Polycystin-2 (also called TRPP2), an integral membrane protein mutated in patients with cystic kidney disease, is located in the primary cilium where it is thought to transmit mechanical stimuli into the cell interior. After studying a series of polycystin-2 deletion mutants we identified two amino acids in loop 4 that were essential for the trafficking of(More)
Putrescine, spermidine, and spermine levels were measured in the cortex, caudoputamen, and hippocampus of rats during 30 min of severe forebrain ischemia (induced by occlusion of both carotid and vertebral arteries) and subsequent recirculation. During ischemia, polyamine levels did not change significantly. During postischemic recirculation, however,(More)
Severe forebrain ischemia was produced in rats by occluding both carotid and vertebral arteries. Following 30 min ischemia brains were recirculated for 8 or 24 h. Twelve animals subjected to 8 or 24 h recirculation (n = 6, each group) were given alpha-difluoromethylornithine (DFMO; injected intraperitoneally) immediately before recirculation. At the end of(More)
Podocytes constitute the outer layer of the glomerular filtration barrier, where they form an intricate network of interdigitating foot processes which are connected by slit diaphragms. A hitherto unanswered puzzle concerns the question of whether slit diaphragms are established between foot processes of the same podocyte or between foot processes of(More)
