Improper sodium transport is a common comorbidity of hypertension, and sodium transport is also critical for maintaining the secretion of submandibular glands, whether the function of submandibular glands is affected by hypertension remains unclear. To determine whether hypertension induces changes in the protein expression of submandibular glands, we compared the proteome of submandibular glands from 14-week-old spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY) rats using LC-MS\/MS. The results revealed that 95 proteins displayed different levels of expression between the submandibular glands from the SHRs and WKYs. Among these, 35 proteins were more abundant, and 60 proteins were less abundant in the SHR compared with the WKY rats. Specifically, aquaporin 5 and parvalbumin, which are correlated with water transport and intracellular Ca<jats:sup>2+<\/jats:sup> signal transduction, were verified to exhibit differences in protein abundance. Impaired Ca<jats:sup>2+<\/jats:sup> response to carbachol was confirmed in the acinar cells from SHRs, and hyposecretion by the submandibular glands was further confirmed by <jats:italic>in vivo<\/jats:italic> saliva collection. In conclusion, the proteomic analysis of the submandibular glands of SHRs revealed novel changes in protein abundance that provides possible mechanisms connecting hypertension and hyposecretion in submandibular glands.<\/jats:p>","DOI":"10.1038\/s41598-017-15211-0","type":"journal-article","created":{"date-parts":[[2017,10,31]],"date-time":"2017-10-31T10:40:21Z","timestamp":1509446421000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Proteomic analysis reveals an impaired Ca2+\/AQP5 pathway in the submandibular gland in hypertension"],"prefix":"10.1038","volume":"7","author":[{"given":"Jing","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-Jun","family":"Zhong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-mei","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Cong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruo-Lan","family":"Xiang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-Ling","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guang-Yan","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2017,11,6]]},"reference":[{"key":"15211_CR1","doi-asserted-by":"publisher","unstructured":"Bie, P. & Evans, R.
