RESEARCH INTERESTS

1. Study the biology and mechanisms of liver development, liver regeneration and hepatocyte cell cycle regulation, as well as liver carcinogenesis using genetically modified mouse models.

2. Study the biological roles of novel genes involved in mouse development, physiological functions, and pathogenesis.

3. Investigate and identify molecular targets and agents for chemoprevention and therapeutic effects of liver cancers and other disease related processes such as ageing.

RESEARCH ACTIVITIES & ACCOMPLISHMENTS

1. Establishment of mouse genetics platform. Since 2000, Dr. Tsai´s lab has established platform for mouse genetic modification methodologies including pronuclear microinjection of transgenic mice, embryonic stem cell manipulation and chimera production for knockout mice, as well as Cre/loxP-mediated chromosome engineering and conditional gene knockout.

2. Study the molecular mechanisms for liver regeneration and carcinogenesis, as well as chemoprevention of liver cancers using genetically modified mouse models. For the past five years since 2003, Dr. Tsai has established various transgenic mice, including HBV X protein transgenics, Aurora-A transgenics, ABIN-2 transgenics and BAC transgenics of ADH genes, and published 5 manuscripts related to this research direction. In addition, she has generated liver-specific androgen receptor knockout and beta-catenin knockout mice to investigate the effects of androgen receptor and beta-catenin on liver carcinogenesis.

3. Investigation of molecular mechanisms for genetic imprinting involved in the Prader-Willi syndrome (PWS) and Angelman syndrome (AS) using genetically modified mouse models. For the past five years since 2003, she has published 3 papers related to this research direction.

4. Improvement of current transgenic technology and generation of mouse models for investigation of novel gene functions. For the past five years since 2003, Dr. Tsai has published 2 papers related to this research direction. In addition, she has successfully filed two provisional patent applications in USA through the United States Patent and Trademark Office. One of the patent (United States Patent 7,067,715) entitled "Combinational Usage of Insulators and Coat Color Marker for High Efficiency Transgene Expression and Visual Genotyping in Mice" was approved on June 27, 2006.
