Lung epithelial Na channel subunits are differentially regulated during development and by steroids

S Tchepichev, J Ueda, C Canessa… - … of Physiology-Cell …, 1995 - journals.physiology.org
Because the alpha-subunit of the rat lung epithelial Na channel (rENaC) is not expressed

Developmental regulation of lumenal lung fluid and electrolyte transport

SM Wilson, RE Olver, DV Walters - Respiratory physiology & neurobiology, 2007 - Elsevier
In the fetus, there is a net secretion of liquid (LL) by the lung as a result of active transport of
chloride ions. The rate of secretion and the resulting volume of LL are vital for normal lung …
