Abstract
Idiopathic pulmonary fibrosis (IPF) is a chronic, fatal lung disease characterized by progressive and non-reversible abnormal matrix deposition in lung parenchyma. Myofibroblasts origin mainly from resident fibroblasts via fibroblast-to-myofibroblast transition (FMT) are the dominant collagen-producing cells in pulmonary fibrosis. N6-methyladenosine (m6A) modification has been implicated in various biological process. However, the role of m6A modification in pulmonary fibrosis remains elusive. In this study, we reveal that m6A modification is up-regulated in bleomycin induced pulmonary fibrosis mice model, FMT-derived myofibroblasts and idiopathic pulmonary fibrosis patient lung samples. Lowering m6A level through silencing METTL3 inhibits FMT process in vitro and vivo. Mechanistically, KCNH6 is involved in m6A-regulated FMT process. m6A modification regulates the expression of KCNH6 by modulating its translation in a YTHDF1 dependent manner. Together, our study highlights the critical role of m6A modification in pulmonary fibrosis. Manipulation of m6A modification through targeting METTL3 may become a promising strategy for the treatment of pulmonary fibrosis.

Abstract
Skin injury is a common occurrence and mechanical forces are known to significantly impact the biological processes of skin regeneration and wound healing. Immediately following the disruption of the skin, the process of wound healing begins, bringing together numerous cell types to collaborate in several sequential phases. These cells produce a multitude of molecules and initiate multiple signaling pathways that are associated with skin disorders and abnormal wound healing, including hypertrophic scars, keloids, and chronic wounds. Studies have shown that mechanical forces can alter the microenvironment of a healing wound, causing changes in cellular function, motility, and signaling. A better understanding of the mechanobiology of cells in the skin is essential in the development of efficacious therapeutics to reduce skin disorders, normalize abnormal wound healing, and minimize scar formation.
