This marks the second such declaration in the past 2 years in response to the MPXV transmission. The re\u2010emergence of the MPXV 3 years after the start of the SARS\u2010CoV\u20102 epidemic further emphasizes the need to develop broad spectrum antivirals that might control the spread of poorly understood pathogens. The induction of innate immune responses to a viral infection triggers rapid expression of type\u2010I\u2010interferon, which subsequently leads to the differential regulation of over 300 genes that collectively establish an antiviral state. While most of these \u201cinterferon\u2010stimulated genes\u201d (ISGs) are upregulated, some are downregulated. Notably, the expression of certain ISGs involved in lipid metabolism is suppressed, which can be exploited by viruses to facilitate their replication. Herein, we report that the expression of fatty acid synthase (FASN), an enzyme involved in de novo biosynthesis of fatty acids, was significantly reduced upon MPXV infection. Moreover, MPXV infection was impaired in FASN knockout cells, and biological inhibitors of FASN significantly inhibited MPXV. Interestingly, chosterol\u201025\u2010hydroxylase was induced in MPXV\u2010infected cells, and its enzymatic product, 25\u2010hydroxychlosterol (25HC), blocked MPXV infection. Overall, this study suggests that 25HC and FASN inhibitors exhibit significant antiviral activity and may have therapeutic applications in combating understudied infectious diseases in early outbreak settings when targeted therapies have not yet been developed.<\/jats:p>","DOI":"10.1002\/jmv.70403","type":"journal-article","created":{"date-parts":[[2025,5,30]],"date-time":"2025-05-30T05:35:40Z","timestamp":1748583340000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Suppression of Monkeypox Virus by Downregulation of Fatty Acid Synthase and Upregulation of Cholesterol\u201025 Hydroxylase"],"prefix":"10.1002","volume":"97","author":[{"given":"Saba R.","family":"Aliyari","sequence":"first","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics University of California, Los Angeles Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean","family":"Shanaa","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics University of California, Los Angeles Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics University of California, Los Angeles Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mari","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics University of California, Los Angeles Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaitlyn N.","family":"Bateman","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics University of California, Los Angeles Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lulan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics University of California, Los Angeles Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael E.","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry University of California, Los Angeles Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6713-2783","authenticated-orcid":false,"given":"Genhong","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology and Molecular Genetics University of California, Los Angeles Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,5,30]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.28036"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/v12111257"},{"key":"e_1_2_7_4_1","unstructured":"Mpox (Monkeypox) Outbreak 2022.https:\/\/www.who.int\/emergencies\/situations\/monkeypox-oubreak-2022."},{"key":"e_1_2_7_5_1","article-title":"Monkeypox: A Review of Clinical Features, Diagnosis, and Treatment","volume":"14","author":"Cheema A.
