Developing metabolomics for a systems biology approach to understand Parkinson's disease
Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

stable-isotope labeling: exploring neuronal metabolism related to Parkinson’s disease
The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

Studies on the Pathogenesis of Chronic Kidney Disease
In this thesis, two potential therapeutic targets for diabetic nephropathy were dentified and investigated. First, we show that glomerular clusterin is upregulated in diabetic nephropathy and demonstrated that recombinant clusterin protein can protect the podocytes against oxidative stress in vitro.…
