Cdk5 phosphorylation-dependent C9orf72 degradation promotes neuronal death in Parkinson's disease models.

ABSTRACT:

Aims

Chromosome 9 open reading frame 72 (C9orf72) is one of the most dazzling molecules in neurodegenerative diseases, albeit that its role in Parkinson's disease (PD) remains unknown. This article aimed to explore the potential mechanism of C9orf72 involved in the pathogenesis of PD.

Methods

The expression and phosphorylation levels of C9orf72 were examined by Western blotting, RT-PCR, and immunoprecipitation using PD models. Multiple bioinformatics software was used to predict the potential phosphorylation sites of C9orf72 by Cdk5, followed by verification of whether Cdk5-inhibitor ROSCOVITINE could reverse the degradation of C9orf72 in PD. By constructing the sh-C9orf72-knockdown adenovirus and overexpressing the FLAG-C9orf72 plasmid, the effects of C9orf72 knockdown and
