Polycystic kidney disease (PKD) is a major cause of end-stage renal disease. The disease mechanisms are not well understood and the pathogenesis toward renal failure remains elusive. In this study, we present the first RNASeq analysis of a Pkd1-mutant mouse model in a combined meta-analysis with other published PKD expression profiles. We introduce the PKD Signature, a set of 1,515 genes that a...

There are no proven, effective therapies for polycystic kidney disease (PKD) or polycystic liver disease (PLD). We enrolled 42 patients with severe PLD resulting from autosomal dominant PKD (ADPKD) or autosomal dominant PLD (ADPLD) in a randomized, double-blind, placebo-controlled trial of octreotide, a long-acting somatostatin analogue. We randomly assigned 42 patients in a 2:1 ratio to octreo...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common life-threatening hereditary disease in the USA resulting in chronic kidney disease and the need for dialysis and transplantation. Approximately 85% of cases of ADPKD are caused by a mutation in the Pkd1 gene that encodes polycystin-1, a large membrane receptor. The Pkd1 gene mutation results in abnormal proliferation in tub...

BACKGROUND The mTOR pathway, which consists of mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2), is activated in polycystic kidney disease (PKD) kidneys. Sirolimus and everolimus indirectly bind and inhibit mTORC1. A novel group of drugs, the mTOR kinase inhibitors, directly bind to mTOR kinase, thus inhibiting both mTORC1 and 2. The aim of the study was to determine the therapeutic effect o...

BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is a progressive genetic disorder characterized by the development of numerous kidney cysts that result in kidney failure. Little is known regarding the key patient characteristics and utilization of healthcare resources for ADPKD patients along the continuum of disease progression. This observational study was designed to describe...

Polycystic kidney disease (PKD) is a genetic disorder characterized by aberrant renal epithelial cell proliferation and formation progressive growth of numerous fluid-filled cysts within the kidneys. Previously, we showed that there elevated Notch signaling compared to normal cells contributes cystic cells. Quinomycin A, bis-intercalator peptide, has previously been shown target pathway inhibit...

Cardiovascular complications remain the major problems contributing to morbidity and mortality in patients with polycystic kidney disease (PKD). Therefore, the authors hypothesized that atrial fibrillation (AF) is closely associated with PKD. The authors conducted a nationwide population-based cohort study to investigate the risk of AF in patients with PKD. Using data from inpatient claims, the...

Autosomal dominant polycystic kidney disease (ADPKD) strikes 1 in 1000 individuals and often results in end-stage renal failure. Mutations in either PKD1 or PKD2 account for 95% of all cases [1-3]. It has recently been demonstrated that polycystin-1 and polycystin-2 (encoded by PKD1 and PKD2, respectively) assemble to form a cation channel in vitro [4]. Here we determine that the Caenorhabditis...

Polycystic kidney diseases (PKD) are inherited as autosomal dominant (ADPKD) or autosomal recessive (ARPKD) traits and are characterized by progressive enlargement of renal cysts. Aberrant cell proliferation is a key feature in the progression of PKD. Cux1 is a homeobox gene that is related to Drosophila cut and is the murine homolog of human CDP (CCAAT Displacement Protein). Cux1 represses the...

Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common genetic kidney disorders. Thiazolidinediones (TZDs) are anti-diabetic drugs that have been shown to suppress polycystic kidney diseases (PKD) development. However, their underlying mechanism of action remains largely unknown. Insulin-like growth factor-1 (IGF-1) expression increases with the progression of cystic les...
