RECK and pulmonary fibrosis: In a bleomycin (BLM)-induced pulmonary fibrosis model, miR-497-5p was upregulated, and suppressing miR-497-5p expression using a lentiviral agent in vivo reduced the expression of fibrotic markers Mmp2, Mmp9 and Tgfb1 via enhancing the expression of Reck, suggesting augmented in vivo lung repair.
