Several preclinical and clinical studies have been conducted to show the therapeutic potential of IGF-1, however, delivery issues, short half-life and isoform complexity have impose challenges. Antisense oligonucleotides (AONs) are able to downregulate target proteins by interfering with their transcripts. Here, we investigated the feasibility of enhancing IGF-1 signaling by downregulation of IGF-binding proteins. We observed that out of frame exon skipping of Igfbp1 and Igfbp3 downregulated their protein expression, which increased Akt phosphorylation on the downstream IGF-1 signaling in vitro. 3\u2019RNA sequencing analysis revealed the related transcriptome in C2C12 cells in response to IGFBP3 downregulation. The AONs did however not induce any exon skipping or protein knockdown in mdx mice after 6 weeks of systemic treatment. We conclude that IGFBP downregulation could be a good strategy to increase IGF-1 signaling but alternative tools are needed for efficient delivery and knockdown in vivo.<\/jats:p>","DOI":"10.3233\/jnd-230118","type":"journal-article","created":{"date-parts":[[2024,1,5]],"date-time":"2024-01-05T10:46:54Z","timestamp":1704451614000},"page":"299-314","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Antisense Oligonucleotide-Mediated Downregulation of IGFBPs Enhances IGF-1 Signaling"],"prefix":"10.1177","volume":"11","author":[{"given":"Alper","family":"Yavas","sequence":"first","affiliation":[{"name":"Department of Human Genetics, Leiden University Medical Center, Leiden, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maaike","family":"van Putten","sequence":"additional","affiliation":[{"name":"Department of Human Genetics, Leiden University Medical Center, Leiden, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annemieke","family":"Aartsma-Rus","sequence":"additional","affiliation":[{"name":"Department of Human Genetics, Leiden University Medical Center, Leiden, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,1,5]]},"reference":[{"key":"ref001","doi-asserted-by":"publisher","DOI":"10.1038\/s41572-021-00248-3"},{"key":"ref002","doi-asserted-by":"publisher","DOI":"10.4103\/1673-5374.253534"},{"key":"ref003","doi-asserted-by":"publisher","DOI":"10.1080\/21678707.2016.1240613"},{"key":"ref004","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(87)90579-4"},{"issue":"8","key":"ref005","first-page":"4488","volume":"12","author":"Ji G","year":"2020","journal-title":"American journal of translational research"},{"key":"ref006","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(96)70107-5"},{"key":"ref007","doi-asserted-by":"publisher","DOI":"10.1038\/nrg3460"},{"key":"ref008","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2017.04.010"},{"key":"ref009","doi-asserted-by":"publisher","DOI":"10.1089\/nat.2017.0682"},{"key":"ref010","doi-asserted-by":"publisher","DOI":"10.1038\/bjp.2008.153"},{"key":"ref011","doi-asserted-by":"publisher","DOI":"10.1016\/j.tem.2013.03.004"},{"issue":"8","key":"ref012","volume":"9","author":"Ahmad SS","year":"2020","journal-title":"Cells-Basel"},{"key":"ref013","doi-asserted-by":"publisher","DOI":"10.1016\/j.ghir.2012.02.004"},{"key":"ref014","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.200108071"},{"key":"ref015","doi-asserted-by":"publisher","DOI":"10.1002\/mus.26846"},{"key":"ref016","doi-asserted-by":"publisher","DOI":"10.3390\/ijms19061649"},{"issue":"21","key":"ref017","volume":"122","author":"Aharinejad S","year":"2010","journal-title":"Circulation"},{"key":"ref018","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0098641"},{"key":"ref019","doi-asserted-by":"publisher","DOI":"10.1677\/joe.0.1750019"},{"key":"ref020","doi-asserted-by":"publisher","DOI":"10.1016\/j.ghir.2013.03.001"},{"key":"ref021","doi-asserted-by":"publisher","DOI":"10.1016\/j.metabol.2017.04.013"},{"key":"ref022","doi-asserted-by":"publisher","DOI":"10.1186\/s13046-016-0317-z"},{"issue":"1","key":"ref023","first-page":"28","volume":"61","author":"Bach LA","year":"2018","journal-title":"T11-T"},{"key":"ref024","doi-asserted-by":"publisher","DOI":"10.1016\/j.tem.2013.03.004"},{"key":"ref025","doi-asserted-by":"publisher","DOI":"10.1002\/med.21706"},{"key":"ref026","doi-asserted-by":"publisher","DOI":"10.1159\/000517686"},{"key":"ref027","doi-asserted-by":"publisher","DOI":"10.31662\/jmaj.2021-0019"},{"key":"ref028","doi-asserted-by":"publisher","DOI":"10.1007\/s40265-017-0711-7"},{"key":"ref029","doi-asserted-by":"publisher","DOI":"10.1186\/1755-8794-4-36"},{"key":"ref030","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-61779-767-5_19"},{"key":"ref031","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/gkg595"},{"key":"ref032","doi-asserted-by":"publisher","DOI":"10.1089\/cmb.2017.0096"},{"key":"ref033","doi-asserted-by":"publisher","DOI":"10.1186\/s12859-018-2486-6"},{"key":"ref034","doi-asserted-by":"publisher","DOI":"10.1186\/s13059-014-0550-8"},{"key":"ref035","doi-asserted-by":"publisher","DOI":"10.1002\/jcp.10227"},{"key":"ref036","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/gkv007"},{"key":"ref037","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/gks042"},{"key":"ref038","doi-asserted-by":"publisher","DOI":"10.1210\/er.2008-0028"},{"issue":"9","key":"ref039","volume":"9","author":"Yoshida T","year":"2020","journal-title":"Cells-Basel"},{"key":"ref040","doi-asserted-by":"crossref","unstructured":"AllardJB, DuanCIGF-Binding Proteins: Why Do They Exist and Why Are There So Many?
