Abstract
Background: Mitochondrial Ca2+ uptake affects energy metabolism and insulin secretion. Results: Knockdown of mitochondrial Ca2+ uniporter decreases respiratory chain activity and mitochondrial pH gradient generation. Conclusion: Mitochondrial Ca2+ uptake via uniporter is essential for oxidative phosphorylation and metabolism-secretion coupling. Significance: The present study identifies mechanisms of action and bioenergetic consequences of mitochondrial Ca2+ transporters in insulin-releasing cells.
