MICU1 drives glycolysis and chemoresistance in ovarian cancer.

The mitochondrial uniporter MICU1 regulates mitochondrial Ca2+ uptake. Here, the authors show that MICU1 is upregulated in ovarian cancer and confers resistance to cisplatin-induced apoptosis through a Ca2+-mediated regulation of pyruvate dehydrogenase activity that results in increased glycolysis.
