  1. Veenstra J. The power of next-generation sequencing as illustrated by the neuropeptidome of the crayfish Procambarus clarkii. Gen Comp Endocrinol. 2015;224:84-95 pubmed publisher
    ..The ovary also appears to contain significant numbers of transcripts encoding pigment dispersing hormones, CNMamide as well as glycoprotein B5, but not glycoprotein A2. ..
  2. Veenstra J. Two Lys-vasopressin-like peptides, EFLamide, and other phasmid neuropeptides. Gen Comp Endocrinol. 2018;: pubmed publisher
    ..Finally, both species have genes coding EFLamide and its GPCR; in phasmids these genes codes for one (Clitarchus) or two (Timema) EFLamide paracopies. ..
  3. Veenstra J. Neuropeptide evolution: Chelicerate neurohormone and neuropeptide genes may reflect one or more whole genome duplications. Gen Comp Endocrinol. 2016;229:41-55 pubmed publisher
    ..As the large majority of these are probably not due to local gene duplications, is plausible that they reflect the effects of one or more ancient whole genome duplications. ..
  4. Veenstra J. Allatostatins C, double C and triple C, the result of a local gene triplication in an ancestral arthropod. Gen Comp Endocrinol. 2016;230-231:153-7 pubmed publisher
    ..In some arthropod species two or even all three genes can still be found closely associated in the genome and are present on the same scaffold showing that a local amplification was at the origin of these genes. ..
  5. Veenstra J, Ida T. More Drosophila enteroendocrine peptides: Orcokinin B and the CCHamides 1 and 2. Cell Tissue Res. 2014;357:607-21 pubmed publisher
  6. Sellami A, Veenstra J. SIFamide acts on fruitless neurons to modulate sexual behavior in Drosophila melanogaster. Peptides. 2015;74:50-6 pubmed publisher
    ..We next used this transgene to localize neurons that express the SIFamide receptor. Such neurons are ubiquitously present in the central nervous and we also found two neurons in the uterus that project into the central nervous system. ..
  7. Veenstra J. Neuropeptide Evolution: Chelicerate Neurohormone and Neuropeptide Genes may reflect one or more whole genome duplications. Gen Comp Endocrinol. 2016;: pubmed publisher
    ..As the large majority of these are probably not due to local gene duplications, is not impossible that they reflect the effects of one or more ancient whole genome duplications. ..
  8. Veenstra J, Khammassi H. Rudimentary expression of RYamide in Drosophila melanogaster relative to other Drosophila species points to a functional decline of this neuropeptide gene. Insect Biochem Mol Biol. 2017;83:68-79 pubmed publisher
    ..virilis and D. pseudoobscura, but only two adult abdominal neurons in D. melanogaster. Those two neurons project to and innervate the rectal papillae, suggesting that RYamides may be involved in the regulation of water homeostasis. ..
