Store-operated calcium entry (SOCE) is essential for many cellular processes. In this study, we investigated modulation of SOCE by tyrosine phosphorylation in rat epididymal basal cells. The intracellular Ca(2+) ([Ca(2+)]i) measurement showed that SOCE occurred in rat epididymal basal cells by pretreating the cells with thapsigargin (Tg), the inhibitor of(More)
In addition to its well established role as a neurotransmitter, extracellular ATP has been considered as a paracrine/autocrine factor, either released from sperm or epithelial cells, in the male reproductive tract and shown to play a versatile role in modulating various reproductive functions. This review summarizes the signal pathways through which ATP(More)
Sodium-hydrogen exchanger as a channel for regulation of intracellular pH might be a crucial modulator of sperm capacitation and motility. Three members of this family have been identified in spermatozoa. A novel protein testis-specific sodium-hydrogen exchanger named mtsNHE was cloned in the present study. The mtsNHE localizing on principle piece of sperm(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 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)
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)
OBJECTIVE To explore the functional role of vacuolar H(+)-ATPase in the pH regulation of epididymal fluid and its effect on sperm motility. DESIGN Experimental study. SETTING Physiology laboratory in a university. ANIMAL(S) Immature male Sprague-Dawley rats. INTERVENTION(S) The H(+)-ATPase inhibitor was applied to the primary culture of epididymal(More)
Several studies have implicated estrogen and the estrogen receptor (ER) in the pathogenesis of benign prostatic hyperplasia (BPH); however, the mechanism underlying this effect remains elusive. In the present study, we demonstrated that estrogen (17β-estradiol, or E2)-induced activation of the G protein-coupled receptor 30 (GPR30) triggered Ca2+ release(More)
