International audience; Ciguatoxins are lipid-soluble polyether compounds produced by dinoflagellates from the genus Gambierdiscus spp.. Ciguatoxins are mostly found in tropical and subtropical zones; however, within the last decade, they have been identified in fishes caught in European waters, notably in Madeira (1) and Canary Islands (2), while Gambierdiscus spp. have also been found both in the NE Atlantic Ocean (3) and in the Mediterranean Sea (4). These toxins bind to Voltage Gated Sodium Channels at the surface of human sensory neurons where they remain, causing Ciguatera Fish Poisoning with a variety of gastrointestinal, cardiovascular and neurological symptoms (paresthesia, ataxia, cold allodynia), including persistent neurological effects. Ciguatera is the major cause of food poisonings by seafood worldwide, with an estimated 50 000 to 500 000 victims per year. However, there is so far no simple and quick way of detecting these toxins in contaminated samples. Currently, only heavy and expensive laboratory methods are available to detect them: LC-MS/MS, receptor-binding assays by competition with radiolabeled compounds, and neuroblastoma cell-based assays performed on mammalian neurons (5). We have started to engineer biosensors based on the detection of a transcriptional signal in the yeast model Saccharomyces cerevisiae. This unicellular eukaryotic model is well-known and easy to genetically modify, grows fast and presents a very good conservation of signaling pathways with higher eukaryotes. We present a series of genetically modified yeast strains which allow us to follow the activation of specific signaling pathways responding linearly to ciguatoxin exposure. This pre-exploratory project received a seed-funding by CNRS (PEPs project, Océasafe). References : 1 Otero et al., Anal. Chem. 2010, 82, 6032 2 Nuñez et al., 2012.

[³H]SSR-1494 15 is the first tritiated nonpeptide vasopressin V
1b receptor (V1b R) antagonist Iigand. It was used for studying rodent (mouse, rat, hamster) and human V1b R from native or recombinant origin. Moreover, a close comparison between the human and the mouse V1b R was performed using SSR-149415/[³H]SSR-149415 in binding and functional studies in vitro. [³H]SSR-149415 binding was time-dependent, reversible, and saturable. Scatchard plot analysis gave a single class of high-affinity binding sites with apparent equilibrium dissociation constant (Kd ) ~1 nM and maximum binding density (Bmax ) values from 7,000 to 300,000 sites/cell according to the cell line. In competition experiments, [³H]SSR-149415 binding was stereospecific and dose-dependently displaced by reference peptide and nonpeptide arginine vasopressin (AVP)/OT ligands following a V1b rank order of affinity: SSR-149415 = AVP > dCha > dPen > dPal > dDavp > SSR-126768A > SR-49059 > SSR-149424 > OT > SR-121463B. Species differences between human, rat, mouse, and hamster V1b R were observed. Autoradiography studies with [³H]SSR-149415 on rat and human pituitary showed intense specific labeling confined to corticotroph cells and absence of labeling in the other tissues examined. SSR-149415 potently and stereospecifically antagonized the AVP-induced inositol phosphate production and intracellular Ca2+ increase (EC50 from 1.83 to 3.05 nM) in recombinant cell lines expressing either the mouse or the human V1b R. AVP (10-7 M) exposure of AtT20 cells expressing mouse or human EGFP-tagged V1b R induced their rapid internalization. Preincubation with 10-6 M SSR-149415 counteracted the internalization process. Moreover, recycling of internalized receptors was observed upon 10-6 M SSR-149415 treatment. Thus SSR-149415/[³H]SSR-149415 are unique tools for studying animal and human V1b R.
