  Current Research and Future Directions

  1. Developing novel tools for genome engineering.

  TALEN andCRISPR systems were both discovered in microorganisms. Many enzymes essential for molecular biology, such as the restriction endonucleases, were discovered in microorganisms as well. Thanks to the development of genomics of microbiota and environmental microorganisms, millions of novel genes were discovered, the functions of which remains largely unknown. We are developing bioinformatic methods to identify candidate genes with potential of being novel genome engineering tools. We will screen these enzymes using in vitro biochemical assays and in vivo reporter assay in a high throughput manner, aiming for establishing novel tools that can be used to engineer the genomeof mammalian cells.

  2. Establishment of efficient genome editing platform for therapeutic applications.

  Adoptive cell therapy such as chimeric antigen receptor (CAR) T cell therapy has been applied successfully in treating patients with various hematopoietic malignancies. However, many challenges remain in extending its application toward the treatment of solid tumors. We are aiming to develop more potent CAR-T technologyby applying gene editing to cell therapy. We are also developing high throughput genetic and chemical screening methods for human primary T cells, aiming to identify new targets and chemicals for immunotherapy.

  3. Study the mechanism of X-chromosome inactivation (XCI) in human using stem cell and CRISPR technologies.

  To achieve gene dosage compensation between XX and XY individuals,X-chromosome inactivation (XCI) is evolved in mammals. The process is triggered by the long noncoding RNA Xist, which is expressed from the X-inactivation center (Xic). Although the mechanism of XCI has been studied in great details using mouse as in vivo model and mouse embryonic stem cells as in vitro models, the XCI process in human remains poorly understood due to the lack of proper models. By optimizing naive human embryonic stem cells culture and differentiation protocols, we achieved human random XCI in vitro.Using this platform, we will perform genetic screen using CRISPR technology to dissect the mechanism of XCI in human.

Plain english:
Genome engineering technologies are invaluable tools for understanding the function of genes in development disease. In recent years, the programmable site-specific DNA endonucleases, including zinc finger nucleases (ZFNs), transcription activator–like effector nucleases (TALENs) and the clustered, regularly interspaced short palindromic–repeat (CRISPR) system, have gained tremendous popularity and become widely used for genome engineering in cell lines and animal species ranging from Drosophila to primates. Our laboratory focuses on developing novel technologies to achieve efficient and specific genome engineering, and applying them to study the function of genes and establish novel therapeutic methods.We currently have three main research interests:
1. Developing novel tools for genome engineering
2. Establishment of novel therapeutic methods using gene editing
3. Study the mechanism of X inactivation in human using stem cell and CRISPR technologies
