DPP-4 gene and protein expression in muscle tissue isolated from LDH patients and AIS patients. A, B Relative expression of DPP4 and STAT1 was significantly decreased in patients (n = 45) as compared with that of the controls (n = 30). C mRNA expression level of DPP4 gene were strongly correlated with STAT1 mRNA expression level (r = 0.41, p < 0.05). Pearson’s correlation analysis was used to determine the correlation. D, E Western blot showed DPP-4 protein expression in muscle was significantly higher in controls (n = 4) as compared with AIS patients (n = 4). *p < 0.05, two-tailed Student’s t test. Data are presented as mean ± standard deviation
