Rutin lowered arterial pressure and expressions of angiotensin converting enzyme, angiotensin 2 type 1 receptor, and mineralocorticoid receptor in uninephrectomized hypertensive rats.
Does rutin reduce arterial pressure and inhibit ACE/ATR1/MCR signaling in uninephrectomized hypertensive rats?
Rutin demonstrates antihypertensive properties in a rat model by inhibiting ACE, ATR1, and mineralocorticoid receptor signaling pathways.
Hypertension is the most common cardiovascular disease that affects approximately 26% of adult population, worldwide. Rutin is one of the important flavonoids that is consumed in the daily diet, and found in many food items, vegetables, and beverages. Uninephrectomy (UNX) of the left kidney was performed, followed by induction of hypertension. The rats were randomly divided into four groups of 10 rats: group 1-Sham-operated rats; group 2-UNX rats, group 3-UNX-L-NAME (40 mg/kg) plus rutin (100 mg/kg bwt), and groups 4-UNX-L-NAME plus lisinopril (10 mg/kg bwt), orally for 3 weeks. Results revealed significant heightening of arterial pressure and oxidative stress indices, while hypertensive rats treated with rutin had lower expressions of angiotensin converting enzyme (ACE) and mineralocorticoid receptor in uninephrectomized rats. Together, rutin as a novel antihypertensive flavonoid could provide an unimaginable benefits for the management of hypertension through inhibition of angiotensin converting enzyme and mineralocorticoid receptor. PRACTICAL APPLICATIONS: Hypertension has been reported to be the most common cardiovascular disease, affecting approximately 26% of the adult population worldwide with predicted prevalence to increase by 60% by 2025. Recent advances in phytomedicine have shown flavonoids to be very helpful in the treatment of many diseases. Flavonoids have been used in the treatment and management of cardiovascular diseases, obesity and hypertension. The study revealed that rutin, a known flavonoid inhibited angiotensin converting enzyme (ACE), angiotensin 2 type 1 receptor (ATR1), and mineralocorticoid receptor (MCR), comparable to the classic ACE inhibitor, Lisinopril, indicating the novel antihypertensive property of rutin. Therefore, flavonoids such as rutin found in fruits and vegetables could, therefore, serve as an antihypertensive drug regimen. Combining all, functional foods rich in flavonoids could be used as potential therapeutic candidates for managing uninephrectomized hypertensive patients.
Oyagbemi et al. (Wed,) conducted a other in Hypertension (n=40). Rutin vs. Sham, UNX, and UNX-L-NAME plus lisinopril was evaluated on Arterial pressure, oxidative stress indices, and expressions of ACE, ATR1, and MCR. Rutin lowered arterial pressure and expressions of angiotensin converting enzyme, angiotensin 2 type 1 receptor, and mineralocorticoid receptor in uninephrectomized hypertensive rats.
