RETRACTED: TRIM21 deficiency confers protection from OGD/R-induced oxidative and inflammatory damage in cultured hippocampal neurons through regulation of the Keap1/Nrf2 pathway

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). The authors have requested that this paper be retracted as they were unable to repeat some results reported in this paper under the same conditions. In Figure 1D, they found that TRIM21 siRNA-1 could not silence the expression of TIRM21. Therefore, the subsequent results were no longer reliable. The authors apologize for any inconvenience this retraction may cause for readers.
