In autosomal dominant polycystic kidney disease (ADPKD), cyst inflation and continuous enlargement are associated with marked transepithelial ion and fluid secretion into the cyst lumen via cystic fibrosis transmembrane conductance regulator (CFTR). Indeed, the inhibition or degradation of CFTR prevents the fluid accumulation within cysts. The in vivomechanisms bywhich the lack of Polycystin-2 ...

Cytochrome P450 is a family of enzymes that catalyze reactions involved in the metabolism of drugs and other xenobiotics. These enzymes are therefore important in pharmacologic and toxicologic studies, and information on their abundances is of value in the process of scaling in vitro data to in vivo metabolic parameters. A meta-analysis was applied to data on the abundance of human hepatic cyto...

BI 1356 [proposed trade name ONDERO; (R)-8-(3-amino-piperidin-1-yl)-7-but-2-ynyl-3-methyl-1-(4-methyl-quinazolin-2-ylmethyl)-3,7-dihydro-purine-2,6-dione] is a novel dipeptidyl peptidase (DPP)-4 inhibitor under clinical development for the treatment of type 2 diabetes. In this study, we investigated the potency, selectivity, mechanism, and duration of action of BI 1356 in vitro and in vivo and ...

The activity-dependent refinement of neural circuit connectivity during critical periods of brain development is essential for optimized behavioral performance. We hypothesize that this mechanism is defective in fragile X syndrome (FXS), the leading heritable cause of intellectual disability and autism spectrum disorders. Here, we use optogenetic tools in the Drosophila FXS disease model to tes...

It is known that epidermal cells have experienced assault can induce more effective wound healing responses to any subsequent injuries as in innate immune cells. Herein we show wounds a robust effect on distinct stem than previously thought. Of particular relevance, the first activated cell adaptation program only specific lineage. We discovered population lineage produced memory progenitors re...
