Mitochondrial function and protein modification
Metabolomics, biosensors, stable isotope tracing
Another focus of our research is to develop mitochondria based cell protection. We recently revealed an important role of redox-sensitive protein acetylation in modulating mitochondrial protein interactome that in turn dictates cellular sensitivity to stress. We are now developing novel technologies with our collaborators, e.g. biosensors, quantitative proteomics and high throughput screening, to determine and target the nodal points of mitochondria-originated injury pathways.
