Angus-cross heifers (n = 43) were estrus synchronized, bred via artificial insemination, and assigned at breeding to 1 of 2 dietary intake groups (CON = 100% of requirements to achieve 0.45 kg\/d of BW gain or RES = 60% of CON intake) and ovariohysterectomized on day 16, 34, or 50 of gestation (n = 6 to 9\/d) in a completely randomized design with a 2 \u00d7 3 factorial arrangement of treatments. Uterine cross-sections were collected from the horn ipsilateral to the corpus luteum, fixed in 10% neutral buffered formalin, sectioned at 5 \u00b5m, and stained via immunofluorescence for transporters. For each image, areas of fetal membrane (FM; chorioallantois), luminal epithelium (ENDO), superficial glands (SG), deep glands (DG), and myometrium (MYO) were analyzed separately for relative intensity of fluorescence as an indicator of transporter abundance. Analysis of FM was only conducted for days 34 and 50. No transporters in target areas were influenced by a day \u00d7 treatment interaction (P \u2265 0.06). In ENDO, all transporters were differentially abundant from days 16 to 50 of gestation (P \u2264 0.04), and SLC7A2 was greater (P = 0.05) for RES vs. CON. In SG, SLC7A1 and SLC7A2 were greater (P \u2264 0.04) at day 34 vs. day 16. In DG, SLC2A3 and SLC7A1 were greater (P \u2264 0.05) for CON vs. RES heifers; furthermore, SLC7A1 was greater (P &amp;lt; 0.01) at day 50 vs. days 16 and 34 of gestation. In MYO, SLC7A1 was greater (P &amp;lt; 0.01) for CON vs. RES and was greater (P = 0.02) at days 34 and 50 vs. day 16. There were no differences in FM (P \u2265 0.06). Analysis of all uterine tissues at day 16 determined that SLC2A1, SLC2A3, and SLC7A2 were all differentially abundant across uterine tissue type (P &amp;lt; 0.01), and SLC7A1 was greater (P = 0.02) for CON vs. RES. Analysis of all uteroplacental tissues at days 34 and 50 demonstrated that all transporters differed (P &amp;lt; 0.01) across uteroplacental tissues, and SLC7A1 was greater (P &amp;lt; 0.01) for CON vs. RES. These data are interpreted to imply that transporters are differentially affected by day of gestation, and that hexose and cationic amino acid transporters are differentially abundant across utero-placental tissue types, and that SLC7A1 is responsive to maternal nutritional treatment.<\/jats:p>","DOI":"10.1093\/jas\/skaa386","type":"journal-article","created":{"date-parts":[[2020,11,28]],"date-time":"2020-11-28T16:46:48Z","timestamp":1606582008000},"source":"Crossref","is-referenced-by-count":11,"title":["The effects of maternal nutrition during the first 50 d of gestation on the location and abundance of hexose and cationic amino acid transporters in beef heifer uteroplacental tissues"],"prefix":"10.1093","volume":"99","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4579-2737","authenticated-orcid":false,"given":"Matthew S","family":"Crouse","sequence":"first","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyle J","family":"McLean","sequence":"additional","affiliation":[{"name":"Department of Animal Science, University of Tennessee, Knoxville, TN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josephine","family":"Dwamena","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6642-9449","authenticated-orcid":false,"given":"Tammi L","family":"Neville","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana Clara B","family":"Menezes","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alison K","family":"Ward","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lawrence P","family":"Reynolds","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4556-4315","authenticated-orcid":false,"given":"Carl R","family":"Dahlen","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bryan W","family":"Neville","sequence":"additional","affiliation":[{"name":"Carrington Research Extension Center, Carrington, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pawel P","family":"Borowicz","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joel S","family":"Caton","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Center for Nutrition and Pregnancy, North Dakota State University, Fargo, ND"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,11,28]]},"reference":[{"key":"2021020216351479200_CIT0001","doi-asserted-by":"crossref","first-page":"315","DOI":"10.1002\/iub.315","article-title":"The protein family of glucose transport facilitators: it\u2019s not only about glucose after all","volume":"62","author":"Augustin","year":"2010","journal-title":"IUBMB Life"},{"key":"2021020216351479200_CIT0002","doi-asserted-by":"crossref","first-page":"1094","DOI":"10.1095\/biolreprod.111.094722","article-title":"Uterine histotroph and conceptus development: select nutrients and secreted phosphoprotein 1 affect mechanistic target of rapamycin cell signaling in ewes","volume":"85","author":"Bazer","year":"2011","journal-title":"Biol.
