Due to alterations in their metabolic activity and decreased mitochondrial efficiency, cancer cells often show increased generation of reactive oxygen species (ROS), but at the same time, to avoid cytotoxic signaling and to facilitate tumorigenic signaling, have mechanism in place that keep ROS in check. This requires signaling molecules that convey increases in oxidative stress to signal to th...
Protein kinase D (PKD) family members are increasingly implicated in multiple normal and abnormal biological functions, including signaling pathways that promote mitogenesis in pancreatic cancer. However, nothing is known about the effects of targeting PKD in pancreatic cancer. Our PKD inhibitor discovery program identified CRT0066101 as a specific inhibitor of all PKD isoforms. The aim of our ...
Renal cysts are clinically and genetically heterogeneous conditions. Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent life-threatening genetic disease and mainly caused by mutations in PKD1. The presence of six PKD1 pseudogenes and tremendous allelic heterogeneity make molecular genetic testing challenging requiring laborious locus-specific amplification. Increasing evi...
Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary renal disease. New data from Paul et al. suggest that mutations in the PKD1 and PKD2 genes may account for all cases of ADPKD. Further improvements in mutation detection methodologies are needed to determine the true relative frequency of PKD1 versus PKD2 as well as to establish the value of mutation type and loc...
Aberrant activation of the mammalian target of rapamycin (mTOR) pathway occurs in polycystic kidney disease (PKD). mTOR inhibitors, such as rapamycin, are highly effective in several rodent models of PKD, but these models result from mutations in genes other than Pkd1 and Pkd2, which are the primary genes responsible for human autosomal dominant PKD. To address this limitation, we tested the ef...
Mutations in two large multi-exon genes, PKD1 and PKD2, cause autosomal dominant polycystic kidney disease (ADPKD). The duplication of PKD1 exons 1-32 as six pseudogenes on chromosome 16, the high level of allelic heterogeneity, and the cost of Sanger sequencing complicate mutation analysis, which can aid diagnostics of ADPKD. We developed and validated a strategy to analyze both the PKD1 and P...
Most cases of autosomal dominant polycystic kidney disease (ADPKD) are the result of mutations in the PKD1 gene. The PKD1 gene codes for a large cell-surface glycoprotein, polycystin-1, of unknown function, which, based on its predicted domain structure, may be involved in protein-protein and protein-carbohydrate interactions. Approximately 30% of polycystin-1 consists of 16 copies of a novel p...
Autosomal dominant polycystic kidney disease (ADPKD) is characterized by formation of multiple fluid-filled cysts that expand over time and destroy renal architecture. The proteins encoded by the PKD1 and PKD2 genes, mutations in which account for nearly all cases of ADPKD, may help guard against cystogenesis. Previously developed mouse models of PKD1 and PKD2 demonstrated an embryonic lethal p...
Clinical trials are underway for the treatment of tuberous sclerosis (TSC)-associated tumours using mTOR inhibitors. Here, we show that many of the earliest renal lesions from Tsc1+/- and Tsc2+/- mice do not exhibit mTOR activation, suggesting that pharmacological targeting of an alternative pathway may be necessary to prevent tumour formation. Patients with TSC often develop renal cysts and th...
Polymorphic DNA markers can now be used for presymptomatic and prenatal diagnosis of the autosomal dominant form of polycystic kidney disease (PKD). A detailed map is known for the chromosomal region around the PKD1 gene on the short arm of chromosome 16. We present here a simple, two step procedure for diagnosis of PKD1 by family studies. Using this approach, at least 92% of random subjects ar...
