Background: Asthma is a common chronic inflammatory disease of the airway, and airway remodeling and the proliferation mechanism of airway smooth muscle cells (ASMCs) is of great significance to combat this disease.Objective: To assess possible effects of scopoletin on asthma and the potential signaling pathway.Materials and methods: ASMCs were treated PDGF-BB and scopoletin and subjected to cell viability detection by CCK-8 assay. Cell migration of ASMCs was determined by a wound closure assay and transwell assay. The protein level of MMP2, MMP9, calponin and α-SMA were measured using western blot. The levels of NF-κB signaling pathway were detected by Western blotting.Results: Scopoletin inhibited proliferation of PDGF-BB - induced ASMCs. Also it suppressed the migration and invasion of PDGF-BB - induced ASMCs. We further showed that Scopoletin regulated phenotypic transition of ASMCs. Mechanically, Scopoletin inhibited proliferation and invasion of ASMCs by regulating NF-κB signaling pathway.Conclusions: We therefore thought Scopoletin could serve as a promising drug for the treatment of asthma.

Proliferation And Migration

In this study we investigated the regulatory role of cell-migration-inducing and hyaluronan-binding protein (CEMIP) in the proliferation and migration of vascular smooth muscle cells (VSMCs). The mRNA and protein levels of CEMIP were upregulated in the plasma samples from patients with atherosclerosis, and in VSMCs stimulated with platelet-derived growth factor-BB (PDGF-BB), compared with plasma from healthy subjects and untreated VSMCs. Silencing CEMIP suppressed PDGF-BB-induced cell migration and proliferation in VSMCs, as determined using a Cell Counting Kit-8 assays, 5-ethynyl-2′-deocyuridine (EDU) assays, flow cytometry, wound healing assays, and Transwell assays. Overexpression of CEMIP promoted the proliferation and migration of VSMCs via activation of the Wnt–β-catenin signaling pathway and the upregulation of its target genes, including matrix metalloproteinase-2, matrix metalloproteinase-7, cyclin D1, and c-myc, whereas CEMIP deficiency showed the opposite effects. The knockdown of CEMIP in ApoE−/− mice by intravenous injection of lentiviral vector expressing si-CEMIP protected against high-fat-diet-induced atherosclerosis, as shown by the reduced aortic lesion areas, aortic sinus lesion areas, and the concentration of blood lipids compared with mice normally expressing CEMIP. These results demonstrated that CEMIP regulates the proliferation and migration of VSMCs in atherosclerosis by activating the WNT–β-catenin signaling pathway, which suggests the therapeutic potential of CEMIP for the management of atherosclerosis.
