Abstract:
Objective To observe the expression changes of 12 ischemia-related microRNAs (miRNA) in cerebral ischemia-reperfusion injury after deep hypothermic low flow (DHLF) in mice.Methods A total of 80 3-w eek-old healthy and clean grade C57BL/6 male mice w ere randomly divided into either a DHLF model group or a sham operation group. Each group w as redivided into 4 subgroups according to the time points of 2, 6, 12, and 24 h (10 in each group). The bilateral carotid arteries of the DHLF model group w ere clipped and a DHLF model w as established, w hile the carotid arteries of the sham operation group w ere not clipped. The mice w ere sacrified at each time point and the brain tissue w as removed. The total RNA w as extracted. Quantitative reverse transcriptase polymerase chain reaction w as used to detect miRNA expression. Results Compared w ith the sham operation group, the expression levels of 9 miRNAs w ere upregulated, 2 w ere dow n-regulated, and 1 did not have any significant change in the DHLF model group. Conclusions The expression levels of 11 miRNAs changed significantly after DHLF. It might have a regulatory role in cerebral ischemia-reperfusion injury after DHLF.
