We examined the effects of a P2X7 receptor antagonist and a P2X7 receptor agonist on cyst development in a zebrafish model of polycystic kidney disease in which we knocked down pkd2 by morpholinos.
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.
TRPC6, TRPM6, and TRPP2 have been implicated in hereditary focal segmental glomerulosclerosis (FSGS), hypomagnesemia with secondary hypocalcemia (HSH), and polycystic kidney disease (PKD), respectively.
An initiative of the Polycystic Kidney Disease Foundation, PKDB is a publicly accessible database that aims to streamline the evaluation of PKD1 and PKD2 gene variants detected in samples from those with ADPKD, as well as to assist ongoing clinical and molecular research in the field.
Using the yeast two-hybrid assay, we found that PC2 interacts with the microtubule-dependent motor kinesin-2 subunit KIF3A, a protein involved in polycystic kidney disease.
To use preimplantation genetic diagnosis for achieving a polycystic kidney disease (PKD)-free pregnancy for a couple in which the female partner was affected by PKD but whose PKD1 or PKD2 carrier status was not established.
These data suggest that polycystin-2 functions as a calcium-activated intracellular calcium release channel in vivo and that polycystic kidney disease results from the loss of a regulated intracellular calcium release signalling mechanism.

Other genes related to and interacting with the trp family include the Grc gene, which codes for a growth factor-regulated channel protein, and PKD1/PKD2, involved in polycystic kidney disease.
