However, there is no published information about protein abundance of drug transporters measured using reliable protein quantification methods. Therefore, mRNA expression and absolute protein content of clinically relevant ABC (n = 6) and SLC (n = 15) family member transporters in the human parotid gland, using the qRT-PCR and liquid chromatography\u2012tandem mass spectrometry (LC\u2212MS\/MS) method, were studied. The abundance of nearly all measured proteins ranged between 0.04 and 0.45 pmol\/mg (OCT3 &gt; MRP1 &gt; PEPT2 &gt; MRP4 &gt; MATE1 &gt; BCRP). mRNAs of ABCB1, ABCC2, ABCC3, SLC10A1, SLC10A2, SLC22A1, SLC22A5, SLC22A6, SLC22A7, SLC22A8, SLCO1A2, SLCO1B1, SLCO1B3 and SLCO2B1 were not detected. The present study provides, for the first time, information about the protein abundance of membrane transporters in the human parotid gland, which could further be used to define salivary bidirectional transport (absorption and secretion) mechanisms of endogenous compounds and xenobiotics.<\/jats:p>","DOI":"10.3390\/ijms20194825","type":"journal-article","created":{"date-parts":[[2019,9,30]],"date-time":"2019-09-30T05:58:33Z","timestamp":1569823113000},"page":"4825","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Membrane Transporters in Human Parotid Gland-Targeted Proteomics Approach"],"prefix":"10.3390","volume":"20","author":[{"given":"Joanna","family":"Lapczuk-Romanska","sequence":"first","affiliation":[{"name":"Department of Experimental and Clinical Pharmacology, Pomeranian Medical University, ul.
