Discovery of novel molecules that regulate pathology of spinocerebellar ataxia.

By using systems biology, we newly identified two DNA damage repair genes, RpA1 and Chk1, to be involved in the pathology of a neurodegenerative disease, spinocerebellar ataxia type 1 (SCA1). We also revealed that modulation of the two genes remarkably extended lifespan of SCA1 model flies.
