    Mitochondrial oxidation of hydrogen sulfide (H2S)

    Hydrogen sulfide (H2S) is a gas released by volcanoes or by anaerobic ecosystems including the gut microbiota. Normal cellular metabolism also generates H2S.

    H2S, NO, CO and cyanide are extremely toxic molecules because they inhibit mitochondrial respiration. Curiously, NO, CO and H2S are also known gasotransmitters regulating the cardiovascular system as well as other processes such as inflammation.

    H2S is a source of electrons for a Sulfide Quinone Reductase (SQR) found in sulfo-oxidant bacteria and in mitochondria. H2S is consumed avidly by most mitochondria when present at nM to µM concentration and preferably to any other organic molecule. These characteristics avoid H2S accumulation and poisoning.

    Our main objective is to address the role of the mitochondrial sulfide oxidation pathway in physiological as well as in pathological states. Two very different situations are studied. The first is related to sulfide toxicity. It is essentially encountered in gut because of the sulfo-reductant bacteria of the microbiota. There the question is whether overwhelming the anti-sulfide defense of the gut has deleterious consequences such as inflammation, DNA damage, cancer. The second situation deals with the relationships between sulfide signaling and oxidation, which is modulated in most tissues by SQR.

    Research interests


    In collaboration with the group of F. Blachier (AgroParisTech) we showed that sulfide oxidation pathway is almost ubiquitous. It is obviously highly represented in colonic tissues. It is present in most tissues and cultured cells but, notably, absent in brain tissues and neuroblastoma cell lines. Furthermore we demonstrated that sulfide oxidation occurs at low micromolar concentration and takes precedence over other respiratory substrates
    (Biochim Biophys Acta. 2010 Aug;1797(8):1500-11Nitric Oxide. 2014 Sep 15;41:105-12.)

    We evidenced that the amount of respiratory chain complexes, and not that of the sulfide oxidation pathway, is the determinant factor for the enhanced sulfide tolerance of colonic cells upon their differentiation( Antioxid Redox Signal. 2012 Jul 1;17(1):1-10)

    We reviewed the data that support the overlap between toxic/trophic and signaling effect of sulfide (Br J Pharmacol. 2014 Apr;171(8):2099-122). In that context, we recently showed that the sulfide oxidation capacity of human liver can greatly vary. We evaluated its relevance to the individual blood pressure maintenance (Nitric Oxide. 2014 Sep 15;41:105-12)
