Building on their recent research focusing on a peptide, pNaKtide, designed to block the oxidant amplifying function of the cellular sodium-potassium pump, researchers at Marshall have successfully demonstrated that pNaKtide can attenuate the development of experimental nonalcoholic fatty liver disease (NAFLD) and atherosclerosis.
They did find, however, that when potassium levels are between 4 and 5 mmol/L, the sodium-potassium pump, which moves potassium from the extracellular to the intracellular space, is most active during the first 60 minutes of hemodialysis.
