Journal ArticleDOI
Telomere dysfunction triggers extensive DNA fragmentation and evolution of complex chromosome abnormalities in human malignant tumors
David Gisselsson,Tord Jonson,Åsa Petersén,Bodil Strömbeck,Paola Dal Cin,Mattias Höglund,Felix Mitelman,Fredrik Mertens,Nils Mandahl +8 more
TL;DR: Telomeric dysfunction may trigger chromosomal fragmentation through persistent bridge-breakage events in pancreatic carcinomas and osteosarcomas, leading to a continuous reorganization of the tumor genome.
Journal ArticleDOI
Improving the survival of grafted dopaminergic neurons: a review over current approaches
Patrik Brundin,Jenny Karlsson,Mia Emgård,Gabriele S. Kaminski Schierle,Oskar Hansson,Åsa Petersén,Roger F. Castilho +6 more
TL;DR: Different approaches that reduce cell death and increase survival of grafted neurons, typically by a factor of 2–4 are reviewed; changes in transplantation procedure such as improved media and implantation technique can be beneficial, and calcium channel antagonists such as nimodipine and flunarizine improve nigral graft survival.
Journal ArticleDOI
Orexin loss in Huntington's disease
Åsa Petersén,Joana Gil,Marion L.C. Maat-Schieman,Maria Björkqvist,Heikki Tanila,Inês M. Araújo,Ruben Smith,Natalija Popovic,Nils Wierup,Per Norlén,Jia-Yi Li,Raymund A.C. Roos,Frank Sundler,Hindrik Mulder,Patrik Brundin +14 more
TL;DR: The results show that the loss of orexin is a novel and potentially very important pathology in HD and could be used as a biomarker reflecting neurodegeneration.
Journal ArticleDOI
Transgenic mice expressing a Huntington’s disease mutation are resistant to quinolinic acid-induced striatal excitotoxicity
TL;DR: It is proposed that the presence of exon 1 of the mutant HD gene induces profound changes in striatal neurons that render these cells resistant to excessive NMDA receptor activation.
Journal ArticleDOI
Proteomic profiling of plasma in Huntington's disease reveals neuroinflammatory activation and biomarker candidates.
Annette Dalrymple,Edward J. Wild,Richard Joubert,Kirupa Sathasivam,Maria Björkqvist,Åsa Petersén,Graham S. Jackson,Jeremy D Isaacs,Mark Kristiansen,Gillian P. Bates,Blair R. Leavitt,Geoff Keir,Malcolm Ward,Sarah J. Tabrizi +13 more
TL;DR: Plasma changes with HD progression are revealed and identified proteins demonstrate neuroinflammation in HD and warrant further investigation as possible biomarkers.
