Research interests and relevant experience of responsible scientist

The research team of Chen is focused on cloning mammalian genes involved in cell death and aging using yeast as a model system. For this purpose, the bud scar selection system was developed. A collection of genes has been further analysed for resistance against oxidative stress, DNA damage and protein damage phenotype. Some genes of unknown functions are under current studies in mammalian systems and in mice.

In parallel, the laboratory has recently developed a method (DSA-FACE) for measuring bio-fluid (for example, serum/plasma, urine and sperm) N-glycans and generating N-glycosylation profiles of selected proteins. The group has used the DSA-FACE technology to study the glycomics and look for links between N-glycan structural changes and aging phenotypes in serum of transgenic mice, caloric restricted mice and rats, and in different human age groups (e.g. centenarians).

Chen’s team has peculiar experience in high-throughput protein linked N-glycan analysis for disease diagnosis and in development of a biomarker for ageing.
