Autosomal dominant polycystic kidney disease (ADPKD) is a commonly inherited disorder in humans that causes the formation of fluid-filled renal cysts, often leading to renal failure. PKD1 mutations cause 85% of ADPKD. Feline PKD is autosomal dominant and has clinical presentations similar to humans. PKD affects approximately 38% of Persian cats worldwide, which is approximately 6% of cats, maki...

UNLABELLED Directional beating of ependymal (E) cells' cilia in the walls of the ventricles in the brain is essential for proper CSF flow. E cells display two forms of planar cell polarity (PCP): rotational polarity of individual cilium and translational polarity (asymmetric positioning of cilia in the apical area). The orientation of individual E cells varies according to their location in the...

Mammalian protein kinase D (PKD) isoforms have been proposed to regulate diverse biological processes, including the establishment and maintenance of neuronal polarity. To investigate the function of PKD in neuronal polarization in vivo, we generated PKD knockout (KO) mice. Here, we show that the brain, particularly the hippocampus, of both PKD1 KO and PKD2 KO mice was similar to that of contro...

BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD), a major cause of end-stage renal failure, results from genetic mutation of either polycystin-1 (Pkd1) or polycystin-2 (Pkd2). In order to develop novel therapies to treat the advancement of disease progression, numerous rodent models of different genetic backgrounds are available to study cyst development. METHODS Here, a Pkd1-f...

Genetic mapping of the PKD1 gene in chro-mosomal region 16pl3.3 has depended on the identification of closely linked markers and rare recombinants that suggest the order of loci in relation to meiotic crossover points.'2 This has led to the proposal that the PKD1 gene lies in an approximately 750 kb region close to marker loci D16S84, D16S125, and D16S94, and proximal to the hypervariable probe...

Autosomal dominant polycystic kidney disease (ADPKD), Type I is a common genetic disorder and an important cause of renal failure. The disease is characterized by progressive cyst formation in a variety of organs including the kidney, liver and pancreas. We have previously shown that in the case of PKD1, renal cyst development is likely to require somatic inactivation of the normal allele coupl...
