BACKGROUND: Although Traditional Chinese Medicine (TCM) has been widely used in clinical settings, a major challenge that remains in TCM is to evaluate its efficacy scientifically. This randomized controlled trial aims to evaluate the efficacy and safety of berberine in the treatment of patients with polycystic ovary syndrome. In order to improve the transparency and research quality of this clinical trial, we prepared this statistical analysis plan (SAP). METHODS: The trial design, primary and secondary outcomes, and safety outcomes were declared to reduce selection biases in data analysis and result reporting...

The Polycystic Kidney Disease 2 (Pkd2) gene is mutated in autosomal dominant polycystic kidney disease (ADPKD), one of the most common human monogenic disorders. Here, we present the cryo-EM structure of PKD2 in lipid bilayers at 3.0 Å resolution, which establishes PKD2 as a homotetrameric ion channel and provides insight into potential mechanisms for its activation. The PKD2 voltage-sensor domain retains two of four gating charges commonly found in those of voltage-gated ion channels. The PKD2 ion permeation pathway is constricted at the selectivity filter and near the cytoplasmic end of S6, suggesting that two gates regulate ion conduction...

The tuberous sclerosis complex (TSC) proteins are critical negative regulators of the mTORC1 pathway. Germline mutations of TSC1 or TSC2 cause TSC, affecting multiple organs, including the kidney and lung, and causing substantial morbidity and mortality. The mechanisms of organ-specific disease in TSC remain incompletely understood, and the impact of TSC inactivation on mesenchymal lineage cells has not been specifically studied. We deleted Tsc2 specifically in mesoderm-derived mesenchymal cells of multiple organs in mice using the Dermo1-Cre driver...

A primary cilium is present on most eukaryotic cells and represents a specialized organelle dedicated to signal transduction and mechanosensing. Defects in cilia function are the cause for several human diseases called ciliopathies. The serologically defined colon cancer antigen-3 (SDCCAG3) is a recently described novel endosomal protein mainly localized at early and recycling endosomes and interacting with several components of membrane trafficking pathways. Here we describe localization of SDCCAG3 to the basal body of primary cilia...

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by the growth of a number of small cysts on the ovaries which leads to sex hormonal imbalance. Women who are affected by this syndrome suffer from irregular menstrual cycles, decline in their fertility, excessive hair growth, obesity, acne and most importantly cardiac function problems. The vascular endothelial growth factor (VEGF) plays a pivotal role in tissue vascularization in general and in the pathogenesis of many diseases...

Autosomal dominant polycystic kidney disease (ADPKD) is the first genetic cause of end-stage renal disease (ESRD) and the number of these patients who are listed for or receive a kidney transplant (KTx) is continuously increasing over time. Hence, nephrologists are involved not only in the handling of ADPKD patients during the long course of the disease, but also in programming and performing a renal transplant. The handling of all these processes implies the complete awareness of a number of critical points related to the decisions to be taken both before and after the transplant intervention...

Metastatic pulmonary calcification (MPC) is a rare pathological condition consisting of lung calcium salt deposits which commonly occurs in patients affected by chronic kidney disease probably for some abnormalities in calcium and phosphate metabolism. CT represents the technique of choice for detecting MPC findings including ground glass opacities and partially calcified nodules or consolidations. We present a case of MCP in a patient affected by hepato-renal autosomic-dominant polycystic disease; chest CT revealed extensive lobar-segmental parenchymal calcification with a peculiar cauliflower shape which we called "calcified cauliflower" sign...

The objective of the study is to assess the TNF-α levels in PCOS patients and healthy controls. A comprehensive electronic search in Medline, Embase, and the Cochrane Library database was conducted up to July 2016. Random-effects model was used to estimate the standardized mean differences (SMDs) with 95% confidence intervals (CIs). Twenty-nine studies with a total of 1960 participants (1046 PCOS patients and 914 controls) were included in this meta-analysis. The TNF-α levels in PCOS patients were significantly higher than those in controls (random-effects, SMD = 0...

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is characterized by multiple, large renal cysts and impaired kidney function. Although the reason for the development of kidney cysts is unknown, ADPKD is associated with cell cycle arrest and abundant apoptosis of renal tubular epithelial cells. AIMS: We asked whether serum-soluble TNF-related apoptosis-inducing ligand (sTRAIL) might underlie ADPKD. STUDY DESIGN: Case-control study...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common life-threatening monogenic renal disease. ADPKD results from mutations in either of two proteins: polycystin-1 (also known as PC1 or PKD1) or transient receptor potential cation channel, subfamily P, member 2 (TRPP2, also known as polycystin-2, PC2, or PKD2). Each of these proteins is expressed in the primary cilium that extends from many renal epithelial cells. Existing evidence suggests that the cilium can promote renal cystogenesis, while PC1 and TRPP2 counter this cystogenic effect...

OBJECTIVES: Autosomal dominant polycystic kidney disease is the most common hereditary disorder resulting in end-stage renal disease that can affect other organs besides kidneys. Extrarenal involvement may increase mortality and morbidity. Approximately 50% of patients with this disorder require renal transplant. Posttransplant complications have been reported to be equal in these patients versus other recipients. We conducted this study to determine and compare characteristics and outcomes of transplanted patients with this disease versus other recipients at the only transplant center in southern Iran...

European guidelines recommend that patients with hypertension be assessed for asymptomatic organ damage and secondary causes. The authors propose that a single magnetic resonance imaging (MRI) scan can provide comprehensive first-line imaging of patients assessed via a specialist hypertension clinic. A total of 200 patients (56% male, aged 51±15 years, office BP 168±30/96±16 mm Hg) underwent MRI of the heart, kidneys, renal arteries, adrenals and aorta. Comparisons were made with other imaging modalities where available...

CONTEXT: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age. Hyperandrogenism is the central feature of PCOS. Studies on isolated ovarian theca-interstitial cells suggest that resveratrol, a natural polyphenol, reduces androgen production. OBJECTIVE: This study was designed to evaluate endocrine and metabolic effects of resveratrol on PCOS. DESIGN AND SETTING: This was a randomized (1:1) double-blind, placebo-controlled trial that evaluated the effects of resveratrol over a period of 3 months in an academic hospital...

PKHD1 gene mutations are found responsible for autosomal recessive polycystic kidney disease (ARPKD). However, it is inconvenient to detect the mutations by common polymerase chain reaction (PCR) because the open reading frame of PKHD1 is very long. Recently, long-range (LR) PCR is demonstrated to be a more sensitive mutation screening method for PKHD1 by directly sequencing. In this study, the entire PKHD1 coding region was amplified by 29 reactions to avoid the specific PCR amplification of individual exons, which generated the size of 1 to 7 kb products by LR PCR...

Here we describe the case of a HIV-infected patient with polycystic kidney disease and end stage renal diseases not transplantable due to the persistence of a CD4 count <200 notwithstanding a good virological response to highly active antiretroviral therapy and suggest that such limitation to kidney transplantation in such as cases might be bypassed.

OBJECTIVE: The objective of treatment for polycystic liver disease is to reduce the liver volume and reduce or resolve compression symptoms such as abdominal fullness and abdominal pain due to hepatomegaly. Liver cysts are treated internally by puncture and aspiration of the cyst contents or hepatic artery embolization and surgically by cyst fenestration or hepatectomy, but no clear consensus has been reached concerning their selection. We introduced monoethanolamine oleate (EO) sclerotherapy therapy for liver cysts in 1999 and reported its effectiveness...
