“Whole‐cell voltage‐clamp revealed that estradiol affected the amplitude, decay time, and the voltage dependence of A‐type potassium currents in GnRH neurons.”

“ Estradiol reduced both potassium current in the membrane potential range typically achieved during response to fast synaptic inputs and membrane capacitance.”
“As potassium channels play a crucial role in cell excitability, we hypothesized that 17beta-estradiol caused excitability by modulating potassium flux through the neuronal cell membrane.”
“In the same artery segment, 17beta-estradiol induced a significant decrease in the relative ratio between the repeated contractile response to potassium 30 and 120 mM (100+/-7% vs. 132+/-11%, p<0.05).”

“The data indicate that 17beta-estradiol reduces the renal excretion of sodium and potassium primarily as a consequence of a reduction in food intake and exerts no specific effect on either sodium or potassium metabolism.”
