Track record

My clinician background is strengthened with knowledge on integrative of biology in exercise physiology, quantitative genetics and genomics. My scientific career has taken atypical paths allowing an integrative biology approach of functional genomics in muscular exercise in order to progress in animal and human health.

Fields of Research

Since 2004 my main research objective was to study muscular functional genomics in normal, pathological or treated muscle. Genomic functional disorders in two equine myopathies PSSM and RER were explored using expression microarrays and data mining methods.

In 2011, a scientific breakthrough in mitochondrial crosstalk was the discovery of pre-microRNAs and mature miRNAs encoded by the nuclear genome localized in mitochondria of human myocytes and the in silico prediction of putative miRNA sequences and targets on mtDNA. The paper has been published in PlosOne 2011:

Barrey E, Saint-Auret G, Bonnamy B, Damas D, Boyer O, Gidrol X. (2011) Pre-microRNA and mature microRNA in human mitochondria.PLoS One. 2011;6(5):e20220.

The metrics today indicated more than 15000 views, 42 citations. The results of this paper were confirmed by several other papers and new regulation functions of several miRNA localized to mitochondrial has been discovered. Recently, two miRNAs encoded  by the mitochondrial genome and derived from the 16S transcript were identified.  Other putative miRNAs derived from mtDNA transcription are studied in our team.   

Other Activites

Chaiman of international  conferences:

Innovation, transfer and consulting:

An original gait analysis systems based on body 3-dimensional acceleration measurements and softwares for automatic  gait analysis has been developped at INRA in the 90's for phenotyping horses exercise ability (Equimetrix®). A technological transfer has been performed for human medical and sports applications (Locometrix®). Medical applications in neurology, rehabilitation, geriatrics, rheumatology, physiotherapy and sport medicine are used in hospitals, rehabilitation centres in Europe. Locometrix® is used in ongoing clinical trials in myology. Co-founder and scientific consultant of Centaure Metrix, a start-up company lauched in 2001.
