Research Interests
Our study focuses on RNA biology in stem cells and cancers . By combining virous research approaches, including biochemistry, molecular biology, high-throughput sequencing, bioinformatics, etc., we aim to identify novel RNA regulatory pathways, and to further investigate their biological relevance in Embryonic Stem Cells and early embryonic development. We are also interested in rebuilding plants and microbiology specific RNA regulatory pathways (proteins) in mammalian cells to explore their potential medical applications.
Main projects:
1, To identify novel RNA regulatory elements and study on the related regulatory mechanisms.
2, To investigate the roles of RNA regulation on ESCs totipotency and pluripotency transitions.
3, To reconstitute RNA regulatory pathways (proteins), which are unique in plants or microbiology, in mammalian cells and to investigate their potential applications in medicine.

Laboratory Introduction
Our research focuses on RNA biology in stem cells and cancers.
In one of our recent studies, for the first time, we realized capture and maintenance of totipotent stem cells, which are comparable to 2- and 4-cell blastomeres with highest developmental potential, by using a splicing repression strategy (Cell, 2021). Based on this, we plan to optimize our culture medium to enable capturing totipotent stem cells from different species. Furthermore, based on these totipotent stem cell, we would like to develop various differentiation system to obtain different functional somatic cells or organoid for the future regeneration medicine.
Recently, using biochemical and molecular biology approaches, we identify a novel micoRNA dosage control mechanism governed by a promoter switch event, which controls germ layer specification during early development (Nature, 2021) . As well, we are interested in cross-spaces bio-engineering, and have successed to build a broad anti-tumor response in mammals using a plant immune protein RDR1 through microRNAs. We will continue to discover novel RNA regulatory mechanisms, investigate their physiological functions and explore the potential medicine applications.
