Neuroscience letters 2021 Apr 17Molecule's mechanism of action interacting with CasL 1 (MICAL1) in spinal cord injury (SCI) is unclear. This study aimed to detect the function of MICAL1 in SCI. Western blot was used to analyze the change of MICAL1 in vivo. Immunofluorescence staining was used to detect the location of MICAL1 expression. Oligodendrocyte cells were treated with H2O2 to induce oxidative injury. Subsequently, siRNA transfection was performed to decrease MICAL1 expression in oligodendrocyte cells. Then, the effects of MICAL1 on oxidative stress, apoptosis, and autophagy were assessed. We found that silencing of MICAL1 could significantly reduce the levels of the nuclear factor erythroid 2-related factor 2 (Nrf2), increase the expression of pro-apoptotic factors (Bax and C-caspase 3), decrease the levels of anti-apoptotic factor (Bcl-2) and pro-autophagy factors (Beclin1 and LC3B). Therefore, MICAL1 is a potential target gene for SCI clinical therapy. Copyright © 2021. Published by Elsevier B.V.
