The goal of this study was to analyse the biochemical profiles of embryonic fluids and blood plasma of rabbits with and without insulin-dependent diabetes mellitus (DT1), to identify metabolic changes associated with maternal diabetes mellitus in early pregnancy. Insulin-dependent diabetes was induced by alloxan treatment in female rabbits 10 days before mating. On day 6 post-coitum, plasma and blastocoel fluid (BF) were analysed by ultrahigh performance liquid chromatography-tandem mass spectroscopy (UPLC-MS\/MS) (Metabolon Inc. Durham, NC, USA). Metabolic datasets comprised a total of 284 and 597 compounds of known identity in BF and plasma, respectively. Diabetes mellitus had profound effects on maternal and embryonic metabolic profiles, with almost half of the metabolites changed. As predicted, we observed an increase in glucose and a decrease in 1,5-anhydroglucitol in diabetic plasma samples. In plasma, fructose, mannose, and sorbitol were elevated in the diabetic group, which may be a way of dealing with excess glucose. In BF, metabolites of the pentose metabolism were especially increased, indicating the need for ribose-based compounds relevant to DNA and RNA metabolism at this very early stage of embryo development. Other changes were more consistent between BF and plasma. Both displayed elevated acylcarnitines, body3-hydroxybutyrate, and multiple compounds within the branched chain amino acid metabolism pathway, suggesting that lipid beta-oxidation is occurring at elevated levels in the diabetic group. This study demonstrates that maternal and embryonic metabolism are closely related. Maternal diabetes mellitus profoundly alters the metabolic profile of the preimplantation embryo with changes in all subclasses of metabolites.<\/jats:p>","DOI":"10.3390\/ijms21030919","type":"journal-article","created":{"date-parts":[[2020,1,31]],"date-time":"2020-01-31T05:55:46Z","timestamp":1580450146000},"page":"919","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Metabolic Profiling in Blastocoel Fluid and Blood Plasma of Diabetic Rabbits"],"prefix":"10.3390","volume":"21","author":[{"given":"Maria","family":"Schindler","sequence":"first","affiliation":[{"name":"Institute of Anatomy and Cell Biology, Martin Luther University Faculty of Medicine, Grosse Steinstrasse 52, D-06097 Halle (Saale), Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophia Mareike","family":"Pendzialek","sequence":"additional","affiliation":[{"name":"Institute of Anatomy and Cell Biology, Martin Luther University Faculty of Medicine, Grosse Steinstrasse 52, D-06097 Halle (Saale), Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarzyna","family":"Grybel","sequence":"additional","affiliation":[{"name":"Institute of Anatomy and Cell Biology, Martin Luther University Faculty of Medicine, Grosse Steinstrasse 52, D-06097 Halle (Saale), Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom","family":"Seeling","sequence":"additional","affiliation":[{"name":"Institute of Anatomy and Cell Biology, Martin Luther University Faculty of Medicine, Grosse Steinstrasse 52, D-06097 Halle (Saale), Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne","family":"Navarrete Santos","sequence":"additional","affiliation":[{"name":"Institute of Anatomy and Cell Biology, Martin Luther University Faculty of Medicine, Grosse Steinstrasse 52, D-06097 Halle (Saale), Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1002\/(SICI)1098-2795(199601)43:1<105::AID-MRD13>3.0.CO;2-4","article-title":"What is the relationship between the metabolism of preimplantation embryos and their developmental competence?","volume":"43","author":"Barnett","year":"1996","journal-title":"Mol.
