Investigation of the relationship between serum adropin levels, oxidative stress biomarkers, and blood pressure in DOCA-salt hypertensive rats
DOCA-salt hypertension and adropin
Keywords:Adropin, Oxidative stress, DOCA-salt hypertension, Blood pressure
Background/Aim: Adropin is involved in the pathophysiology and development of cardiovascular diseases, such as hypertension. The aim of this study was to investigate the effects of adropin in serum, potential use as a biochemical biomarker of oxidative stress, and effects on blood pressure in deoxycorticosterone acetate (DOCA) salt hypertensive rats.
Methods: Eighteen male Sprague-Dawley rats were divided into two groups: (1) Control (C) and (2) Hypertensive (H). Systolic and diastolic blood pressures (SBP and DBP, respectively), and mean blood pressure (MBP) were measured using the tail-cuff method. At the end of the study, serum endothelin-1 (ET-1), adropin, nitric oxide (NO), total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) were also analyzed.
Results: Significant increases in SBP, DBP, MBP, cardiac hypertrophy index (CHI), and left ventricular hypertrophy index (LVCI) in the H group compared with the C group were found. Serum levels of ET-1, TOS, and OSI were significantly higher in the H group and serum levels of NO, adropin, and TAS were lower than in the C group. A negative correlation between serum adropin levels and the variables SBP, DBP, MBP, TOS, OSI, CHI, and LVHI was found. Adropin levels were positively correlated positively with serum NO levels in both groups.
Conclusion: Serum adropin levels decreased in hypertensive DOCA-salt rats. Lower serum adropin levels were found to be significantly associated with hypertension and may play a role in this disease. However, further comprehensive and diverse studies are needed.
