Similar transport processes were involved in the uptake from the 3 transcobalamins; uptake was dependent on the presence of calcium ions, cellular respiration and free sulphydryl groups. These results suggest that contrary to current belief, all 3 transcobalamins play a role in the transfer of vitamin B&lt;sub&gt;12&lt;\/sub&gt; to tissue cells.<\/jats:p>","DOI":"10.1159\/000208057","type":"journal-article","created":{"date-parts":[[2009,3,4]],"date-time":"2009-03-04T06:05:48Z","timestamp":1236146748000},"page":"89-94","source":"Crossref","is-referenced-by-count":6,"title":["Role of Transcobalamins I, II and III in the Transfer of Vitamin B\n                    <sub>12<\/sub>\n                    to Human Bone Marrow Cells in vitro"],"prefix":"10.1159","author":[{"given":"S.N.","family":"Wickramasinghe","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.M.","family":"England","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.E.","family":"Saunders","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.C.","family":"Down","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,3,3]]},"container-title":["Acta Haematologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/208057","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000208057","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T12:42:01Z","timestamp":1777466521000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000208057"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,3,3]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000208057","archive":["Portico"],"relation":{},"ISSN":["0001-5792","1421-9662"],"issn-type":[{"value":"0001-5792","type":"print"},{"value":"1421-9662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,3,3]]}}}
