mRNA expression patterns of aminoacyl-tRNA synthetase-interacting multifunctional proteins (AIMPs) under normal and abnormal conditions of peripheral nerves. (a) Real-time quantitative PCR (qPCR) results showed mRNA expressions of AIMPs in sciatic nerves. Relative mRNA expressions of AIMPs were calculated by fold change; 1 was expression level of control sample (Con, not injured nerves). Fold changes of postinjury samples (3 days, 1 week, 2 weeks, 4 weeks) were derived by mRNA expression level of each sample divided by that of Con (n = 3, * p < 0.05, ** p < 0.01, *** p < 0.001, ns; p > 0.05). Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was used as loading control. (b) Semi-PCR results showed mRNA expressions of AIMPs in sciatic nerve.
