    Regulator of G protein signaling 12 enhances osteoclastogenesis by suppressing Nrf2-dependent antioxidant proteins to promote the generation of reactive oxygen species

    Andrew Ying Hui Ng et al.
    Rgs12 protein is a novel regulator of the Nrf2 protein by facilitating the proteasomal degradation of the transcription factor during osteoclast differentiation.

    Integrated sensing of host stresses by inhibition of a cytoplasmic two-component system controls M. tuberculosis acute lung infection

    John A Buglino et al.
    M. tuberculosis, the bacterium that causes the disease tuberculosis, uses a signaling system that senses multiple products of the host's immune system to modify gene expression to colonize the lung.

    Alternative splicing of coq-2 controls the levels of rhodoquinone in animals

    June H Tan et al.
    The switch from ubiquinone to rhodoquinone synthesis that is required for parasitic helminths to survive in anaerobic host tissues is due to alternative splicing of polyprenyltransferase COQ-2.

    NADPH oxidase-mediated redox signaling promotes oxidative stress resistance and longevity through memo-1 in C. elegans

    Collin Yvès Ewald et al.
    Genetic analysis reveals NADPH oxidase generated reactive oxygen species as signals to re-establish cellular homeostasis during aging via activating a transcriptional response.

    Processing of motion boundary orientation in macaque V2

    Heng Ma et al.
    Area V2 in macaque monkeys contributes to the perception of the outlines of moving objects and achieves this through a local computation.

    Female-biased upregulation of insulin pathway activity mediates the sex difference in Drosophila body size plasticity

    Jason W Millington et al.
    The ability to adjust body size in response to diet is greater in Drosophila females than males because of a sex difference in the nutrient-dependent regulation of the insulin pathway.

    Temperature-dependent fasciation mutants provide a link between mitochondrial RNA processing and lateral root morphogenesis

    Kurataka Otsuka et al.
    Temperature-dependent fasciation mutants of Arabidopsis unexpectedly connect mitochondrial RNA processing to the control of cell proliferation during lateral root morphogenesis via electron transport chain activity and reactive oxygen species production.

    Nuclear receptor Ftz-f1 promotes follicle maturation and ovulation partly via bHLH/PAS transcription factor Sim

    Elizabeth M Knapp et al.
    Genetic analyses illustrate the novel requirement of Ftz-f1 and Sim in adult Drosophila ovaries for regulating follicle cell differentiation and ovulation that is likely conserved in mammals.

    Homologue replacement in the import motor of the mitochondrial inner membrane of trypanosomes

    Corinne von Känel et al.
    Mitochondrial inner membrane translocation of presequence-containing proteins by the single bifunctional TIM complex of T. brucei requires an non-canonical J domain-containing protein.
