Résumé

Carnitine palmitoyltransferase-2 () is a mitochondrial enzyme involved in long-chain fatty acid entry into mitochondria for their β-oxidation and energy production. Two phenotypes are associated with the extremely reduced activity in genetically deficient patients: neonatal lethality or, in milder forms, myopathy. Resveratrol (RSV) is a phytophenol produced by grape plant in response to biotic or abiotic stresses that displays anti-oxidant properties, in particular through AP-1, NFκB, STAT-3, and COX pathways. Some beneficiary effects of RSV are due to its modulation of microRNA (miRNA) expression. RSV can enhance residual activities in human fibroblasts derived from -deficient patients and restores normal fatty acid oxidation rates likely through stimulation of mitochondrial biogenesis. Here, we report changes in miRNA expression linked to -deficiency, and we identify miRNAs whose expression changed following RSV treatment of control or -deficient fibroblasts isolated from patients. Our findings suggest that RSV consumption might exert beneficiary effects in patients with -deficiency.
