The present study investigated the effects of dopamine on chloride transport across cultured rat caudal epididymal epithelium. The results showed that dopamine induced a biphasic short-circuit current (Isc) in a concentration-dependent manner. The dopamine-induced response consisted of an initial rapid spike followed by a sustained phase. The alpha and beta(More)
Neurotransmitter-controlled Cl- secretions play an important role in maintenance of the epididymal microenvironment for sperm maturation. This study was carried out to investigate the effect of carbachol (CCH) on the cultured rat epididymal epithelium and the signal transduction mechanisms of this response. In normal K-H solution, CCH added basolaterally(More)
BACKGROUND The epithelium lining the epididymis provides an optimal acidic fluid microenvironment in the epididymal tract that enable spermatozoa to complete the maturation process. The present study aims to investigate the functional role of Na(+)/HCO(3)(-) cotransporter in the pH regulation in rat epididymis. METHOD/PRINCIPAL FINDINGS Immunofluorescence(More)
The aim of our present study was to investigate the short-circuit current response to carbachol in cultured rat cauda epididymal epithelia and the signal transduction mechanisms involved. Carbachol added basolaterally induced a concentration-dependent increase in short-circuit current (Isc) across the epididymal epithelium consisting of a rapidly rising(More)
