Regulation by PKC isoforms of Na+/H+ exchanger in luminal membrane vesicles isolated from cortical tubules

The present study was designed to determine the Na/H exchanger isoforms present in luminal membrane vesicles (LMV) isolated from rat kidney cortical tubule suspensions, as well as the effects of acute phorbol ester (phorbol myristate acetate, PMA) and angiotensin II (ANG 11) pretreatment of suspensi...

Summary:The present study was designed to determine the Na/H exchanger isoforms present in luminal membrane vesicles (LMV) isolated from rat kidney cortical tubule suspensions, as well as the effects of acute phorbol ester (phorbol myristate acetate, PMA) and angiotensin II (ANG 11) pretreatment of suspensions on NHE activity and protein kinase C (PKC) isoform abundance.
