Abstract Objectives: Mitochondrial Ca2+ uniporter (MCU) provides a Ca2+ influx pathway from the cytosol into the mitochondrial matrix and a moderate mitochondrial Ca2+ rise stimulates ATP production and cell growth. MCU is highly expressed in various cancer cells including breast cancer cells, thereby increasing the capacity of mitochondrial Ca2+ uptake, ATP production, and cancer cell proliferation. The objective of this study was to examine MCU inhibition as an anti-cancer mechanism. Methods: The effects of MCU-i4, a newly developed MCU inhibitor, on cell viability, apoptosis, cytosolic Ca2+, mitochondrial Ca2+ and potential, glycolytic rate, generation of ATP, and reactive oxygen species,… More >
