However, its influence on muscle aging has yet to be elucidated. The objective of this study was to investigate the effects of filbertone on muscle aging in C2C12 myotubes subjected to senescence induction by either doxorubicin or hydrogen peroxide. To ascertain the mechanisms by which filbertone exerts its effects, we conducted a series of experiments, including Western blot analysis, reverse transcription quantitative polymerase chain reaction (qRT-PCR), and senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) staining. Filbertone was markedly observed to decrease not only the protein levels of p53 (p &lt; 0.01) in senescence-induced skeletal muscle cells, but also the gene expression levels of p21 (p &lt; 0.05), a direct target of p53. The expression of muscle-related genes, including myogenin and muscle RING-finger protein-1 (MuRF1), was found to be significantly enhanced in senescent muscle cells following treatment with filbertone (p &lt; 0.05). In addition, the number of senescent skeletal muscle cells exhibiting \u03b2-galactosidase activity was found to be markedly reduced in the presence of filbertone (p &lt; 0.01). Collectively, these findings suggest that filbertone plays a pivotal role in the regulation of muscle aging.<\/jats:p>","DOI":"10.3390\/nu16183177","type":"journal-article","created":{"date-parts":[[2024,9,20]],"date-time":"2024-09-20T02:47:07Z","timestamp":1726800427000},"page":"3177","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Filbertone Reduces Senescence in C2C12 Myotubes Treated with Doxorubicin or H2O2 through MuRF1 and Myogenin"],"prefix":"10.3390","volume":"16","author":[{"given":"Sumin","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Food Science and Nutrition, University of Ulsan, Ulsan 44610, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9871-5180","authenticated-orcid":false,"given":"Byungyong","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Food Science and Nutrition, University of Ulsan, Ulsan 44610, Republic of Korea"},{"name":"Basic-Clinical Convergence Research Institute, University of Ulsan, Ulsan 44610, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1111\/apha.12532","article-title":"Skeletal muscle homeostasis and plasticity in youth and ageing: Impact of nutrition and exercise","volume":"216","author":"Brook","year":"2016","journal-title":"Acta Physiol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"427","DOI":"10.1152\/physrev.00061.2017","article-title":"Sarcopenia: Aging-Related Loss of Muscle Mass and Function","volume":"99","author":"Larsson","year":"2019","journal-title":"Physiol.
