Regulatory effect of miR-149 on interleukin-6 expression in silica-induced pulmonary fibrosis

Objective To investigate the regulatory effect of miR-149 on interleukin-6(IL-6)expression in silica-induced pulmonary fibrosis.Methods A mouse model of pulmonary fibrosis was established using silica dust;the level of miR-149 in the lung tissues of mice with silicainduced pulmonary fibrosis was measured by
