.

The corresponding author stated that the remainder of the underlying data supporting [1] are available upon request, with the exception of the individual-level quantitative data for the intact iASPP siRNA-treated retinal ganglion cell counts in Fig 3I, a non-injured control group.
