Research Description







Epigenetics: plasticity versus inheritability

DNA is unarguably the carrier of genetic information. However, DNA sequence alone cannot explain how hundreds of cell types in a complex multi-cellular organism, such as a human individual can possess distinct transcription programs, while sharing the same genetic information. This is believed to be achieved by fine-tuning our genetic information with a so-called “epigenetic” system. Epigenetic system must simultaneously offer dual characteristics, “Plasticity & Inheritability”. Plasticity allows the transformation of one genome into hundreds of epigenomes and transcriptomes, whereas inheritability permits the maintenance of every single epigenome and its corresponding transcriptome. Our research focus on the following fields:

1.Establishment and maintenance of epigenetic information

Several histone modifications and DNA methylation have been shown to be critical in classic epigenetic phenomena, including Position effect variegation, Polycomb silencing, dosage compensation and imprinting. Using combinatory approaches by integrating biochemistry, quantitative mass spectrometry, high-throughput sequencing and unbiased screening, we attempt to identify and to mechanistically understand regulatory mechanisms critical for the establishment and maintenance of epigenetic information.

2.Enzymatic activity regulation of chromatin modifying enzymes

Another important direction in our laboratory is to study the biochemical regulation of chromatin modifying enzymes. Despite the exponentially increasing number of studies about chromatin modifying enzymes, the mechanistic regulation of these enzymes is poorly understood. Therefore, we are interested in understanding the molecular mechanisms behind activation and antagonization of chromatin modifying enzymes. We believe this is an important direction for chromatin biology, not only because of mechanistic insights that can be derived from such studies, but also because a mechanistic understanding will contribute to guided small molecule inhibitor design for chromatin modifying enzymes. This goal is particularly important because many chromatin modifying enzymes, such as histone deacetylases (HDACs) and, more recently, PRC2, are being considered as potential drug targets.
