Abstract: Disclosed are methods for identifying compounds that modulate huntingtin mediated impairment of protein degradation pathways. Compounds identified by such screens can be used as candidate drugs for the treatment of prevention of polyglutamine diseases such as Huntington's Disease.

Abstract: Methods of screening candidate agents to identify lead compounds for the development of therapeutic agents for the treatment of a neurodegenerative disease, such as Huntington's Disease and Parkinson's Disease and methods for identifying a mutation in, or changes in expression of, a gene associated with neurodegenerative disease, such as Huntington's Disease and Parkinson's Disease, are provided.

Abstract: Disclosed are yeast ectopically expressing abnormally processed proteins and methods of screening to identify compounds that modulate the function of such abnormally processed proteins in yeast. Compounds identified by such screens can be used to treat or prevent diseases associated with abnormally processed proteins or protein misfolding. Such diseases include Parkinson's Disease, Parkinson's Disease with accompanying dementia, Lewy body dementia, Alzheimer's disease with Parkinsonism, and multiple system atrophy.

Abstract: The present invention provides a novel class of withanolides that have been isolated from W. somnifera under aeroponic conditions or produced semi-synthetically from withanolide natural products. The invention also provides pharmaceutical compositions thereof and methods for using the same in proliferative diseases, neurodegenerative diseases, autoimmune, and inflammatory diseases.

Abstract: Disclosed are genes that, when overexpressed in cells expressing alpha-synuclein, either suppress or enhance alpha-synuclein mediated cellular toxicity. Compounds that modulate expression of these genes or activity of the encoded proteins can be used to inhibit alpha-synuclein mediated toxicity and used to treat or prevent synucleinopathies such as Parkinson's disease. Also disclosed are methods of identifying inhibitors of alpha-synuclein mediated toxicity.

Abstract: Disclosed are yeast cells expressing TAR DNA-binding protein 43 (TDP-43) and methods of screening yeast cells to identify compounds that prevent or suppress TDP-43-induced toxicity, compounds that inhibit the formation or maintenance of cytoplasmic inclusions of TDP-43, genetic suppressors or enhancers of TDP-43-induced toxicity, and genetic suppressors or enhancers of the formation or maintenance of cytoplasmic inclusions of TDP-43. Compounds identified by such screens can be used to treat or prevent TDP-43 proteinopathies such as frontotemporal lobar degeneration or amyotrophic lateral sclerosis.

Abstract: Compounds and compositions are provided for treatment or amelioration of one or more symptoms of ?-synuclein toxicity, ?-synuclein mediated diseases or diseases in which ?-synuclein fibrils are a symptom or cause of the disease.

Abstract: Disclosed are genes that, when overexpressed in cells expressing alpha-synuclein, either suppress or enhance alpha-synuclein mediated cellular toxicity. Compounds that modulate expression of these genes or activity of the encoded proteins can be used to inhibit alpha-synuclein mediated toxicity and used to treat or prevent synucleinopathies such as Parkinson's disease.

Abstract: Disclosed are compositions and methods for modulating expression of genes that function at the step of ER of Golgi trafficking. Compounds that modulate expression of these genes of activity of the encoded proteins can be used to inhibit alpha-synuclein mediated toxicity and used to threat of prevent synucleinopathies such as Parkinson's disease. Also disclosed are methods of identifying inhibitors of alpha-synuclein mediated toxicity.

Abstract: Compounds and compositions are provided for treatment or amelioration of one or more symptoms of ?-synuclein toxicity, ?-synuclein mediated diseases or diseases in which ?-synuclein fibrils are a symptom or cause of the disease. In one embodiment, the compounds for use in the compositions and methods are heteroaryl acylguanidines, heteroarylhydrazones, dihy-dropyridones, heteroaryl and aryl styryl ketones, and heteroarylpyrazoles.

Abstract: Disclosed are compounds and conditions that either suppress or enhance toxicity in yeast cells expressing alpha synuclein or huntingtin. These compounds and conditions can be used in the development of compositions that suppress toxicity, fibril formation, and/or diseases mediated at least in part by alpha synuclein or huntingtin.

Abstract: The invention relates to methods of identifying, detecting or designing drugs that inhibit the formation of or accumulation of PrP, PrPSc or both in cells; to drugs that inhibit the formation of or accumulation of PrP, PrPSc or both in cells; to methods of preventing or reducing the adverse effects of PrP, PrPSc or both in humans; and to transgenic nonhuman mammals, such as transgenic mice, that ectopically express PrP.
