  1. Herzog E, Bellenchi G, Gras C, Bernard V, Ravassard P, Bedet C, et al. The existence of a second vesicular glutamate transporter specifies subpopulations of glutamatergic neurons. J Neurosci. 2001;21:RC181 pubmed
    ..At the protein level, we could only detect either VGLUT1- or VGLUT2-expressing presynaptic boutons. The existence of two VGLUTs thus defines distinct subsets of glutamatergic neurons. ..
  2. Bayle V, Arrighi J, Creff A, Nespoulous C, Vialaret J, Rossignol M, et al. Arabidopsis thaliana high-affinity phosphate transporters exhibit multiple levels of posttranslational regulation. Plant Cell. 2011;23:1523-35 pubmed publisher
    ..We propose a model for differential trafficking of PHT1 to the plasma membrane or vacuole as a function of phosphate concentration. ..
  3. Duchesne A, Vaiman A, Castille J, Beauvallet C, Gaignard P, Floriot S, et al. Bovine and murine models highlight novel roles for SLC25A46 in mitochondrial dynamics and metabolism, with implications for human and animal health. PLoS Genet. 2017;13:e1006597 pubmed publisher
    ..These data extended the range of phenotypes associated with Slc25a46 dysfunction. Moreover, this Slc25a46 knock-out mouse model should be useful to further elucidate the role of SLC25A46 in mitochondrial dynamics. ..

    ..The work described here offers a first step in the complex genetic dissection of the phosphate transport system in planta. ..
  5. Cailotto F, Bianchi A, Sebillaud S, Venkatesan N, Moulin D, Jouzeau J, et al. Inorganic pyrophosphate generation by transforming growth factor-beta-1 is mainly dependent on ANK induction by Ras/Raf-1/extracellular signal-regulated kinase pathways in chondrocytes. Arthritis Res Ther. 2007;9:R122 pubmed
    ..These data show that TGF-beta1 increases ePPi levels, mainly by the induction of the Ank gene, which requires activation of Ras, Raf-1, ERK, and Ca2+-dependent PKC pathways in chondrocytes. ..
  6. Tatry M, El Kassis E, Lambilliotte R, Corratgé C, van Aarle I, Amenc L, et al. Two differentially regulated phosphate transporters from the symbiotic fungus Hebeloma cylindrosporum and phosphorus acquisition by ectomycorrhizal Pinus pinaster. Plant J. 2009;57:1092-102 pubmed publisher
    ..The expression patterns of HcPT1 and HcPT2 indicate that the two fungal phosphate transporters may be involved in uptake of phosphate from the soil solution under the two soil P availability conditions used...
  7. Lazard M, Blanquet S, Fisicaro P, Labarraque G, Plateau P. Uptake of selenite by Saccharomyces cerevisiae involves the high and low affinity orthophosphate transporters. J Biol Chem. 2010;285:32029-37 pubmed publisher
    ..The properties of phosphate and selenite transport enable us to propose an explanation to the paradoxical increase of selenite toxicity when phosphate concentration in the growth medium is raised above 1 mm. ..
  8. Seguin A, Santos R, Pain D, Dancis A, Camadro J, Lesuisse E. Co-precipitation of phosphate and iron limits mitochondrial phosphate availability in Saccharomyces cerevisiae lacking the yeast frataxin homologue (YFH1). J Biol Chem. 2011;286:6071-9 pubmed publisher
    ..We conclude that in ?yfh1 cells, soluble phosphate is limiting, due to its co-precipitation with iron. ..
  9. Hirsch J, Misson J, Crisp P, David P, Bayle V, Estavillo G, et al. A novel fry1 allele reveals the existence of a mutant phenotype unrelated to 5'->3' exoribonuclease (XRN) activities in Arabidopsis thaliana roots. PLoS ONE. 2011;6:e16724 pubmed publisher
    ..The local up-regulation of PHT1 genes transcription in roots likely results from local depletion of Pi and is independent of the XRNs. ..

    ..Moreover, poplar has developed an alternative Pi uptake pathway distinct from AM plants, allowing ectomycorrhizal poplar to recruit PtPT9 and PtPT12 to cope with limiting Pi concentrations in forest soils. ..
