Effects of chemerin/CMKLR1 in obesity-induced hypertension and potential mechanism.

Abstract Obesity-induced hypertension (OIH) has a high morbidity and mortality, and its prevention and treatment has been a major challenge in clinical practice. Chemerin is a newly discovered adipokine closely related to OIH. Male Wistar rats (8W) were divided into either a high-fat diet or a regular diet group. Body weight and blood pressure were measured every two weeks. After 20 weeks, serum, adipose tissue and aortic arteries were collected. Arterial tensions were detected; Immunohistochemistry, ELISA and Western blotting were used to detect the expression of chemerin, CMKLR1, Rock2 and P-MYPT1 in the aorta and perivascular adipose tissues. After 4 weeks, the body weight, systolic blood pressure, diastolic blood pressure and mean arterial pressure were all significantly higher in the high-fat diet group (P
