Chorein detection for the diagnosis of chorea-acanthocytosis.
نویسندگان
چکیده
Chorea-acanthocytosis (ChAc) is a severe, neurodegenerative disorder that shares clinical features with Huntington's disease and McLeod syndrome. It is caused by mutations in VPS13A, which encodes a large protein called chorein. Using antichorein antisera, we found expression of chorein in all human cells analyzed. However, chorein expression was absent or noticeably reduced in ChAc patient cells, but not McLeod syndrome and Huntington's disease cells. This suggests that loss of chorein expression is a diagnostic feature of ChAc.

Chorein addiction in VPS13A overexpressing rhabdomyosarcoma cells
Chorein encoded by VPS13A (vacuolar protein sorting-associated protein 13A) is defective in chorea-acanthocytosis. Chorein fosters neuronal cell survival, cortical actin polymerization and cell stiffness. In view of its anti-apoptotic effect in neurons, we explored whether chorein is expressed in cancer cells and influences cancer cell survival. RT-PCR was employed to determine transcript level...
متن کاملChorea-acanthocytosis: report of three cases from Iran.
Chorea-acanthocythosis (ChAc) is an inherited neurodegenerative disorder characterized by movement disorders, neuropsychiatric disturbances, neuropathy, myopathy, seizures and acanthocytosis accompanied by an elevated serum creatine kinase (CK) level. Its causative gene (VPS13A) produces chorein which is absent in ChAc patients as evaluated by Western blot assay. We report the first three Irani...
متن کاملChorein Sensitive Dopamine Release from Pheochromocytoma (PC12) Cells.
BACKGROUND Chorein, a protein supporting activation of phosphoinositide 3 kinase (PI3K), participates in the regulation of actin polymerization and cell survival. A loss of function mutation of the chorein encoding gene VPS13A (vacuolar protein sorting-associated protein 13A) leads to chorea-acanthocytosis (ChAc), a neurodegenerative disorder with simultaneous erythrocyte akanthocytosis. In blo...
متن کاملChorein sensitivity of actin polymerization, cell shape and mechanical stiffness of vascular endothelial cells.
BACKGROUND/AIMS Endothelial cell stiffness plays a key role in endothelium-dependent control of vascular tone and arterial blood pressure. Actin polymerization and distribution of microfilaments is essential for mechanical cell stiffness. Chorein, a protein encoded by the VPS13A gene, defective in chorea-acanthocytosis (ChAc), is involved in neuronal cell survival as well as cortical actin poly...
متن کاملHeterozygous Chorein Deficiency in Probable Tau-negative Early-onset Alzheimer Disease
The “amyloid cascade” model of Alzheimer disease (AD) considers b-amyloid accumulation as a primary event that triggers tau hyperphosphorylation, neurofibrillary tangle formation, and ultimately neuron loss. However, this view is challenged by occasional cases without extensive tau pathology (referred to as “tau-negative” or “plaque-only” AD). Originally described by Alzheimer himself, this rar...
