The expression of polycystin-1 in the vascular smooth muscle cells (VSMC) of elastic and large distributive arteries suggests that some vascular manifestations of autosomal-dominant polycystic kidney disease (ADPKD) result directly from the genetic defect. Intracranial aneurysms have been reported in PKD2, as well as in PKD1 families. To determine whether the vascular expression of polycystin-2...

زمینه و هدف: بیماری کلیهی پلیکیستیک (polycystic kidney disease=pkd) جزء بیماریهای شایع ارثی  است که در آن قشر و مدولای کلیه با تعداد زیادی کیست اشغال می شود و درنهایت در سنین میانسالی و پس ازآن منجر به esrd می­گردد. نحوه­ی انتقال آن به صورت اتوزومال غالب یا اتوزومال مغلوب است. نوع اتوزومال غالب بیماری شایعترین بیماری ارثی کلیه انسان می باشد که بیشتر در افراد بالغ بروز می کند. در این بیماری ارثی...

Mutations in the PKD2 gene cause autosomal dominant polycystic kidney disease (ADPKD) in humans. The protein encoded by PKD2 has similarity to voltage-sensitive cation channels and TRP channels and was named polycystin-2 (PC2). In agreement with this structural information, expression of PC2 in Xenopus oocytes or reconstitution of human PC2 in planar lipid bilayers produced Ca(2+)-activated cat...

In Xenopus laevis embryos, kidney field specification is dependent on retinoic acid (RA) and coincides with a dramatic increase of Ca transients, but the role of Ca signaling in the kidney field is unknown. Here, we identify TRPP2, a member of the transient receptor potential (TRP) superfamily of channel proteins encoded by the pkd2 gene, as a central component of Ca signaling in the kidney fie...

Generation of laterality depends on a pathway which involves the asymmetrically expressed genes nodal, Ebaf, Leftb, and Pitx2. In mouse, node monocilia are required upstream of the nodal cascade. In chick and frog, gap junctions are essential prior to node/organizer formation. It was hypothesized that differential activity of ion channels gives rise to unidirectional transfer through gap juncti...

Polycystic kidney disease (ADPKD) is a condition with an autosomal dominant mode of inheritance and adult onset. Two forms of the disease, ADPKD1 and ADPKD2, caused by mutations in PKD1 and PKD2, respectively, are very similar, except that ADPKD1 patients run a more severe course. At the cellular level, ADPKD1 was first shown to be recessive, since somatic second hits are perhaps necessary for ...

BACKGROUND Polycystic Kidney Disease is characterized by the formation of large fluid-filled cysts that eventually destroy the renal parenchyma leading to end-stage renal failure. Although remarkable progress has been made in understanding the pathologic mechanism of the disease, the precise orchestration of the early events leading to cyst formation is still unclear. Abnormal cellular prolifer...

Apoptosis, a genetically programmed cell death, allows for homeostasis and tissue remodelling during development of all multi-cellular organisms. Phagocytes swiftly recognize, engulf and digest apoptotic cells. Yet, to date the molecular mechanisms underlying this phagocytic process are still poorly understood. To delineate the molecular mechanisms of apoptotic cell clearance in Drosophila, we ...

Primary cilia are hypothesized to act as a mechanical sensor to detect renal tubular fluid flow. Anomalous structure of primary cilia and/or impairment of increases in intracellular Ca2+ concentration in response to fluid flow are thought to result in renal cyst formation in conditional kif3a knockout, Tg737 and pkd1/pkd2 mutant mice. The mutant inv/inv mouse develops multiple renal cysts like ...

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common hereditary kidney disease. We analysed PKD1 and PKD2, in a large cohort of 440 unrelated Italian patients with ADPKD and 203 relatives by direct sequencing and MLPA. Molecular and detailed phenotypic data have been collected and submitted to the PKD1/PKD2 LOVD database. This is the first large retrospective study in Italian...
