In spinocerebellar ataxia type 17 (SCA17), the expansion of a translated CAG repeat in the TATA box binding protein (TBP) gene results in a long polyglutamine (polyQ) tract in the TBP protein, leading to intracellular accumulation of aggregated TBP and cell death. The molecular chaperones act in preventing protein aggregation to ameliorate downstream(More)
The integration and control of systemic immune responses depends on the regulated trafficking of T-lymphocytes. This study elucidates how various exercises regimens with/without hypoxia affect phenotypic characteristics of T-lymphocyte subsets in blood. Fifty sedentary males were randomly divided into five groups. Each group (n=10) received one of five(More)
Spinocerebellar ataxias (SCAs), caused by expanded CAG repeats encoding a long polyglutamine (polyQ) tract in the respective proteins, are characterized by the accumulation of intranuclear and cytoplasmic misfolded polyQ aggregation that leads to cell death. Suppression of aggregate formation can inhibit a wide range of downstream pathogenic events and is(More)
Spinocerebellar ataxia (SCA) types 1, 2, 3, 6, 7, and 17 as well as Huntington's disease are a group of neurodegenerative disorders caused by expanded CAG repeats encoding a long polyglutamine (polyQ) tract in the respective proteins. Evidence has shown that the accumulation of intranuclear and cytoplasmic misfolded polyQ proteins leads to apoptosis and(More)
OBJECTIVE This study sought to determine the psychometric properties for the Loewenstein Occupational Therapy Cognitive Assessment-Second Edition (LOTCA-II) in a population of persons with schizophrenia. METHOD Sixty-four participants with schizophrenia were administered the LOTCA-II at baseline, and 43 of these were randomly selected to undertake four(More)
Trehalose, a chemical chaperone and mTOR-independent autophagy enhancer, has shown promise in models of Huntington's disease, Parkinson's disease and tauopathies. In this study, two trehalase analogs, lactulose and melibiose, were examined for their potentials in spinocerebellar ataxia treatment. Using a SCA3 ATXN3/Q75-GFP cell model, we found that the(More)
The unique property of trehalose encourages its pharmaceutical application in aggregation-mediated neurodegenerative disorders, including Alzheimer's, Parkinson's, and many polyglutamine (polyQ)-mediated diseases. However, trehalose is digested into glucose by trehalase and which reduced its efficacy in the disease target tissues. Therefore, searching(More)
In polyglutamine (polyQ)-mediated disorders, the expansion of translated CAG repeats in the disease genes result in long polyQ tracts in their respective proteins, leading to intracellular accumulation of aggregated polyQ proteins, production of reactive oxygen species, and cell death. The molecular chaperones act in preventing protein misfolding and(More)
Genetic variants of leucine-rich repeat kinase 2 (LRRK2) were reported to alter the risk for Parkinson's disease (PD). However, the genetic spectrum of LRRK2 variants has not been clearly disclosed yet in Taiwanese population. Herein, we sequenced LRRK2 coding region in 70 Taiwanese early onset PD patients (age at onset ≤ 50), and found six amino(More)
