Research Statement

The Zhong Lab uses genetic and cell biology approaches to gain mechanistic understanding of how several neurodegenerative disease-associated proteins disrupt highly conserved cellular processes causing loss of cell integrity and cell death. We work primarily with the budding yeast, Saccharomyces cerevisiae. This single-cell organism is a classical model and one of the best characterized eukaryotes. Owning to the availability of genome-scale genetic tools, S. cerevisiae has become a fascinating system for functional genomics and systems biology research. Many cellular processes are well conserved from yeast to human, making it a viable model for studying human disease. 

One focus of the lab is a protein called α-synuclein, a small lipid-binding protein enriched in the brain. Insoluble misfolded α-synuclein is the primary component of Lewy body, the pathological hallmark of Parkinson's disease. Lewy body pathology is also frequently found in Lewy body dementia and Alzheimer’s disease. Decades after the first discovery of α-synuclein in the Lewy body and mutations in the human gene encoding α-synuclein as genetic causes to Parkinson disease, the cellular function of α-synuclein remains obscure. Aberrant accumulation of α-synuclein induces cellular toxicity in diverse model organisms, including the budding yeast. How such processes are regulated remains unclear. Using high-throughput genetic screens, our lab has identified a network of human genes that promote or reduce the toxicity of α-synuclein. Our current focus is to study the modifier mechanisms underlying each identified toxicity enhancer or suppressor. Our long-term goal is to understand the role of α-synuclein in normal cellular functions and in disease from a global perspective (Funding: NIH/NIA,1R21AG067446-01).
