A method of uncoupling mitochondria in a subject including administering nanotubes to the subject in a therapeutically effective amount, wherein the nanotubes are self-rectifying is provided. A method of decreasing reactive oxygen species and decreasing detrimental loading of Ca2+ into mitochondria is provided, including administering a pharmaceutically effective amount of nanotubes into the subject. A method of reducing weight, treating cancer, reducing the effects of traumatic brain injury, or reducing the effects of ageing, in a subject including administering a pharmaceutically effective amount of nanotubes into the subject is also provided.

Mitochondrial Ca(2+) uptake via the uniporter is central to cell metabolism, signaling, and survival. Recent studies identified MCU as the uniporter's likely pore and MICU1, an EF-hand protein, as its critical regulator. How this complex decodes dynamic cytoplasmic [Ca(2+)] ([Ca(2+)]c) signals, to tune out small [Ca(2+)]c increases yet permit pulse transmission, remains unknown. We report that loss of MICU1 in mouse liver and cultured cells causes mitochondrial Ca(2+) accumulation during small [Ca(2+)]c elevations but an attenuated response to agonist-induced [Ca(2+)]c pulses. The latter reflects loss of positive cooperativity, likely via the EF-hands. MICU1 faces the intermembrane space and responds to …
