Background: Skull development is a tightly regulated process that occurs along the osteogenic interfaces of the cranial sutures that allow rapid bone formation at the edges of the bone fronts. Premature closure of cranial sutures can result in pathological conditions such as Craniosynostosis. The mechanosensory proteins Polycystin 1 (PC1) and 2 (PC2) have been shown to regulate skeletal development and potentially suture formation.Aim: The aim of study w...

Osteosarcoma is the most common primary bone-derived tumor. However, the pathogenic molecular mechanism(s) underpinning osteosarcoma development and metastasis remain elusive. The polycystins PC1 (polycystin-1; encoded by PKD1) and PC2 (polycystin-2) are central players in mechanotransduction, a process that can influence all steps of the invasion/metastasis cascade. Recent studies from our laboratory provided, for the first time, a direct link between mechanosensing polycysti...
