    Reactive oxygen species regulate activity-dependent neuronal plasticity in Drosophila

    Matthew CW Oswald et al.
    Reactive oxygen species, previously considered damaging agents linked to pathology, are required for normal neuronal plasticity, including adjustment of synaptic terminal size, maintenance of synaptic physiology and adaptive behavioural responses.

    SIR-2.1 integrates metabolic homeostasis with the reproductive neuromuscular excitability in early aging male Caenorhabditis elegans

    Xiaoyan Guo, L René García
    A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.

    Tumor-promoting function of apoptotic caspases by an amplification loop involving ROS, macrophages and JNK in Drosophila

    Ernesto Pérez et al.
    The oncogenic RasV12 keeps cells mutant for the tumor suppressor scribble in an undead-like condition, which is required for an amplification loop that promotes tumorigenesis.

    Oxidative stress induces stem cell proliferation via TRPA1/RyR-mediated Ca2+ signaling in the Drosophila midgut

    Chiwei Xu et al.
    In response to tissue damage, reactive oxygen species can be sensed by cation channels TRPA1/RyR to cause increases of cytosolic Ca2+ in intestinal stem cells, activating Ras/MAPK activity and stimulating stem cell proliferation in Drosophila.

    Environmental changes in oxygen tension reveal ROS-dependent neurogenesis and regeneration in the adult newt brain

    L Shahul Hameed et al.
    Control of neural stem cells by reactive oxygen species (ROS) provides a link between systemic shifts in oxygen tension and neuronal regeneration, and suggests an evolutionary driving force for the inherent ability of newts to regenerate their brain cells.

    A powerful drug combination strategy targeting glutamine addiction for the treatment of human liver cancer

    Haojie Jin et al.
    Combination of glutaminase inhibitor CB-839 and ASCT2 inhibitor V-9302 showed efficient antitumor effect against glutamine addicted liver cancer cells via glutathione depletion and reactive oxygen species (ROS) induction.

    Photosynthesis: On the art of stealing chloroplasts

    Paulo Cartaxana, Sónia Cruz
    Sea slugs increase the longevity of the chloroplasts they steal from algae by limiting the harmful side-effects of photosynthesis.

    Parkin contributes to synaptic vesicle autophagy in Bassoon-deficient mice

    Sheila Hoffmann-Conaway et al.
    The presynaptic scaffolding protein Bassoon is involved in regulating neurotransmitter release by controlling synaptic vesicle pool size and vesicular protein turnover through increased ubiquitination and Parkin-dependent autophagy.
