Renal G protein-coupled estrogen receptor 1 regulates the epithelial sodium channel promoting natriuresis to a greater extent in females

This is the authors' abstract. We don't add key points for this paper.

This study identified GPER1 as a sex-specific upstream regulator of ENaC. We found that GPER1 and ENaC were coexpressed in the rat renal tubules in a sex and region-specific manner. Activation of GPER1 inhibited ENaC activity in isolated mouse collecting ducts, whereas deletion of GPER1 from the principal cells caused ENaC hyperactivity to a greater extent in female mice. Our data suggest GPER1 functionally interacts with ENaC in a sex-specific manner to promote natriuresis.
