2.11 RT-qPCR
​Total RNA was extracted from the cerebral cortex on the injured side using RNA extraction reagents (Thermo Fisher, cat. no. 12183016). The concentration and purity of the RNA were measured, and the cDNA synthesized by reverse transcription was amplified using a fast reverse transcription kit ((Beyotime Institute of Biotechnology). Real-time fluorescence quantitative PCR was used for the reaction (Bio‑Rad Laboratories, Inc.). The samples were amplified using the following thermocycling conditions: Initial denaturation at 95˚C for 30 sec; followed by 40 cycles of denaturation at 95˚C for 10 sec, annealing at 60˚C for 20 sec and elongation at 95˚C for 15 sec; and a final extension at 60˚C for 60 sec. The relative mRNA expression levels of the target genes were calculated as the fold change of the control using the 2‑ΔΔCq method (Livak et al., 2001). Primer sequences were used in Table 1.
