    Essential and dual effects of Notch activity on a natural transdifferentiation event by Thomas Daniele, Jeanne Cury, Marie-Charlotte Morin, Arnaud Ahier, Davide Isaia, Sophie Jarriault

    Published 2025-01-01
    “…We find that Notch signalling plays a key role to promote natural transdifferentiation in C. elegans hermaphrodites. Endogenous Notch signalling endows a cell with the competence to transdifferentiate by promoting plasticity factors expression (hlh-16/Olig and sem-4/Sall). …”

    The IclR-family transcriptional regulator XyrR controls flotation, motility, antibiotic production and virulence in Serratia sp. ATCC 39006 by Carlo Miguel Castro Sandoval, Carlo Miguel Castro Sandoval, George P. C. Salmond

    Published 2025-01-01
    “…Furthermore, the mutant also showed increased swimming and swarming motilities but exhibited attenuated virulence in planta and ability to kill the nematode C. elegans. Using differential expression analysis of the intracellular proteomes of the wild type and iclR mutant, we confirmed that the mutation negatively impacted expression of the corresponding GV, carbapenem and prodigiosin gene clusters. …”

    Published 2025-01-01
    “…Here, using Caenorhabditis elegans as a model system, combined with the optogenetic tool KillerRed to spatially and temporally control ROS generation, we identify a previously uncharacterized gene, oxidative stress protective 1 (osp-1), that protects C. elegans neurons from oxidative damage. Using rodent and human cell cultures, we also show that the protective effect of OSP-1 extends to mammalian cells. …”

    Compilation and functional classification of telomere length-associated genes in humans and other animal species by E. V. Ignatieva, N. S. Yudin, D. M. Larkin

    Published 2023-06-01
    “…Among them were two orthologous genes encoding a shelterin protein (POT1 in humans and pot-2 in C. elegans). Functional analysis has shown that telomere length can be influenced by genetic variants in the genes encoding: (1) structural components of telomerase; (2) the protein components of telomeric regions (shelterin and CST complexes); (3) the proteins involved in telomerase biogenesis and regulating its activity; (4) the proteins that regulate the functional activity of the shelterin components; (5) the proteins involved in telomere replication and/or capping; (6) the proteins involved in the alternative telomere lengthening; (7) the proteins that respond to DNA damage and are responsible for DNA repair; (8) RNA-exosome components. …”

    <i>Weizmannia coagulans</i> BC99 Attenuates Oxidative Stress Induced by Acute Alcoholic Liver Injury via Nrf2/SKN-1 Pathway and Liver Metabolism Regulation by Ying Wu, Cheng Li, Yinyin Gao, Jie Zhang, Yao Dong, Lina Zhao, Yuwan Li, Shaobin Gu

    Published 2025-01-01
    “…Additionally, BC99 treatment elevated glutamate and aspartate levels while reducing glycerate and glucose, which collectively increased glutathione levels and mitigated oxidative stress triggered by glucose metabolism disorders. In C. elegans, BC99 reduced excessive ROS by upregulating <i>Nrf2</i>/<i>skn-1</i>, <i>daf-16</i>, and their downstream antioxidant genes, consequently alleviating the biotoxicity associated with alcohol-induced oxidative damage. …”
