In a separate study in 2023, Hu et al., 2023 demonstrated that CDGSH iron-sulfur domain 2 (CISD2) was upregulated and activated the Nrf2/HO-1 signaling pathway in both the MCAO mouse model and the OGD/R HT22 cell model, mimicking in vivo and ex vivo conditions of cerebral ischemia and reperfusion. This evidence concerns the gene CISD2 and Cerebral ischemia.
