Abstract

Blood chemerin concentration shows positive correlation not only with body mass index and serum triglyceride level but also with systolic blood pressure. While it seems likely that chemerin influences vascular smooth muscle cell (SMC) proliferation and migration, which are crucial to the development of hypertension, this remains to be clarified. In the present study, we investigated whether chemerin controls SMC proliferation and migration in vitro and also affects blood pressure in vivo. In vitro, chemerin significantly stimulated rat mesenteric arterial SMC proliferation and migration, as determined by a cell counting assay and Boyden chamber assay, respectively. The migratory effect of chemerin was confirmed in human aortic SMCs. Chemerin significantly increased ROS production in SMCs and phosphorylation of Akt (Ser 473) and ERK, as measured by fluorescent staining and Western blot analysis, respectively. Various inhibitors (ROS inhibitor: N-acetyl-l-cysteine, phosphatidylinositol 3-kinase inhibitor: LY-294002, MAPKK inhibitor: PD-98059, NADPH oxidase inhibitor: gp91 ds-tat, and xanthine oxidase inhibitor: allopurinol) as well as chemokine-like receptor 1 small interfering RNA significantly inhibited chemerin-induced SMC proliferation and migration. Furthermore, chemerin-neutralizing antibody prevented carotid neointimal hyperplasia in the mouse ligation model. In vivo, chronic chemerin treatment (6 μg/kg, 6 wk) increased systolic blood pressure as well as phosphorylation of Akt and ERK in the mouse isolated aorta. In summary, we, for the first time, demonstrate that chemerin/chemokine-like receptor 1 stimulates SMC proliferation and migration via ROS-dependent phosphorylation of Akt/ERK, which may lead to vascular structural remodeling and an increase in systolic blood pressure.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
