Our research interest focuses on understanding the connection between cell fate determination and regulatory mechanisms of enhancer elements, which are short cis-acting DNA sequences that can perform regulatory functions to adjust gene transcription in a fine-tuned fashion.
Various transcription factors and epigenetic regulatory mechanisms can control the activation of enhancers during embryonic development and regulate the expression of tissue-specific genes, independent of orientation and over various distances.
We develop bioinformatics tools to analyze high-throughput sequencing data and discover epigenetic changes associated with the activation and silencing of enhancer regulatory elements during embryonic development and carcinogenesis. We construct gene regulatory models to integrate genetic variants, epigenetic modifications and enhancer activation to explain the gene expression regulation in normal and cancer cell fate determination.
