Research Interests:
RNA splicing removes large numbers of introns in higher eukaryotes, for example, there are over 300,000 introns in the human genome. The dynamic assembly of the spliceosome and the diversified types of intron selection are critical for the regulation of gene expression, closely related to physiological processes such as cell differentiation and organ development. Importantly, the aberrant splicing results in various human diseases. We are interested in the regulatory mechanisms of RNA splicing during the development and diseases and focus on the below directions:
1) Regulatory mechanisms of alternative splicing, trans-splicing, and back-splicing;
2) The dynamic assembly of minor spliceosomes and the function of minor intron-containing genes in neurodegenerative diseases;
3) Regulatory functions of the highly conserved intronic cis-elements across species on organ development and energy metabolism;
4) Regulatory mechanisms of splicing factors with high-frequent mutations in the occurrence and development of neurological, metabolic, tumor, and hematological diseases;
5) Biogenesis, functions, and applications of circular RNAs.
