The degeneration of retinal ganglion cells (RGCs) has been identified as a major problem in glaucoma. Previous studies have indicated an association between annexin Al (ANXA1) and neuronal cell apoptosis, and RGCs apoptosis in acute ischemia-reperfusion was attributed to an increased production of IL-1 beta. We found that the expression and nuclear translocation of ANXA1 were upregulated in models of acute ischemia-reperfusion in RGCs in vivo. ANXA1 was found to have a promoting effect on the expression of IL-1 beta in primary cultured RGCs, which could be inhibited by treatment with ANXA1 shRNA or the p65 inhibitor BAY 11-7082. ANXA1 interacted with p65, and recruited it into the nucleus. Chromatin immunoprecipitation assay revealed that ANXA1 accumulated at the IL-1 beta gene promoter. The reduction of p65 nuclear translocation using a membrane permeable ANXA1 peptide containing a Ser5Ala mutation led to a decrease in the expression of IL-15, and acute ischemia-reperfusion induced RGCs apoptosis in vivo. These results indicate that in RGCs, ANXA1 increases IL-1 expression by recruiting p65 to the nucleus, which induces cell apoptosis. The obtained results may help the development of a novel treatment strategy against RGCs apoptosis in acute ischemia-reperfilsion injury.
