The omega-3 fatty acid eicosapentaenoic acid accelerates disease progression in a model of amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a progressive fatal neurodegenerative disease characterised by loss of motor neurons that currently has no cure. Omega-3 polyunsaturated fatty acids, such as eicosapentaenoic acid (EPA), have many health benefits including neuroprotective and myoprotective potential. We tested the hypothesis that a high level of dietary EPA could exert beneficial effects in ALS.

Treatment with lithium carbonate does not improve disease progression in two different strains of SOD1 mutant mice.

It has been shown that chronic treatment with lithium carbonate (Li(2)CO(3)) in presymptomatic SOD1G93A transgenic male mice, a model of ALS, was able to remarkably increase their lifespan through the activation of autophagy and the promotion of mitochondriogenesis and neurogenesis. This prompted us to test the lithium effect also in female SOD1G93A mice with two phenotypes of different disease severity. Female SOD1G93A mice of C57BL/6J or 129S2/Sv genetic background were treated daily with Li(2)CO(3) 37 mg/kg (1 mEq/kg) i.
