Background: This observation aimed to investigate the effect of colorectal neoplasia differentially expressed (CRNDE) targeted miR-212-5p on cognitive impairment induced by isoflurane (ISO) anesthesia in rats.
Methods: The cognitive function of rats was measured by Morris water maze test. QRT-PCR detection of CRNDE and miR-212-5p expression levels in rats in each group. Double luciferase was used to verify the targeting relationship between miR-212-5p and CRNDE, and commercial kits were used to detect the level of inflammatory cytokines in hippocampus.
Results: The concentration of CRNDE was enhanced in rats treated by ISO anesthetic. The neurological severity score was elevated, the escape latency of rats was prolonged, the stay time in the quadrant of the platform, and the number of times crossing the platform decreased in the ISO group. The above indexes of rats in ISO + si-CRNDE were improved. MiR-212-5p is a mediator in the management of CRNDE on cognition and inflammation.
Conclusion: CRNDE led to the deterioration of impairment on cognition induced by ISO through suppressing miR-212-5p expression and promoting neuroinflammation.
