In this study, we explored possible interactions between BMP6, serotonin, and glucose metabolism regulation. The effect of BMP6 or 5HT on pancreatic \u03b2-cells has been studied in vitro using the INS-1 832\/13 rat insulinoma cell line. Studies in vivo have been performed on mice with the global deletion of the Bmp6 gene (BMP6\u2212\/\u2212) and included glucose and insulin tolerance tests, gene expression studies using RT-PCR, immunohistochemistry, and ELISA analyses. We have shown that BMP6 and 5HT treatments have the opposite effect on insulin secretion from INS-1 cells. The effect of BMP6 on the 5HT system in vivo depends on the tissue studied, with no observable systemic effect on peripheral 5HT metabolism. BMP6 deficiency does not cause diabetic changes, although a mild difference in insulin tolerance test between BMP6\u2212\/\u2212 and WT mice was observed. In conclusion, BMP6 does not directly influence glucose metabolism, but there is a possibility that its deletion causes slowly developing changes in glucose and serotonin metabolism, which would become more expressed with ageing.<\/jats:p>","DOI":"10.3390\/ijms25147842","type":"journal-article","created":{"date-parts":[[2024,7,18]],"date-time":"2024-07-18T08:39:12Z","timestamp":1721291952000},"page":"7842","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Influence of BMP6 on Serotonin and Glucose Metabolism"],"prefix":"10.3390","volume":"25","author":[{"given":"Marina","family":"Mile\u0161evi\u0107","sequence":"first","affiliation":[{"name":"Laboratory for Mineralized Tissues, Center for Translational and Clinical Research, School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivona","family":"Mati\u0107 Jeli\u0107","sequence":"additional","affiliation":[{"name":"Laboratory for Mineralized Tissues, Center for Translational and Clinical Research, School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5982-2557","authenticated-orcid":false,"given":"Viktorija","family":"Rumenovi\u0107","sequence":"additional","affiliation":[{"name":"Laboratory for Mineralized Tissues, Center for Translational and Clinical Research, School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Ivanjko","sequence":"additional","affiliation":[{"name":"Laboratory for Mineralized Tissues, Center for Translational and Clinical Research, School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4076-0285","authenticated-orcid":false,"given":"Slobodan","family":"Vuki\u010devi\u0107","sequence":"additional","affiliation":[{"name":"Laboratory for Mineralized Tissues, Center for Translational and Clinical Research, School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2306-6152","authenticated-orcid":false,"given":"Tatjana","family":"Bordukalo-Nik\u0161i\u0107","sequence":"additional","affiliation":[{"name":"Laboratory for Mineralized Tissues, Center for Translational and Clinical Research, School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"846480","DOI":"10.1155\/2013\/846480","article-title":"Endocrine actions of osteocalcin","volume":"2013","author":"Patti","year":"2013","journal-title":"Int.
