    Large-scale deorphanization of Nematostella vectensis neuropeptide G protein-coupled receptors supports the independent expansion of bilaterian and cnidarian peptidergic systems

    Daniel Thiel, Luis Alfonso Yañez Guerra ... Gáspár Jékely
    The identification of 31 neuropeptide GPCRs in the sea anemone Nematostella vectensis provides a rich resource to study peptidergic signaling in cnidarians and suggests that cnidarian and bilaterian peptidergic systems diversified independent from each other from a few ancestral systems.

    Luqin-like RYamide peptides regulate food-evoked responses in C. elegans

    Hayao Ohno, Morikatsu Yoshida ... Yuichi Iino
    Identification and functional characterization of C. elegans luqin-like arginine-tyrosine-NH2 (RYamide) peptides reveal their critical role in feeding-related processes.

    The RFamide receptor DMSR-1 regulates stress-induced sleep in C. elegans

    Michael J Iannacone, Isabel Beets ... David M Raizen
    During sickness, sleep is induced by neuropeptides, which contain an amidated arginine-phenylalanine motif, acting in a neuroendocrine fashion on a G-protein coupled receptor called DMSR-1.

    The rise and fall of the Phytophthora infestans lineage that triggered the Irish potato famine

    Kentaro Yoshida, Verena J Schuenemann ... Hernán A Burbano
    The strain of Phytophthora infestans that caused the Great Famine in the late 1840s was caused by a single genotype that is distinct from, but closely related to, the most prevalent modern genotype.

    MITF reprograms the extracellular matrix and focal adhesion in melanoma

    Ramile Dilshat, Valerie Fock ... Eirikur Steingrimsson
    Analysis of knockout and knockdown melanoma cells and TCGA melanoma data shows that the microphthalmia-associated transcription factor (MITF) is a major repressor of extracellular matrix (ECM) and focal adhesion genes.

    An effector of the Irish potato famine pathogen antagonizes a host autophagy cargo receptor

    Yasin F Dagdas, Khaoula Belhaj ... Tolga O Bozkurt
    A plant pathogen effector evolved a short linear motif to subvert autophagic defenses by antagonising a host cargo receptor.

    CRISPR knockouts reveal an endogenous role for ancient neuropeptides in regulating developmental timing in a sea anemone

    Nagayasu Nakanishi, Mark Q Martindale
    Analysis of the endogenous function of deeply conserved neuropeptides in sea anemones sheds light on a primitive role of nervous systems in modulating developmental timing.

    Genetic and neuronal regulation of sleep by neuropeptide VF

    Daniel A Lee, Andrey Andreev ... David A Prober
    Genetic experiments in zebrafish identify neuropeptide VF (NPVF) signaling and NPVF-expressing neurons as a novel vertebrate hypothalamic sleep-promoting system that is functionally conserved with invertebrates.

    A genetic variant of fatty acid amide hydrolase (FAAH) exacerbates hormone-mediated orexigenic feeding in mice

    Georgia Balsevich, Gavin N Petrie ... Matthew N Hill
    A genetic knock-in mouse model reveals that the endocrine state governs the effect of the common fatty acid amide hydrolase C385A variant on body weight through a hypothalamic-mediated mechanism.

    Echinoderms provide missing link in the evolution of PrRP/sNPF-type neuropeptide signalling

    Luis Alfonso Yañez-Guerra, Xingxing Zhong ... Maurice R Elphick
    Discovery of a novel neuropeptide signalling system in a deuterostome invertebrate reveals the evolutionary origin of prolactin-releasing peptide and its relationship with neuropeptides in protostome invertebrates.
