Vascular Expression of Polycystin-2

Vascular expression of polycystin-2.

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...

Polycystin-2 expression is developmentally regulated.

PKD2 encodes a protein of unknown function that is mutated in 15% of autosomal dominant polycystic kidney disease (ADPKD) families. We used polyclonal antisera against PKD2 to examine the pattern of Pkd2 expression in staged mouse embryos. Staining for Pkd2 was documented as early as the 6th embryonic day ( day E6) in the embryonic ectoderm and endoderm. Low-intensity staining is seen in metane...

Polycystin - 1 and Polycystin - 2 Complexes

Polycystin-1 distribution is modulated by polycystin-2 expression in mammalian cells.

Mutations in PKD1 and PKD2, the genes that encode polycystin-1 and polycystin-2 respectively, account for almost all cases of autosomal dominant polycystic kidney disease. Although the polycystins are believed to interact in vivo, the two proteins often display dissimilar patterns and gradients of expression during development. In an effort to understand this apparent discrepancy, we investigat...

Polycystin-2 expression is increased following experimental ischaemic renal injury.

BACKGROUND Mutations in PKD2 account for 15% of patients with autosomal dominant polycystic kidney disease. Expression of the PKD2 protein, polycystin-2, is developmentally regulated, suggesting a major role for this protein during nephrogenesis. However, the regulation of polycystin-2 expression in the adult kidney has not been previously explored. METHODS We have utilized an established mod...
