Lipophilic antioxidants in neurodegenerative diseases

Publication date: October 2018Source: Clinica Chimica Acta, Volume 485Author(s): Kuo-Hsuan Chang, Mei-Ling Cheng, Mu-Chun Chiang, Chiung-Mei ChenAbstractOxidative stress is commonly involved in the pathogenesis of various neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease and amyotrophic lateral sclerosis. Therefore, lipophilic antioxidants, such as vitamin A, carotinoids, vitamin E, coenzyme Q10, docosahexaenoic acid and eicosapentaenoic acid, have received increasing attention as therapeutic and preventive intervention for neurodegenerative diseases. Although difficulties exist with clinical studies due to the nature of the long-standing progression of neurodegenerative diseases, findings in cell and animal models, as well as biomarker studies have implied a relationship between lipophilic antioxidants and neurodegeneration. By reviewing current findings and their implication in neurodegenerative diseases, we conclude that although none of these lipophilic antioxidants have yet provided clear-cut clinical evidence toward beneficial effects in neurodegenerative diseases, they could demonstrate neuroprotection in cellular and/or animal studies. Results from future multidisciplinary studies with optimization of factors including drug dosage, delivery route and chemical structure may provide us with novel treatments for neurodegenerative diseases using lipophilic antioxidants.

We evaluated the clinical effects of a unique telephone call system that automatically called participants at their desired times once a week for 3 months. In total, 104 neurological disease patients and caregivers were evaluated by the geriatric depression scale, apathy ...

Authors: Walker LC, Meadows MR, Du Y, March LK, Jones JK Abstract BACKGROUND: Amyotrophic lateral sclerosis (ALS) is devastating, leading to paralysis and death. Disease onset begins pre-symptomatically through spinal motor neuron (MN) axon die-back from musculature at ∼47 days of age in the mutant superoxide dismutase 1 (mSOD1G93A) transgenic ALS mouse model. This period may be optimal to assess potential therapies. We previously demonstrated that post-symptomatic adipose-derived stem cell conditioned medium (ASC-CM) treatment is neuroprotective in mSOD1G93A mice. We hypothesized that early disease onset treat...

(VIB (the Flanders Institute for Biotechnology)) The mutated and aggregated protein FUS is implicated in two neurodegenerative diseases: amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Using a newly developed fruit fly model, researchers led by prof. Ludo Van Den Bosch (VIB-KU Leuven) have zoomed in on the protein structure of FUS to gain more insight into how it causes neuronal toxicity and disease.

Abnormalities in nucleic acid processing are associated with the development of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Mutations inMatrin 3 (MATR3), a poorly understood DNA- and RNA-binding protein, cause familial ALS/FTD, and MATR3 pathology is a feature of sporadic disease, suggesting that MATR3 dysfunction is integrally linked to ALS pathogenesis. Using a rat primary neuron model to assess MATR3-mediated toxicity, we noted that neurons were bidirectionally vulnerable to MATR3 levels, with pathogenic MATR3 mutants displaying enhanced toxicity. MATR3 ’s zinc finger domains partially m...
