Despite continuous research efforts, there are still no satisfactory or clinically effective pharmaceutical treatments for this condition. Accelerated inflammatory processes during aneurysm development lead to increased levels of matrix metalloproteinases (MMPs) and destabilization of the vessel wall through the degradation of the structural components of the extracellular matrix (ECM), mainly collagen and elastin. Tissue inhibitors of metalloproteinases (TIMPs) directly regulate MMP activity and consequently inhibit ECM proteolysis. In this work, the synthesis of TIMP-1 protein was increased by the exogenous delivery of synthetic TIMP-1 encoding mRNA into aortic vessel tissue in an attempt to inhibit MMP-9. In vitro, TIMP-1 mRNA transfection resulted in significantly increased TIMP-1 protein expression in various cells. The functionality of the expressed protein was evaluated in an appropriate ex vivo aortic vessel model. Decreased MMP-9 activity was detected using in situ zymography 24 h and 48 h post microinjection of 5 \u00b5g TIMP-1 mRNA into the aortic vessel wall. These results suggest that TIMP-1 mRNA administration is a promising approach for the treatment of aneurysms.<\/jats:p>","DOI":"10.3390\/ijms25126599","type":"journal-article","created":{"date-parts":[[2024,6,17]],"date-time":"2024-06-17T11:14:16Z","timestamp":1718622856000},"page":"6599","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["A Novel Strategy for the Treatment of Aneurysms: Inhibition of MMP-9 Activity through the Delivery of TIMP-1 Encoding Synthetic mRNA into Arteries"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8717-944X","authenticated-orcid":false,"given":"Sonia","family":"Golombek","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, University Hospital Tuebingen, Calwerstra\u00dfe 7\/1, 72076 Tuebingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabelle","family":"Doll","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, University Hospital Tuebingen, Calwerstra\u00dfe 7\/1, 72076 Tuebingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louisa","family":"Kaufmann","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, University Hospital Tuebingen, Calwerstra\u00dfe 7\/1, 72076 Tuebingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Lescan","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, University Hospital Tuebingen, Calwerstra\u00dfe 7\/1, 72076 Tuebingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Schlensak","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, University Hospital Tuebingen, Calwerstra\u00dfe 7\/1, 72076 Tuebingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4008-4272","authenticated-orcid":false,"given":"Meltem","family":"Avci-Adali","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, University Hospital Tuebingen, Calwerstra\u00dfe 7\/1, 72076 Tuebingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,15]]},"reference":[{"key":"ref_1","unstructured":"(2023, September 12).
