Sarcopenia, a condition characterized by the loss of muscle, is generally present in cachexia and is associated with inflammation. M2 macrophages, also known as an anti-inflammatory or alternatively activated macrophages, have been shown to play a role in muscle repair. Magnoliae Cortex (M.C) is a widely used medicinal herb in East Asia reported to have a broad range of anti-inflammatory activities; however, the effects of M.C on sarcopenia and on M2 macrophage polarization have to date not been studied. This study was designed to investigate whether the oral administration of M.C could decrease cisplatin-induced sarcopenia by modulating M2 macrophage polarization in mice. C57BL\/6 mice were injected intraperitoneally with cisplatin (2.5 mg\/kg) to mimic chemotherapy-induced sarcopenia. M.C extract (50, 100, and 200 mg\/kg) was administered orally every 3 days (for a total of 12 times). M.C (100 and 200 mg\/kg) significantly alleviated the cisplatin-induced loss of body mass, skeletal muscle weight, and grip strength. In addition, M.C increased the expression of M2 macrophage markers, such as MRC1, CD163, TGF-\u03b2, and Arg-1, and decreased the expression of M1-specific markers, including NOS2 and TNF-\u03b1, in skeletal muscle. Furthermore, the levels of like growth factor-1(IGF-1), as well as the number of M2a and M2c macrophages, significantly increased in skeletal muscle after M.C administration. M.C did not interfere with the anticancer effect of cisplatin in colon cancer. Our results demonstrated that M.C can alleviate cisplatin-induced sarcopenia by increasing the number of M2 macrophages. Therefore, our findings suggest that M.C could be used as an effective therapeutic agent to reverse or prevent cisplatin-induced sarcopenia.<\/jats:p>","DOI":"10.3390\/ijms22063188","type":"journal-article","created":{"date-parts":[[2021,3,21]],"date-time":"2021-03-21T22:00:37Z","timestamp":1616364037000},"page":"3188","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Magnoliae Cortex Alleviates Muscle Wasting by Modulating M2 Macrophages in a Cisplatin-Induced Sarcopenia Mouse Model"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2972-7505","authenticated-orcid":false,"given":"Minwoo","family":"Hong","sequence":"first","affiliation":[{"name":"Department of Science in Korean Medicine, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8145-6645","authenticated-orcid":false,"given":"Ik-Hwan","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Physiology, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilseob","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Science in Korean Medicine, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nari","family":"Cha","sequence":"additional","affiliation":[{"name":"Department of Science in Korean Medicine, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8494-4524","authenticated-orcid":false,"given":"Woojin","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Science in Korean Medicine, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"},{"name":"Department of Physiology, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sun Kwang","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Science in Korean Medicine, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"},{"name":"Department of Physiology, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0299-3582","authenticated-orcid":false,"given":"Hyunsu","family":"Bae","sequence":"additional","affiliation":[{"name":"Department of Science in Korean Medicine, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"},{"name":"Department of Physiology, College of Korean Medicine, Kyung Hee University, 26-6 Kyungheedae-ro, Dongdaemun-gu, Seoul 02453, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2920","DOI":"10.1158\/1078-0432.CCR-08-2242","article-title":"Sarcopenia as a Determinant of Chemotherapy Toxicity and Time to Tumor Progression in Metastatic Breast Cancer Patients Receiving Capecitabine Treatment","volume":"15","author":"Prado","year":"2009","journal-title":"Clin.
