Despite the progress, few options are available to assess translation in live animals, as their complexity limits the repertoire of experimental tools to monitor and manipulate processes within organs and individual cells. It this study, we developed a labeling-free method for measuring organ- and cell-type-specific translation elongation rates in vivo. It is based on time-resolved delivery of translation initiation and elongation inhibitors in live animals followed by ribosome profiling. It also reports translation initiation sites in an organ-specific manner. Using this method, we found that the elongation rates differ more than 50% among mouse organs and determined them to be 6.8, 5.0\u00a0and 4.3 amino acids per second for liver, kidney, and skeletal muscle, respectively. We further found that the elongation rate is reduced by 20% between young adulthood and mid-life. Thus, translation, a major metabolic process in cells, is tightly regulated at the level of elongation of nascent polypeptide chains.<\/jats:p>","DOI":"10.1093\/nar\/gkaa1103","type":"journal-article","created":{"date-parts":[[2020,10,27]],"date-time":"2020-10-27T16:13:46Z","timestamp":1603815226000},"page":"e9-e9","source":"Crossref","is-referenced-by-count":97,"title":["Translation elongation rate varies among organs and decreases with age"],"prefix":"10.1093","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8396-2202","authenticated-orcid":false,"given":"Maxim V","family":"Gerashchenko","sequence":"first","affiliation":[{"name":"Division of Genetics, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zalan","family":"Peterfi","sequence":"additional","affiliation":[{"name":"Division of Genetics, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8050-5775","authenticated-orcid":false,"given":"Sun Hee","family":"Yim","sequence":"additional","affiliation":[{"name":"Division of Genetics, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0372-7016","authenticated-orcid":false,"given":"Vadim N","family":"Gladyshev","sequence":"additional","affiliation":[{"name":"Division of Genetics, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,12,2]]},"reference":[{"key":"2021012319511416800_B1","doi-asserted-by":"crossref","first-page":"90","DOI":"10.1016\/j.cell.2018.02.036","article-title":"Ribosome levels selectively regulate translation and lineage commitment in human hematopoiesis","volume":"173","author":"Khajuria","year":"2018","journal-title":"Cell"},{"key":"2021012319511416800_B2","doi-asserted-by":"crossref","first-page":"eaan2755","DOI":"10.1126\/science.aan2755","article-title":"Ribosomopathies: There's strength in numbers","volume":"358","author":"Mills","year":"2017","journal-title":"Science"},{"key":"2021012319511416800_B3","doi-asserted-by":"crossref","first-page":"5236","DOI":"10.1172\/JCI124282","article-title":"Slowing ribosome velocity restores folding and function of mutant CFTR","volume":"129","author":"Oliver","year":"2019","journal-title":"J.
