Enhanced intrarenal renin-angiotensin system (RAS) is implicated in the development and progression of renal injury. To investigate whether angiotensinogen (AGT) expression is involved in glomerular RAS activity and glomerular injury, we examined glomerular AGT expression and its correlation with expression of other RAS components, and levels of glomerular(More)
Axonal transport of tripeptidyl peptidase II, a putative cholecystokinin inactivating serine peptidase, was examined in the proximal, middle, and distal segments of rat sciatic nerves using a double ligation technique. Enzyme activity significantly increased not only in the proximal segment but also in the distal segment 12-72h after ligation, and the(More)
The Na(+)/taurocholate cotransporting polypeptide (NTCP) plays a major role in Na(+)-dependent bile acid uptake into hepatocytes. The purpose of the present study was to establish the heterologous expression of human NTCP (hNTCP) in Xenopus laevis oocytes and to elucidate whether the transport of bile acid via hNTCP is electrogenic using(More)
