NF-κB down-regulated miR-194 expression in ALI induced by LPS. a Expression of miR-194 in mice measured by RT-qPCR; b Activity of NF-κB in LPS-treated macrophages detected by ELISA and the expression of NF-κBp65, extent of NF-κBp65 phosphorylation in LPS-treated macrophages assessed by western blot analysis; c Expression of miR-194 in LPS-treated macrophages measured by RT-qPCR. The data in the figures were measurements, which were expressed as mean ± standard deviation; data between different groups were compared by unpaired t-test. *, p < 0.05
