A better understanding of the molecular mechanism underlying this apparent bioenergetic deficiency state may reveal insights for developing targeted treatment strategies. We report that overexpression of\n                    <jats:italic>Wiskott-Aldrich Syndrome Protein Family Member 3<\/jats:italic>\n                    (\n                    <jats:italic>WASF3<\/jats:italic>\n                    ), here identified in a 38-y-old woman suffering from long-standing fatigue and exercise intolerance, can disrupt mitochondrial respiratory supercomplex formation and is associated with endoplasmic reticulum (ER) stress. Increased expression of\n                    <jats:italic>WASF3<\/jats:italic>\n                    in transgenic mice markedly decreased their treadmill running capacity with concomitantly impaired respiratory supercomplex assembly and reduced complex IV levels in skeletal muscle mitochondria. WASF3 induction by ER stress using endotoxin, well known to be associated with fatigue in humans, also decreased skeletal muscle complex IV levels in mice, while decreasing WASF3 levels by pharmacologic inhibition of ER stress improved mitochondrial function in the cells of the patient with chronic fatigue. Expanding on our findings, skeletal muscle biopsy samples obtained from a cohort of patients with ME\/CFS showed increased WASF3 protein levels and aberrant ER stress activation. In addition to revealing a potential mechanism for the bioenergetic deficiency in ME\/CFS, our study may also provide insights into other disorders associated with fatigue such as rheumatic diseases and long COVID.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2302738120","type":"journal-article","created":{"date-parts":[[2023,8,14]],"date-time":"2023-08-14T15:06:41Z","timestamp":1692025601000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":37,"title":["WASF3 disrupts mitochondrial respiration and may mediate exercise intolerance in myalgic encephalomyelitis\/chronic fatigue syndrome"],"prefix":"10.1073","volume":"120","author":[{"given":"Ping-yuan","family":"Wang","sequence":"first","affiliation":[{"name":"Cardiovascular Branch, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Ma","sequence":"additional","affiliation":[{"name":"Cardiovascular Branch, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5130-4413","authenticated-orcid":false,"given":"Young-Chae","family":"Kim","sequence":"additional","affiliation":[{"name":"Cardiovascular Branch, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annie Y.","family":"Son","sequence":"additional","affiliation":[{"name":"Cardiovascular Branch, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0725-2609","authenticated-orcid":false,"given":"Abu Mohammad","family":"Syed","sequence":"additional","affiliation":[{"name":"Cardiovascular Branch, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5136-9225","authenticated-orcid":false,"given":"Chengyu","family":"Liu","sequence":"additional","affiliation":[{"name":"Transgenic Core, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1349-6378","authenticated-orcid":false,"given":"Mateus P.","family":"Mori","sequence":"additional","affiliation":[{"name":"Cardiovascular Branch, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca D.","family":"Huffstutler","sequence":"additional","affiliation":[{"name":"Cardiovascular Branch, National Heart, Lung, and Blood Institute, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JoEllyn L.","family":"Stolinski","sequence":"additional","affiliation":[{"name":"NIH MRI Research Facility, National Institute of Neurological Disorders and Stroke, NIH, Bethesda, MD 20892"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
