Fig. 10. Schematic diagram showing how estrogen downregulates ENaC by promoting derlin-1 expression and AMPK activation.

Estrogen treatment decreased ENaC expression through two degradation pathways: in the first, upregulation of derlin-1 by estrogen promoted ENaC proteasome-related degradation, while in the second, activation of AMPK by estrogen induced ENaC internalization from the cell membrane and increased ENaC/Nedd4-2 interaction
