Research Interests
The current interest focuses on the methodology development for proteomics. While genomics based on DNA sequencing is now reaching a mature state, an understanding of gene expression and subsequent protein translation has lagged behind. Recent advances in mass spectroscopy related technologies promise to bring protein biochemistry to a level that permits high throughput, global, analysis of protein expression. The application of this technology to biological systems has been termed &proteomics&. Proteomics serves as a platform for global analysis of protein, and aims at analyzing biologically relevant proteins in health and disease state. The current research interest is to develop new technologies for the comprehensive analysis of regulated biological systems and apply these technologies to study the signal transduction pathways that induce and control the hypertrophy of cardiac myocytes under different load conditions. The approach is based on the integration of high-resolution protein separation techniques including two dimensional electrophoresis, high performance liquid chromatography as well as capillary electrophoresis with mass spectrometers. As the number of the gene sequences determined is rapidly increasing, we anticipate that technologies that focus on the characterization of proteins will become essential tools for the comprehensive analysis of biological systems.
