Therefore, Ca 2+ directly impacts both energy supply and demand and is essential for cellular energetic homeostasis. Increases in are sensed by and sequestered in mitochondria with flux through the mitochondrial calcium uniporter channel (mtCU) to augment mitochondrial energy output to match cellular demand. cCa 2+ exchange is mediated by numerous stimuli that activate cell surface receptors/channels and intracellular Ca 2+ ( iCa 2+) reservoirs. Here, we provide a historical overview of mitochondrial calcium exchange and comprehensive appraisal of these results in the context of recent literature and discuss possible regulatory pathways of mCa 2+ uptake and mitochondrial bioenergetics.Įlevations in cytosolic Ca 2+ ( cCa 2+) activate multiple energy-consuming cellular processes, ranging from ionic flux to gene regulation, which results in increased energy demand. They posit this is a regulatory feedback mechanism to control ionic homeostasis and mitochondrial bioenergetics with changing fuel availability. 2020) where the authors report that TCA cycle substrate flux regulates the mitochondrial calcium uniporter channel gatekeeper, mitochondrial calcium uptake 1 (MICU1), gene transcription in an early growth response protein 1 (EGR1) dependent fashion.

This hypothesis was recently tested by Nemani et al. While regulatory mechanisms of mitochondrial calcium uptake have been reported, it remains unknown if metabolite flux itself feedback to regulate mitochondrial calcium ( mCa 2+) uptake. This is hypothesized to be an essential pathway of energetic control to meet cellular ATP demand.
