YTHDC1 and pulmonary fibrosis: To explore the role of YTHDC1 in IPF, we constructed pulmonary fibrosis mice model by intratracheal instillation of bleomycin (BLM), which is the most extensively used animal model that recapitulates critical features of human IPF (Liu et al, 2017), and detected the protein levels of YTHDC1 in lung tissue by immunofluorescence (IF).
