Astaxanthin attenuates cardiovascular dysfunction associated with deoxycorticosterone acetate-salt-induced hypertension in rats.
Background: Hypertension is a major global health problem. It is a major risk factor of cardiovascular disease. One of the most used experimental models in studying antihypertensive action is the deoxycorticosterone acetate (DOCA)-salt hypertensive rat. This study aimed to investigate the cardiovascular protective effect of astaxanthin (ASX) in DOCA-salt-induced hypertension and its possible underlying mechanisms.
Methods: A total of 48 adult male Wistar albino rats were divided into three groups: control, DOCA, and DOCA + ASX. Blood pressure, serum cardiac enzyme levels, some oxidative stress and inflammatory biomarker levels, and lipid profile levels were measured. The weight of the left ventricle to tibial length ratio was calculated. Apoptosis detection and total genomic DNA extraction in aortic and cardiac tissues were investigated. The apoptotic marker BAX was also immunohistochemically assessed in the heart and aorta.
Results: Compared to the control group, the DOCA group was associated with a significant increase in blood pressure, serum cardiac enzyme levels, oxidative stress and inflammatory biomarker levels, lipid profile except serum high-density lipoprotein (HDL), weight of the left ventricle to tibial length, and total released DNA fragmentation level of the left ventricle and aorta and a significant decrease in reduced glutathione (GSH) and HDL. Compared to the DOCA group, the DOCA + ASX group significantly improved the DOCA-induced changes.
Conclusion: ASX has beneficial protective effects on DOCA-salt-induced hypertension via DNA fragmentation protection, apoptosis inhibition, antioxidant, anti-inflammatory, and its effects on lipid levels.
期刊介绍：
Clinical and Experimental Hypertension is a reputable journal that has converted to a full Open Access format starting from Volume 45 in 2023. While previous volumes are still accessible through a Pay to Read model, the journal now provides free and open access to its content. It serves as an international platform for the exchange of up-to-date scientific and clinical information concerning both human and animal hypertension. The journal publishes a wide range of articles, including full research papers, solicited and unsolicited reviews, and commentaries. Through these publications, the journal aims to enhance current understanding and support the timely detection, management, control, and prevention of hypertension-related conditions.
One notable aspect of Clinical and Experimental Hypertension is its coverage of special issues that focus on the proceedings of symposia dedicated to hypertension research. This feature allows researchers and clinicians to delve deeper into the latest advancements in this field.
The journal is abstracted and indexed in several renowned databases, including Pharmacoeconomics and Outcomes News (Online), Reactions Weekly (Online), CABI, EBSCOhost, Elsevier BV, International Atomic Energy Agency, and the National Library of Medicine, among others. These affiliations ensure that the journal's content receives broad visibility and facilitates its discoverability by professionals and researchers in related disciplines.
