Meldonium regulates glycolytic enzymes and pyruvate metabolism in vivo and in vitro. (A) Representative spots of meldonium target proteins, including the glycolytic process. MD: meldonium. (B) mRNA expression of PFKP, PKM2, LDHA, and PDK1 in RLE-6TN cells (n = 4–5). (C) Protein expression of PFKP, PKM2, LDHA, PDH, and PDK1 in RLE-6TN cells (n = 4). (D) Protein expression of PFKP, PKM2, LDHA, and PDK1 in lungs of mice after hypoxia for 24 h (n = 6–7). Data are expressed as the mean ± SEM. Statistical analyses were performed using one-way ANOVA followed by Fisher’s LSD test. #p < 0.05, ##p < 0.01, ###p < 0.001 compared with the control group; *p < 0.05, **p < 0.01 compared with the hypoxia group.
