Spontaneously hypertensive rats (SHR) were administered water, Captopril (50 mg\/kg) or Hpp11 at different doses (25, 55 and 85 mg\/kg), and the systolic blood pressure (SBP) was recorded. The SBP of normotensive Wistar-Kyoto (WKY) rats administered water or Hpp11 was also recorded. Additionally, plasmatic angiotensin-converting enzyme (ACE) activity was determined in the SHR administered Hpp11. Moreover, the relaxation caused by Hpp11 in isolated aortic rings from Sprague-Dawley rats was evaluated. Hpp11 exhibited antihypertensive activity at doses of 55 and 85 mg\/kg, with maximum activity 6 h post-administration. At this time, no differences were found between these doses and Captopril. Initial SBP values of 55 and 85 mg\/kg were recovered 24 or 8 h post-administration, respectively, 55 mg\/kg being the most effective dose. At this dose, a reduction in the plasmatic ACE activity in the SHR was found. However, Hpp11 did not relax the aortic ring preparations. Therefore, ACE inhibition could be the mechanism underlying Hpp11 antihypertensive effect. Remarkably, Hpp11 did not modify SBP in WKY rats, showing that the decreased SBP effect is specific to the hypertensive state.<\/jats:p>","DOI":"10.3390\/nu10091295","type":"journal-article","created":{"date-parts":[[2018,9,13]],"date-time":"2018-09-13T11:46:04Z","timestamp":1536839164000},"page":"1295","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Dose-Related Antihypertensive Properties and the Corresponding Mechanisms of a Chicken Foot Hydrolysate in Hypertensive Rats"],"prefix":"10.3390","volume":"10","author":[{"given":"Anna","family":"Mas-Capdevila","sequence":"first","affiliation":[{"name":"Nutrigenomics Research Group, Department of Biochemistry and Biotechnology, Universitat Rovira i Virgili, 43007 Tarragona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zara","family":"Pons","sequence":"additional","affiliation":[{"name":"Nutrigenomics Research Group, Department of Biochemistry and Biotechnology, Universitat Rovira i Virgili, 43007 Tarragona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amaya","family":"Aleixandre","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, School of Medicine, Universidad Complutense de Madrid, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6468-3088","authenticated-orcid":false,"given":"Francisca I.","family":"Bravo","sequence":"additional","affiliation":[{"name":"Nutrigenomics Research Group, Department of Biochemistry and Biotechnology, Universitat Rovira i Virgili, 43007 Tarragona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7384-8588","authenticated-orcid":false,"given":"Bego\u00f1a","family":"Muguerza","sequence":"additional","affiliation":[{"name":"Nutrigenomics Research Group, Department of Biochemistry and Biotechnology, Universitat Rovira i Virgili, 43007 Tarragona, Spain"},{"name":"Technological Unit of Nutrition and Health, EURECAT-Technology Centre of Catalonia, 43204 Reus, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"591","DOI":"10.1016\/S0140-6736(07)61299-9","article-title":"Essential hypertension","volume":"370","author":"Messerli","year":"2007","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1061","DOI":"10.1038\/ki.2011.46","article-title":"Non-pharmacological aspects of blood pressure management: What are the data?","volume":"79","author":"Hedayati","year":"2011","journal-title":"Kidney Int."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"417","DOI":"10.3390\/md10020417","article-title":"Antihypertensive effect of long-term oral administration of jellyfish (Rhopilema esculentum) collagen peptides on renovascular hypertension","volume":"10","author":"Zhuang","year":"2012","journal-title":"Mar.
