Elevated constitutive expression of Hsp40 chaperone Sis1 reduces TDP-43 aggregation-induced oxidative stress in Ire1 pathway dependent-manner in yeast TDP-43 proteinopathy model of amyotrophic lateral sclerosis.

Abstract excerpt

Oxidative stress is a therapeutic target in TDP-43 proteinopathies like amyotrophic lateral sclerosis (ALS) and FTLD-TDP. TDP-43 over-expression causes oxidative stress in yeast model of ALS. Previously, we developed a red/white color conversion reporter assay using ade1 or ade2 mutant yeast to examine oxidative stress induced by expression of amyloidogenic proteins. Also, a previous study showed that...
