However, whether lncRNAs interact with miRNAs to form an interrelated regulatory network in IPF remains unknown.30 In the current study, we presented a novel, highly expressed lnc-PCF that can promote the proliferation of activated epithelial cells by competitively binding to miR-344a-5p-targeted map3k11 in pulmonary fibrosis (Figure 8). Here, MAP3K11 is linked to pulmonary fibrosis.
