Although targeting ER stress is an attractive avenue for treatment and has proven successful in the treatment of a related skeletal dysplasia, to date no drugs have proven successful in reducing ER stress in EDM5 caused by the retention of mutant matrilin-3. Our exciting findings show that by using our established luciferase ER stress screening assay, we can identify a \u201cnatural\u201d chemical, curcumin, which is able to reduce pathological ER stress in a cell model of EDM5 by promoting the proteasomal degradation mutant matrilin-3. Therefore, this is an important in vitro study in which we describe, for the first time, the success of a naturally occurring chemical as a potential treatment for this currently incurable rare skeletal disease. As studies show that curcumin can be used as a potential treatment for range of diseases in vitro, current research is focused on developing novel delivery strategies to enhance its bioavailability. This is an important and exciting area of research that will have significant clinical impact on a range of human diseases including the rare skeletal disease, EDM5.<\/jats:p>","DOI":"10.3390\/ijms24021496","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T05:45:33Z","timestamp":1673502333000},"page":"1496","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Curcumin Reduces Pathological Endoplasmic Reticulum Stress through Increasing Proteolysis of Mutant Matrilin-3"],"prefix":"10.3390","volume":"24","author":[{"given":"Ella P.","family":"Dennis","sequence":"first","affiliation":[{"name":"International Centre for Life, Biosciences Institute, Newcastle University, Newcastle upon Tyne NE1 3BZ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robyn N.","family":"Watson","sequence":"additional","affiliation":[{"name":"International Centre for Life, Biosciences Institute, Newcastle University, Newcastle upon Tyne NE1 3BZ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florence","family":"McPate","sequence":"additional","affiliation":[{"name":"International Centre for Life, Biosciences Institute, Newcastle University, Newcastle upon Tyne NE1 3BZ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael D.","family":"Briggs","sequence":"additional","affiliation":[{"name":"International Centre for Life, Biosciences Institute, Newcastle University, Newcastle upon Tyne NE1 3BZ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1038\/ng573","article-title":"Mutations in the region encoding the von Willebrand factor A domain of matrilin-3 are associated with multiple epiphyseal dysplasia","volume":"28","author":"Chapman","year":"2001","journal-title":"Nat.
