The mechanisms by which these diseases affect skeletal muscle metabolism need to be deeply explored. By analyzing the miRNA expression profiles in the plasma of patients with COPD, we found that miR-191 expression was significantly altered and it may influence skeletal muscle metabolism by regulating ubiquitination and the mTOR pathway. Using a mouse model of skeletal muscle injury induced by cardiotoxin, we found that miR-191 and\n                    <jats:italic>Wwp1<\/jats:italic>\n                    showed a dynamic negative correlation in injury repair. Transfection with miR-191 mimics significantly inhibited the expression of myogenic regulatory factor Myog and differentiation markers Myh1\/7\/8, while downregulating key genes in the mTOR pathway. Molecular mechanism studies showed that miR-191 could directly act on the 3\u2019 untranslated region of the\n                    <jats:italic>Wwp1<\/jats:italic>\n                    gene to inhibit its expression. This study reveals the important role of the miR-191\/Wwp1 axis in skeletal muscle differentiation and provides a novel theoretical basis for research on muscle atrophy induced by COPD, cancer cachexia, and other diseases.\n                  <\/jats:p>","DOI":"10.1371\/journal.pone.0355370","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T17:27:55Z","timestamp":1788974875000},"page":"e0355370","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["miR-191 affects skeletal muscle differentiation by regulating Wwp1 in mouse myoblasts"],"prefix":"10.1371","volume":"21","author":[{"given":"Wenhua","family":"Pu","sequence":"first","affiliation":[{"name":"Inner Mongolia Key Laboratory of Life Health and Bioinformatics, School of Life Science and Technology, Inner Mongolia University of Science & Technology","place":["Baotou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meimei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Ordos Central Hospital","place":["Ordos, China"],"department":["Department of Geriatrics"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siman","family":"Guo","sequence":"additional","affiliation":[{"name":"Inner Mongolia Key Laboratory of Life Health and Bioinformatics, School of Life Science and Technology, Inner Mongolia University of Science & Technology","place":["Baotou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Bao","sequence":"additional","affiliation":[{"name":"Ordos Central Hospital","place":["Ordos, China"],"department":["Department of Geriatrics"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjia","family":"Cui","sequence":"additional","affiliation":[{"name":"Inner Mongolia Key Laboratory of Life Health and Bioinformatics, School of Life Science and Technology, Inner Mongolia University of Science & Technology","place":["Baotou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5451-5550","authenticated-orcid":true,"given":"Chuncheng","family":"Liu","sequence":"additional","affiliation":[{"name":"Inner Mongolia Key Laboratory of Life Health and Bioinformatics, School of Life Science and Technology, Inner Mongolia University of Science & Technology","place":["Baotou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"pone.0355370.ref001","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1159\/000448247","article-title":"Oral Drugs Related with Muscle Wasting and Sarcopenia.
