However,\n                    the effects of antidiabetic medications on STRs, downstream molecules, and\n                    glucose transporters expression are unknown. In our study, ZDF rats\n                    (n=24) were randomly treated by metformin (MET,\n                    215.15\u2009mg\/kg), sitagliptin (SIT, 10.76\u2009mg\/kg),\n                    or saline for 4 weeks. Fasting blood glucose and insulin levels were measured,\n                    and HOMA-IR and QUICKI index were calculated. One week later, we detected\n                    relative mRNA expression of T1R2\/T1R3, \u03b1-gustducin, TRPM5 and\n                    glucose transporters including SGLT1, SGLT2, and GLUT2 in the small intestine\n                    and kidney. We found that though both metformin and sitagliptin effectively\n                    decreased fasting blood glucose, only metformin improved HOMA-IR and QUICKI\n                    (p&lt;0.05). MRNA levels of STRs and sweet taste molecules in duodenum and\n                    jejunum were not different among three groups, but those in ileum were\n                    dramatically upregulated after SIT (vs. MET p&lt;0.05; vs. CON\n                    p&lt;0.01). SGLT1 and GLUT2 in ileum were markedly increased after SIT\n                    (p&lt;0.01). In the kidney, expression of SGLT2 and GLUT2 were\n                    downregulated in both SIT and MET group (p&lt;0.05). In conclusion,\n                    metformin and sitagliptin exerted different effects on expression of STRs and\n                    glucose transporters in the gut and kidney. STRs, downstream molecules, and\n                    glucose transporters in distal small intestinal were sensitively increased in\n                    response to sitagliptin than metformin treatment. Renal glucose transporters\n                    were downregulated after metformin and sitagliptin treatment.<\/jats:p>","DOI":"10.1055\/a-1135-9031","type":"journal-article","created":{"date-parts":[[2020,4,6]],"date-time":"2020-04-06T23:02:53Z","timestamp":1586214173000},"page":"329-335","source":"Crossref","is-referenced-by-count":4,"title":["Effects of Metformin and Sitagliptin Monotherapy on Expression of\n                    Intestinal and Renal Sweet Taste Receptors and Glucose Transporters in a Rat\n                    Model of Type 2 Diabetes"],"prefix":"10.1055","volume":"52","author":[{"given":"Minchun","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Endocrinology and Metabolism, Renji Hospital, School of\n                    Medicine, Shanghai Jiaotong University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rilu","family":"Feng","sequence":"first","affiliation":[{"name":"Department of Endocrinology and Metabolism, Renji Hospital, School of\n                    Medicine, Shanghai Jiaotong University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiang","family":"Yue","sequence":"first","affiliation":[{"name":"Department of Endocrinology and Metabolism, Renji Hospital, School of\n                    Medicine, Shanghai Jiaotong University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng","family":"Qian","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Renji Hospital, School of\n                    Medicine, Shanghai Jiaotong University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Renji Hospital, School of\n                    Medicine, Shanghai Jiaotong University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Renji Hospital, School of\n                    Medicine, Shanghai Jiaotong University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher K.","family":"Rayner","sequence":"additional","affiliation":[{"name":"Centre of Research Excellence in Translating Nutritional Science to\n                    Good Health, University of Adelaide, Adelaide, Australia"},{"name":"Department of Gastroenterology and Hepatology, Royal Adelaide Hospital,\n                    Adelaide, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, Renji Hospital, School of\n                    Medicine, Shanghai Jiaotong University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2020,4,6]]},"container-title":["Hormone and Metabolic Research"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-1135-9031.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,5,13]],"date-time":"2020-05-13T22:33:41Z","timestamp":1589409221000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-1135-9031"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,4,6]]},"references-count":0,"journal-issue":{"issue":"05","published-online":{"date-parts":[[2020,5,13]]},"published-print":{"date-parts":[[2020,5]]}},"URL":"https:\/\/doi.org\/10.1055\/a-1135-9031","relation":{},"ISSN":["0018-5043","1439-4286"],"issn-type":[{"value":"0018-5043","type":"print"},{"value":"1439-4286","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,4,6]]}}}
