    Objective

     

    Inherited mitochondrial diseases, defined as the diseases due to an OXHOS defect, have an estimated prevalence of 1/5000 individuals. They have very diverse clinical presentations in accordance to their multiple causes with gene mutations located either in the mitochondrial or nuclear genome. Our main objective is to address the pathophysiological mechanisms of mitochondrial diseases to understand the extreme phenotypic diversity of these diseases and to find potential therapeutic avenues.

    The group

    Karine Auré, MCU-PH AP-HP researcher, Claude Jardel, PH AP-HP researcher, Caroline L’hermitte-Stead, lab assistant, and Nathalie Le Foll, PhD student (in co-supervision with Pr Wolf) are involved in the project.

     

    Research interests

     

    We have a strong interest in clinical research, in particular in genotype/phenotype relationship. Within that interest we recently showed that diseases due to defective mitochondrial DNA maintenance related to mutations of either POLG or TK2 nuclear genes presented with a reproducible set of signs/symptoms but that their rate of progression could considerably vary from early onset rapidly lethal cases to late onset slowly progressive diseases (Tchikviladze 2015, Neeve 2012, Béhin 2012). The search for the underlying genetic modifying factors is undertaken within an international collaboration.

    Our second main interest resides in the molecular mechanisms of mitochondrial diseases that we most often analyze in cells derived from patients. We deciphered the mitochondrial consequences of OPA1 mutations associated with autosomal dominant optic atrophy (Agier 2012) and identified a new cause for severe congenital lactic acidosis with cytochrome c oxidase defect (Weraarpachai 2012).

    We recently described that mutations of mitochondrial DNA genes encoding subunits of the ATP synthase (complex V of the OXPHOS pathway) were responsible for an original phenotype associating recurrent accesses of paralysis and progressive degeneration of motor neurons (Auré et al Neurology 2013). Permanent depolarization of cultured fibroblasts plasma membrane provided a molecular substratum for the accesses of paralysis while bioenergetic consequences of the complex V defect essentially impacted the metabolism of reactive oxygen species. The molecular mechanisms associated with these particular mutations are addressed in different cellular models including fibroblasts, cybrids and neuronal precursor cells derived from induced pluripotent stem cells obtained from the patients’ fibroblasts.
