    Abstract:
    Apelin, an endogenous ligand of the G-protein-coupled receptor APJ, is expressed in a diverse number of organs. The apelin-APJ axis helps to control the processes of pathological and physiological fibrosis, including renal fibrosis, cardiac fibrosis, liver fibrosis and pulmonary fibrosis. However, the role of apelin-APJ in organ fibrosis remains controversial due to conflicting study results. The apelin-APJ axis is a detrimental mechanism which promotes liver fibrosis mainly via up-regulation the expression of collagen-II and platelet-derived growth factor receptor β (PDGFRβ). On the contrary, the apelin-APJ axis is beneficial for renal fibrosis, cardiac fibrosis and pulmonary fibrosis. The apelin-APJ axis alleviates renal fibrosis by restraining the expression of transforming growth factor-β1 (TGF-β1). In addition, the apelin-APJ axis attenuates cardiac fibrosis through multiple pathways. Furthermore, the apelin-APJ axis has beneficial effects on experimental bronchopulmonary dysplasia (BPD) and acute respiratory distress syndrome (ARDS) which suggest the apelin-APJ axis potentially alleviates pulmonary fibrosis. In this article, we review the controversies associated with apelin-APJ in organ fibrosis and introduce the drugs that target apelin-APJ. We conclude that future studies should place more emphasis on the relationship among apelin isoforms, APJ receptor subtypes and organ fibrosis. The apelin-APJ axis will be a potential therapeutic target and those drugs targeted for apelin-APJ may constitute a novel therapeutic strategy for renal fibrosis, cardiac fibrosis, liver fibrosis and pulmonary fibrosis.
