Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disorder in which renal tubules become enormously enlarged due to fluid accumulation. Na(+) -K(+) -ATPase was compared in normal and cystic regions of whole kidneys and in confluent primary cultures of microdissected renal tubule and cyst-lining epithelia. Immunostaining with antibodies(More)
Drugs of the disulfonic stilbene class, which inhibit anion transport in the cell membrane in many cell types, have been found to inhibit anion transport and cell growth in Drosophila Kc cells. Cell variants selected by a stepwise selection protocol for the ability to grow in the presence of the disulfonic stilbenes are severalfold resistant to growth(More)
The recent discovery of glial cell line-derived neurotrophic factor (GDNF) identified a novel trophin that selectively increases survival of substantia nigra dopaminergic neurons, which degenerate in Parkinson's disease. Our previous studies indicated that GDNF RNA can be amplified from cultured rat nigral type 1 astrocytes and from rat striatum in vivo,(More)
BACKGROUND Symptoms of cognitive impairment such as poor concentration, memory loss and difficulty with decision making are prevalent in patients with depression, but currently are not specific targets for treatment. However, patients can continue to demonstrate cognitive impairments even when apparently clinically recovered. Drugs that potentiate serotonin(More)
Microglia, the intrinsic immune cells of the central nervous system, are activated in a variety of inflammatory brain diseases in which they play a pathogenetic role. However, mechanisms underlying activation are largely unknown. To begin elucidating molecular mechanisms associated with activation, we characterized the pattern of gene expression in(More)
Drosophila Kc cells use at least two mechanisms for chloride uptake. These transport systems can be distinguished by their kinetic properties and by their differential sensitivity to various drugs. One transport system predominates at [Cl-]o below 30 mM and is greater than fivefold more sensitive to disulfonic stilbenes than the second system. At [Cl-]o(More)
