Abstract: Polynucleotide molecules and the proteins encoded by the molecules, diagnostic and treatment methods for neurological disorders characterized by protein aggregation are provided. Genes are described herein that affect the misfolding of, and subsequent aggregation of, aggregation-prone proteins such as alpha-synuclein and have implications for the diagnosis and treatment of neurological diseases related to protein aggregation such as Parkinson's disease. Knockdown of expression of the genes described herein using RNAi results in alpha-synuclein protein aggregation in a C. elegans model of protein aggregation. Dopaminergic neuroprotection after overexpression of alpha-synuclein may also be provided by overexpression of proteins.

Abstract: Methods are provided for preventing neurodegeneration and neuronal loss by administering compositions comprising small molecule compounds with the effect of preventing neurodegeneration and neuronal loss. In one aspect of the invention, the methods and compositions are also useful for treating neurodegenerative diseases. Small molecule compounds provide an important treatment option because of their stability, ease of use in both manufacture and formulation, ease of administration, and patient compliance. The small molecule compound compositions of the present invention may include topoisomerase II inhibitors, bacterial transpeptidase inhibitors, calcium channel antagonists, cyclooxygenase inhibitors, folic acid synthesis inhibitors, or sodium channel blockers and functional analogues thereof that have an effect on neurodegeneration.

Abstract: The invention relates to polynucleotides comprising polynucleotide sequences corresponding to the tor-1, tor-2, ooc-5, DYT1, and DYT2 genes and parts thereof that encode polypeptide sequences and parts thereof possessing varying degrees of torsin activity, and methods of screening and amplifying polynucleotides encoding polypeptide sequences which encode polypeptides having varying degrees of TOR-1, TOR2, OOC-5 TOR-A, and TOR-B activity. Further, the invention relates to methods of reducing protein aggregation, methods of treating diseases that are caused by protein aggregation, methods of screening potential protein-aggregation-reducing products, methods of screening potential therapeutics of diseases caused by protein aggregation, and pharmaceuticals, therapeutics, and kits comprising polynucleotide sequences corresponding to the tor-1, tor-2, ooc-5, DYT1, and DYT2 genes and/or polypeptides having torsin activity.
