Dr. Chapple published in the scientific journal Human Molecular Genetics

Dr. Paul Chapple’s group have just published a paper in the scientific journal Human Molecular Genetics that further investigated what is wrong with mitochondria in cells that lack the ARSACS protein sacsin. The research identifies that mitochondria in cells from ARSACS patients have reduced activity of a metabolic pathway that uses enzymes to oxidise nutrients and produce cellular energy. They also express higher levels of genes involved in pathways that deal with mitochondrial damage. A possible mechanism for this decline in mitochondrial health is that a protein called Drp1, which is responsible for the separation of damaged parts of mitochondria from the mitochondrial network, is less efficiently recruited to mitochondria in cells lacking functional sacsin. A reduction in Drp1 mediated fission compromises mitochondrial health in autosomal recessive spastic ataxia of Charlevoix Saguenay.

PHD student does her thesis on ARSACS

Mrs. Emma Duncan a student in Professor Paul Chapple’s laboratory at Queen Mary University of London, who was partly funded by the ARSACS Foundation, successfully passed her PhD examination. Mrs Duncan’s thesis on ‘The Neurodegenerative Disease Autosomal Recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS): Cellular Defects Due To Loss of Sacsin Function’ used cells grown from skin biopsies of Dutch and British ARSACS patients as a model system  to investigate the molecular pathogenesis of the disease. The findings further implicate problems with mitochondria, which act as the cells power plant, and the cytoskeleton, which regulates cellular shape and transport.
