Mitochondrial TCA cycle intermediates regulate body fluid and acid-base balance.
Los Angeles, United States. In J Clin Invest, 2013
In this issue of the JCI, Tokonami et al. report on the function of an exciting new paracrine mediator, the mitochondrial the citric acid(TCA) cycle intermediate α-ketoglutarate (αKG), which via its OXGR1 receptor plays an unexpected, nontraditional role in the adaptive regulation of renal HCO(3⁻) secretion and salt reabsorption.
