Cowden syndrome (CS), a Mendelian autosomal-dominant disorder, predisposes to breast, thyroid, and other cancers. Germline variations in succinate dehydrogenase genes (SDHx) occur in approximately 10% PTEN mutation-negative CS and CS-like (CSL) individuals (SDH(var+)). We previously showed that SDHx variants result in elevated reactive oxygen species (ROS), disruption of nicotinamide adenine ...

The electrogenic Na(+)-HCO(3)(-) cotransporter NBCe1-B can be regulated by intracellular Mg(2+) (Mg(2+)(i)). We previously reported that under whole-cell voltage-clamp conditions, bovine NBCe1-B (bNBCe1-B) currents heterologously expressed in mammalian cells are strongly inhibited by Mg(2+)(i), and the inhibition is likely mediated by electrostatic interaction and relieved by truncation of the cytosolic ...
