C16 treatment significantly improved the above signs caused by SAH. By RNA\u2010seq analysis, brain tissue of SAH\u2010treated rats with SAH and C16 differentially expressed mRNA target genes enriched in stress response and organic developmental signaling pathways.<\/jats:p><jats:p><jats:bold>Conclusion<\/jats:bold>: Inhibition of PKR may improve cerebral injury after SAH by inhibiting ferroptosis, and RNA sequencing staged its mechanism of action may
