Lep-ob\/ob mice were fed a control diet (CD) for 21 weeks (wks), or a high-fat diet (HFD) for 9 or 21 wks; in the 21 wk HFD groups, INT-787 (30 mg\/kg\/day) dosed via HFD admixture was added. The hepatic ATP, ROS, GSH and MIC19, which stabilizes the structure of inner mitochondrial membrane (IMM), were quantified. Transmission electron microscopy (TEM) analysis was also performed. INT-787 increased hepatic ATP, which was downregulated after HFD 9 and 21 wks. Hepatic ROS increased and GSH decreased after 21 wks and were recovered by INT-787. MIC19 mRNA level decreased after HFD 21 wks, and it was completely restored after INT-787 administration. TEM analysis showed that INT-787 reverted the mitochondrial alterations as documented by restored mitochondrial length, number of mitochondrial cristae junctions (CJs), and distance between endoplasmic reticulum (ER) and outer mitochondrial membrane (OMM) when compared with HFD groups. These results underline the involvement of the FXR pathway in the control of mitochondrial damage, thus revealing a previously undiscovered mechanism mediated by FXR activation: the upregulation of IMM protein MIC19, which is essential for maintaining cristae integrity and mitochondrial function.<\/jats:p>","DOI":"10.3390\/ijms262211023","type":"journal-article","created":{"date-parts":[[2025,11,14]],"date-time":"2025-11-14T10:07:03Z","timestamp":1763114823000},"page":"11023","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Farnesoid X Receptor Agonist INT-787 Inhibits Hepatic Mitochondrial Dysfunction in a Diet-Induced ob\/ob Mouse Model of MASH"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0103-1493","authenticated-orcid":false,"given":"Laura Giuseppina","family":"Di Pasqua","sequence":"first","affiliation":[{"name":"Department of Internal Medicine and Therapeutics, University of Pavia, Via Ferrata 9, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1312-7513","authenticated-orcid":false,"given":"Giuseppina","family":"Palladini","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Therapeutics, University of Pavia, Via Ferrata 9, 27100 Pavia, Italy"},{"name":"Internal Medicine and Emergency Medicine Unit, Fondazione IRCCS Policlinico San Matteo, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8996-2895","authenticated-orcid":false,"given":"Anna Cleta","family":"Croce","sequence":"additional","affiliation":[{"name":"Institute of Molecular Genetics, Italian National Research Council (CNR), Via Abbiategrasso 207, 27100 Pavia, Italy"},{"name":"Department of Biology & Biotechnology, University of Pavia, Via Ferrata 9, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0454-1416","authenticated-orcid":false,"given":"Gloria","family":"Milanesi","sequence":"additional","affiliation":[{"name":"Department of Biology & Biotechnology, University of Pavia, Via Ferrata 9, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7071-1996","authenticated-orcid":false,"given":"Margherita","family":"Cavallo","sequence":"additional","affiliation":[{"name":"Department of Biology & Biotechnology, University of Pavia, Via Ferrata 9, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8109-339X","authenticated-orcid":false,"given":"Luciano","family":"Adorini","sequence":"additional","affiliation":[{"name":"Intercept Pharmaceuticals, San Diego, CA 92121, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2337-2897","authenticated-orcid":false,"given":"Andrea","family":"Ferrigno","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Therapeutics, University of Pavia, Via Ferrata 9, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2464-6127","authenticated-orcid":false,"given":"Mariapia","family":"Vairetti","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Therapeutics, University of Pavia, Via Ferrata 9, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Degli Esposti, D., Hamelin, J., Bosselut, N., Saffroy, R., Sebagh, M., Pommier, A., Martel, C., and Lemoine, A.
