Featured Study of the Week
Assessing the Usefulness of Activity Indexes of von Willebrand Factor to Predict Therapeutic Response in Hypertrophic Cardiomyopathy
Von Willebrand disease is the most common inherited bleeding disorder worldwide, caused by the missing or defective von Willebrand factor (vWF), a blood-clotting protein. In a recent study published in the American Journal of Cardiology, Mayo Clinic researchers assessed if vWF testing could reflect the natural history of progression in hypertrophic cardiomyopathy and could accurately reflect responses to medical treatment and possibly predict prognosis.
Featured Abstracts
Phosphatidylinositol Phosphate Kinase PIPKIγ and Phosphatase INPP5E Coordinate Initiation of Ciliogenesis
Defective primary cilia are causative to a wide spectrum of human genetic disorders, termed ciliopathies. Although the regulation of ciliogenesis is intensively studied, how it is initiated remains unclear. Mayo Clinic researchers conducted a study to show that type Iγ phosphatidylinositol 4-phosphate (PtdIns(4)P) 5-kinase (PIPKIγ) and inositol polyphosphate-5-phosphatase E (INPP5E), a Joubert syndrome protein, localize to the centrosome and coordinate the initiation of ciliogenesis. PIPKIγ counteracts INPP5E in regulating tau-tubulin kinase-2 (TTBK2) recruitment to the basal body, which promotes the removal of microtubule capping protein CP110 and the subsequent axoneme elongation. The results revealed that PtdIns(4)P homoeostasis, coordinated by PIPKIγ and INPP5E at the centrosome/ciliary base, is vital for ciliogenesis by regulating the CEP164-dependent recruitment of TTBK2. The study was published in Nature Communications.
