It was reported that in a neonatal rat model of cerebral ischemia and hypoxia, miR‐210 induces the polarization of microglia toward the M1 phenotype partly by targeting SIRT1, which reduces the deacetylation of the NF‐κB subunit p65 and increases NF‐κB signaling (Li et al., 2020). The gene discussed is NFKB1; the disease is brain ischemia.
