In this study, traditional medicinal plant extracts were tested for cultured human melanocyte proliferation, migration, and melanogenesis using MTT, scratch wound-healing assays, transmission electron microscopy, immunofluorescence staining, and Western blot technology. Of the methanolic extracts, <jats:italic>Lycium shawii<\/jats:italic> L. (<jats:italic>L. shawii<\/jats:italic>) extract increased melanocyte proliferation at low concentrations and modulated melanocyte migration. At the lowest tested concentration (i.e., 7.8\u00a0\u03bcg\/mL), the <jats:italic>L. shawii<\/jats:italic> methanolic extract promoted melanosome formation, maturation, and enhanced melanin production, which was associated with the upregulation of microphthalmia-associated transcription factor (MITF), tyrosinase, tyrosinase-related protein (TRP)-1 and TRP-2 melanogenesis-related proteins, and melanogenesis-related proteins. After the chemical analysis and <jats:italic>L. shawii<\/jats:italic> extract-derived metabolite identification, the <jats:italic>in silico<\/jats:italic> studies revealed the molecular interactions between Metabolite 5, identified as apigenin (4,5,6-trihydroxyflavone), and the copper active site of tyrosinase, predicting enhanced tyrosinase activity and subsequent melanin formation. In conclusion, <jats:italic>L. shawii<\/jats:italic> methanolic extract stimulates melanocyte functions, including melanin production, and its derivative Metabolite 5 enhances tyrosinase activity, suggesting further investigation of the <jats:italic>L. shawii<\/jats:italic> extract-derived Metabolite 5 as a potential natural drug for vitiligo treatment.<\/jats:p>","DOI":"10.3389\/fphar.2023.1169812","type":"journal-article","created":{"date-parts":[[2023,4,24]],"date-time":"2023-04-24T04:32:42Z","timestamp":1682310762000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Stimulatory effects of Lycium shawii on human melanocyte proliferation, migration, and melanogenesis: In vitro and in silico studies"],"prefix":"10.3389","volume":"14","author":[{"given":"Khalid","family":"Alghamdi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zeyad","family":"Alehaideb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashok","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamad","family":"Al-Eidi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sahar S.","family":"Alghamdi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rasha","family":"Suliman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rizwan","family":"Ali","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feras","family":"Almourfi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saleh M.","family":"Alghamdi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed","family":"Boudjelal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabine","family":"Matou-Nasri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,4,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"778","DOI":"10.1111\/pcmr.12878","article-title":"The enigma and challenges of vitiligo pathophysiology and treatment","volume":"33","author":"Abdel-Malek","year":"2020","journal-title":"Pigment.
