Peters Pages 1249-1255 It is caused either due to the mutations in the PKD1 or PKD2 gene that encodes polycystin-1 and polycystin-2, respectively. Common mechanisms associated with renal cyst formation include increased cell proliferation, epithelial fluid secretion, and extracellular matrix remodeling. Although cysts derived from renal . A Northwestern Medicine study has uncovered the molecular mechanisms behind the development of autosomal dominant polycystic kidney disease (ADPKD), a common genetic disorder characterized by the growth of numerous cysts in the kidneys.
