CFLAR and idiopathic pulmonary fibrosis: In this study, we further determined the role of miR-34a on FLIP expression in human IPF lung myofibroblasts, in vitro, and in mouse lung myofibroblasts in vitro and in vivo, following Bleomycin-induced lung injury in chimeric-miR-34aKO mice, with miR-34aKO specifically in mesenchymal cells, compared to their WT counterparts.
