Oestrogen (E) and progestogen (P) exert regulatory effects on the epithelial Na+ channel
(ENaC) in the kidneys and the colon. However, the effects of E and P on the ENaC and on …

Lung epithelial ion transport promotes salt and water movement across the fetal and
neonatal lung epithelium. The mechanism is dependent on basolateral membrane Na-K …

Publisher Summary This chapter discusses a study on induction of epithelial sodium
channel (ENaC) expression and sodium transport in distal lung epithelia by oxygen. The …

The Na+ pump, Na+-K+-ATPase, along with the Na+ channel is essential for the removal of
alveolar solute and fluid perinatally. Because Na+-pump mRNA and activity increase before …

There is considerable interest in identifying the basic mechanisms by which dexamethasone
alters ion transport across the adult alveolar epithelium. Herein, we incubated synchronized …

The perforated patch recording technique was used to investigate the effects of
dexamethasone (0.2 μm, 24–30 h), a synthetic glucocorticoid, on membrane conductance in …

We have studied factors that potentially modulate the expression of mRNA coding for
subunits of the amiloride‐sensitive sodium channel, αENaC and βENaC, in lungs of …

Publisher Summary The chapter presents a study on catecholamine regulation of amiloride-
sensitive sodium ion (Na+) transport in the fetal rat alveolar epithelium. The chapter …

OBJECTIVE. In the newborn infant, removal of fetal lung liquid from the airways depends on
ion transport through the airway epithelium. The epithelial sodium channel is considered …

Isolated rat fetal distal lung epithelial (FDLE) cells were cultured (≈ 48 h) on permeable
supports in medium devoid of hormones and growth factors whilst PO2 was maintained at …
