BALB\/c and C57BL\/6 healthy and tumor-bearing mice were exposed to a control (1000 IU), low- (100 IU), and high- (5000 IU) vitamin D3 diets. Additionally, from day 7 of tumor transplantation, the 1000 and 100 IU groups were gavaged with calcitriol (+cal). After 8 weeks of feeding, plasma levels of 25(OH)D3, 24,25(OH)2D3, and 3-epi-25(OH)D3 were significantly lower in calcitriol-treated and vitamin D-deficient groups than in the control, whereas the levels of all metabolites were increased in the 5000 IU group. The ratio of 25(OH)D3:24,25(OH)2D3 was increased in both calcitriol-treated groups, whereas the ratio of 25(OH)D3:3-epi-25(OH)D3 was increased only in the 100 IU group but decreased in the 5000 IU group. In contrast to E0771, 4T1 lung metastasis was accelerated in all vitamin D-supplemented mice, as well as in the deficient group with an increased inflammatory response. 67NR tumor growth was transiently inhibited in the 1000 IU+cal group, but single metastases were observed in the 5000 and 100 IU groups. Based on the results, we conclude that various schemes of vitamin D supply and vitamin D deficiency led to similar metabolite profiles irrespective of the mice strain and tumor burden. However, depending on the type of breast cancer, different effects on tumor growth and metastasis were noticed.<\/jats:p>","DOI":"10.3390\/nu12113416","type":"journal-article","created":{"date-parts":[[2020,11,8]],"date-time":"2020-11-08T19:03:37Z","timestamp":1604862217000},"page":"3416","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Vitamin D Metabolite Profile in Cholecalciferol- or Calcitriol-Supplemented Healthy and Mammary Gland Tumor-Bearing Mice"],"prefix":"10.3390","volume":"12","author":[{"given":"Artur","family":"Anisiewicz","sequence":"first","affiliation":[{"name":"Department of Experimental Oncology, Hirszfeld Institute of Immunology and Experimental Therapy, 53-114 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konrad","family":"Kowalski","sequence":"additional","affiliation":[{"name":"Research and Development Center Masdiag, 01-882 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanna","family":"Banach","sequence":"additional","affiliation":[{"name":"Department of Experimental Oncology, Hirszfeld Institute of Immunology and Experimental Therapy, 53-114 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3320-0415","authenticated-orcid":false,"given":"Natalia","family":"\u0141ab\u0119d\u017a","sequence":"additional","affiliation":[{"name":"Department of Experimental Oncology, Hirszfeld Institute of Immunology and Experimental Therapy, 53-114 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0170-9436","authenticated-orcid":false,"given":"Martyna","family":"Stachowicz-Suhs","sequence":"additional","affiliation":[{"name":"Department of Experimental Oncology, Hirszfeld Institute of Immunology and Experimental Therapy, 53-114 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4093-7386","authenticated-orcid":false,"given":"Aleksandra","family":"Piotrowska","sequence":"additional","affiliation":[{"name":"Department of Histology and Embryology, Faculty of Medicine, Wroclaw Medical University, 50-368 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6696-5305","authenticated-orcid":false,"given":"Magdalena","family":"Milczarek","sequence":"additional","affiliation":[{"name":"Department of Experimental Oncology, Hirszfeld Institute of Immunology and Experimental Therapy, 53-114 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1574-1106","authenticated-orcid":false,"given":"Dagmara","family":"K\u0142opotowska","sequence":"additional","affiliation":[{"name":"Department of Experimental Oncology, Hirszfeld Institute of Immunology and Experimental Therapy, 53-114 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8292-1385","authenticated-orcid":false,"given":"Piotr","family":"Dzi\u0119giel","sequence":"additional","affiliation":[{"name":"Department of Histology and Embryology, Faculty of Medicine, Wroclaw Medical University, 50-368 Wroclaw, Poland"},{"name":"Department of Physiotherapy, Wroclaw University School of Physical Education, 51-612 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4980-6606","authenticated-orcid":false,"given":"Joanna","family":"Wietrzyk","sequence":"additional","affiliation":[{"name":"Department of Experimental Oncology, Hirszfeld Institute of Immunology and Experimental Therapy, 53-114 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"342","DOI":"10.1038\/nrc3691","article-title":"The role of vitamin D in reducing cancer risk and progression","volume":"14","author":"Feldman","year":"2014","journal-title":"Nat.
