Abstract
Zhang, X., Lu, Y., Wu, Q., Dai, H., Li, W., Lv, S., Zhou, X., Zhang, X., Hang, C. and Wang, J. (2019). Astaxanthin mitigates subarachnoid hemorrhage injury primarily by increasing sirtuin 1 and inhibiting the Toll-like receptor 4 signaling pathway.

The original paper of this article contains an error in Figure 6K for the SAH + vehicle (KO) group. The corrected Figure 6 is presented below. The mistake does not change the results or conclusions of the study. The authors apologize for the error.
FIGURE 6. Effects of ATX on neuronal death, brain edema, and neurologic function at 24-h post-SAH. ATX (0.1 mM) was administered to rats via intracerebroventricular injection at 30 min after SAH. (A) Western blot analysis for Bcl2, Bax, and caspase-3. (B) Quantification of Western blots showed that ATX significantly decreased levels of cleaved caspase-3 and Bax, and enhanced levels of Bcl2. (C, D) Representative photomicrographs of immunofluorescence staining for caspase-3 and TUNEL staining in the indicated experimental groups. (E, F) Quantification showed that SAH rats treated with ATX had significantly fewer caspase-3–positive and TUNEL-positive neurons than did the vehicle-treated SAH group. *p < .05, n = 6/group.

期刊介绍：
The FASEB Journal publishes international, transdisciplinary research covering all fields of biology at every level of organization: atomic, molecular, cell, tissue, organ, organismic and population. While the journal strives to include research that cuts across the biological sciences, it also considers submissions that lie within one field, but may have implications for other fields as well. The journal seeks to publish basic and translational research, but also welcomes reports of pre-clinical and early clinical research. In addition to research, review, and hypothesis submissions, The FASEB Journal also seeks perspectives, commentaries, book reviews, and similar content related to the life sciences in its Up Front section.
