| Summary: | Ischemia/reperfusion (I/R) injury is a common pathological mechanism involved in many ocular diseases. I/R is characterized by microvascular dysfunction and neurodegeneration. However, the mechanisms of neurodegeneration induced by I/R remain largely unknown. This study showed that the expression of long non-coding RNA-CRNDE was significantly upregulated after retinal ischemia-reperfusion (RIR). LncRNA-CRNDE knockdown alleviated retinal neurodegeneration induced by RIR injury, as shown by decreased reactive gliosis and reduced retinal cells loss. Furthermore, lncRNA-CRNDE knockdown directly regulated Müller cell function and indirectly affected RGC function in vitro. In addition, lncRNA-CRNDE knockdown led to a significant reduction in the release of several cytokines after RIR. This study suggests that lncRNA-CRNDE is a promising therapeutic target for RIR.
