Yeast proteinopathy models: a robust tool for deciphering the basis of neurodegeneration

November 26, 2015

Protein quality control or proteostasis is an essential determinant of basic cell health and aging. Eukaryotic cells have evolved a number of proteostatic mechanisms to ensure that proteins retain functional conformation, or are rapidly degraded when proteins misfold or self-aggregate. This article discusses the use of budding yeast as a robust proxy to study the intersection between proteostasis and neurodegenerative disease.

The Parkinson’s disease-associated protein α-synuclein disrupts stress signaling – a possible implication for methamphetamine use?

This article comments on work published by Wang et al. (PNAS, 2012), which reported that human α-syn, at high expression levels, disrupts stress-activated signal transduction pathways in both yeast and human neuroblastoma cells. Disruption of these signaling pathways ultimately leads to vulnerability to stress and to cell death.
