TLR4 and ischemia: When miRNA expression was compared in the muscle samples of C57BL/6 and Tlr4−/−/NF-κB−/− mice subjected to 2 h of ischemia and 1 d of reperfusion, only 3 miRNAs (miR-15a, miR-744, and miR-1196) showed significantly increased expression in C57BL/6 mice and decreased expression in Tlr4−/−/NF-κB−/− mice (Table 2).
