    Mitochondrial Ca2+ and membrane potential, an alternative pathway for Interleukin 6 to regulate CD4 cell effector function

    Rui Yang et al.
    Interleukin 6 (IL-6) can mediate pathogenesis of autoimmune diseases through its effects on mitochondrial function.

    Mitochondrial Ca2+ uptake by the voltage-dependent anion channel 2 regulates cardiac rhythmicity

    Hirohito Shimizu et al.
    Enhancing mitochondrial Ca2+ uptake effectively suppresses aberrant Ca2+ induced arrhythmogenic events in zebrafish, mouse and human cardiomyocytes, demonstrating a critical role for mitochondria in the regulation of cardiac rhythmicity.

    Control of cell death/survival balance by the MET dependence receptor

    Leslie Duplaquet et al.
    MET acts as a dependence receptor in vivo by promoting hepatocyte apoptosis, a response induced by a caspase generated fragment able to favor calcium exchange between endoplasmic reticulum and mitochondria.

    Structures reveal gatekeeping of the mitochondrial Ca2+ uniporter by MICU1-MICU2

    Chongyuan Wang et al.
    Cryo-EM structures reveal that MICU1-MICU2 operates like a regulatable toxin to block the pore of the mitochondrial calcium uniporter and confer Ca2+-dependent control.

    IRBIT controls apoptosis by interacting with the Bcl-2 homolog, Bcl2l10, and by promoting ER-mitochondria contact

    Benjamin Bonneau et al.
    IRBIT and the Bcl-2 homolog Bcl2l10 form a complex at the endoplasmic reticulum that controls Ca2+ signaling, however IRBIT turns into an apoptosis facilitator following stress and inhibits anti-apoptotic activity of Bcl2l10.

    Dichotomous role of the human mitochondrial Na+/Ca2+/Li+ exchanger NCLX in colorectal cancer growth and metastasis

    Trayambak Pathak et al.
    Colorectal tumors down-regulate the mitochondrial Na+/Ca2+/Li+ exchanger (NCLX) to alter mitochondrial Ca2+ signaling and initiate transcriptional and metabolic reprogramming that drives tumor chemo-resistance and metastasis.

    Mitochondrial Homeostasis: Auto-regulation in the powerhouse

    Helena M Viola, Livia C Hool
    Mitochondrial flashes have a central role in ensuring that ATP levels remain constant in heart cells.

    The Natural History of Model Organisms: From molecular manipulation of domesticated Chlamydomonas reinhardtii to survival in nature

    Severin Sasso et al.
    Dubbed the 'green yeast', the model alga C. reinhardtii has profoundly advanced many areas of biology, but much remains to be learnt about its life in the wild.

    Point of View: Predictive regulation and human design

    Peter Sterling
    Why does the human regulatory system, which evolution tuned for small satisfactions, now constantly demand 'more'?

    Anti-Cancer Drugs: The mitochondrial paradox

    Sophie L Penman et al.
    A structural motif that is found in two cancer drugs may be responsible for their ability to tackle cancers and for the side-effects caused by the drugs.
