Abstract
BACKGROUND In chronic kidney disease (CKD) patients, increased levels of fibroblast growth factor 23 (FGF23) are associated with cardiovascular mortality. The relationship between FGF23 and heart hypertrophy has been documented, however, it is not known whether FGF23 has an effect on vasculature. Vascular smooth muscle cells VSMCs may exhibit different phenotypes; our hypothesis is that FGF23 favours a switch from a contractile to synthetic phenotype that may cause vascular dysfunction. Our objective was to determine whether FGF23 may directly control a change in VSMC phenotype. METHODS This study includes in vitro, in vivo and ex vivo experiments and evaluation of patients with CKD stages 2-3 studying a relationship between FGF23 and vascular dysfunction. RESULTS In vitro studies show that high levels of FGF23, by acting on its specific receptor FGFR1 and Erk1/2, causes a change in the phenotype of VSMCs from contractile to synthetic. This change is mediated by a downregulation of miR-221/222, which augments the expression of MAP3K2 and PAK1. miR-221/222 transfections recovered the contractile phenotype of VSMCs. Infusion of recombinant FGF23 to rats increased vascular wall thickness, with VSMCs showing a synthetic phenotype with a reduction of miR-221 expression. Ex-vivo studies on aortic rings demonstrate also that high FGF23 increases arterial stiffening. In CKD 2-3 patients, elevation of FGF23 was associated with increased pulse wave velocity and reduced plasma levels of miR-221/222. CONCLUSION In VSMCs, high levels of FGF23, through the downregulation of miR-221/222, causes a change to a synthetic phenotype. This change in VSMCs increases arterial stiffening and impairs vascular function, which might ultimately worsen cardiovascular disease.

J Clin Lab Anal 2021; 35:e23773. [PMID: 34767671 PMCID: PMC8649326 DOI: 10.1002/jcla.23773] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 12/24/2020] [Accepted: 03/20/2021] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND miR-145 is closely related to vascular smooth muscle cells (VSMC) phenotype transformation; however, the regulatory mechanisms through which miR-145 regulates the VSMC phenotype transformation under mechanical stretching are unclear. In this study, we evaluated the roles of miR-145 in VSMCs subjected to mechanical stretching in aortic dissection (AD). METHODS The expression of miR-145 in the aortic vessel wall of model animals and patients with AD was analyzed by quantitative polymerase chain reaction. miR-145-related protein-protein interaction networks and Wikipathways were used to analyze VSMC phenotypic transformation pathways regulated by miR-145. We used gain- and loss-of-function studies to evaluate the effects of miR-145 on VSMC differentiation under mechanical stretch induction and assessed whether Krüppel-like factor 4 (KLF4) was regulated by miR-145 in the aorta under mechanical stretch conditions. RESULTS miR-145 was abundantly expressed in the walls of the normal human aorta, but was significantly downregulated in animal models and the walls of patients with dissection. We found that contractile phenotype-related proteins were downregulated in VSMCs subjected to mechanical stretching, whereas the expression of secreted phenotype-related proteins increased. miR-145 overexpression also downregulated contractile phenotype-related proteins in VSMCs and suppressed upregulation of phenotype-related proteins. Finally, under mechanical stretching, KLF4 expression was significantly increased in VSMCs, and overexpression of miR-145 blocked this effect. CONCLUSION Our results confirmed that mechanical stretch-induced phenotypic transformation of VSMCs to promote AD via upregulation of KLF4; this mechanism was regulated by miR-145, which directly modulated KLF4 expression and VSMC differentiation.
