High expression levels of the D686N Parkinson's disease mutation in VPS35 induces α-synuclein-dependent toxicity in yeast.

ABSTRACT: Parkinson's disease (PD) is a common neurodegenerative disorder that affects ~2% of the human population aged >65. α‑synuclein serves a role in the pathogenesis of PD as it is a primary component of Lewy bodies, a pathological feature of PD. Endosomal‑lysosomal dysfunction may be a key factor involved in the pathophysiology of PD, and may cause PD‑associated neurodegeneration via α‑synuclein‑dependent and ‑independent mechanisms. The D620N mutation in the endosomal‑lysosomal gene, vacuolar protein sorting‑associated protein 35 (VPS35), has been linked to PD. To clarify the underlying cellular mechanism of the VPS35 D620N mutation in PD, cell growth and endosomal‑lysosomal functions were investigated in Saccharomyces cerevisiae (sc) yeast cells that exhibited various expression levels of sc
