m6A RNA methylation profiling in hippocampus of POCD mice induced by sevoflurane
Elderly patients are apt to cognitive impairment and memory loss after surgical operations. This perioperative cerebral damage named postoperative cognitive dysfunction (POCD) is profoundly affected by anesthesia. N6-methyladenosine (m6A) RNA methylation as a widely-studied epigenetic modification to regulate gene expression, however, is never studied in POCD. Initially, fifty 40-week-old outbred female C57BL/6 mice were conducted Morris water maze test by EthoVision XT working system (Noldus, Netherlands) as manufacturer's instructions. The escaping latent period of each mouse were recorded. Then Thirty mice were randomly selected and given 2% sevoflurane for 4 h in an automatic anesthetic chamber with size of 24 cm*12 cm*18 cm. After natural resuscitation, POCD and non-POCD mice were picked up based on the dynamics of escaping latent period. The other twenty mice received normal air were treated as negative control. Hippocampus were conducted RIP-seq for investigating m6A RNA methylation.
