DNA is the template for DNA replication and RNA transcription, making the maintenance of genome integrity extremely important. The Wu laboratory focuses on understanding mechanisms of genome instability in physiological and pathological processes. By developing bioinformatic approaches and sequencing techniques to probe repair associated DNA synthesis (SAR-seq) and DNA breaks (ENDseq), we aim to explore:
By developing two novel sequencing-based approaches to map single strand breaks (SSBs) and repair synthesis in post-mitotic neurons, we discovered that neuronal enhancers are hotspots of endogenous SSBs and are repaired by both short- and long-patch base excision repair. Furthermore, the SSBs are associated with TET-mediated active DNA demethylation. (Wu, W. et al. Nature, 2021;Wang, D.*,Wu, W*,Callen,E*. et al. Science, 2022).
By utilizing genome-wide DNA double strand break detection assay ENDseq, we have directly probed murine meiotic double strand breaks and end resection. Also, we demonstrated the roles of multiple key regulatory factors in meiotic DSB processing such as ATM, DMC1, PRDM9, and identified a novel SPO11-bound recombination intermediate. (Paiano, J.*, Wu, W.*, et al. Nature communications, 2020).
Repetitive sequence is a major source of DNA damage. They usually are unstable and can form various secondary structures in vivo, including G4 quadruplex, triplex-DNA, cruciform, especially in the absence of mismatch repair. By applying ENDseq and its variants, we have discovered several types of fragile repeats in replication and cancers. (Matos-Rodrigues, G., et al. Molecular Cell, 2022; van Wietmarschen, N., et al Nature, 2020; Tubbs, A., et al. Cell, 2018)
About the PI
Dr. Wu received her B.E. in bioinformatics from Huazhong University of Science and Technology in 2012 and obtained her Ph.D. from the institute of biophysics of the Chinese Academy of Sciences in 2017, where she studied long non-coding RNA in cancer and noncoding RNA associated database development at the laboratory of Prof. Runsheng Chen. As a postdoctoral fellow in the laboratory of Dr. André Nussenzweig at the National Cancer Institute, she focused on studying mechanisms of DNA damage and repair by utilizing various novel sequencing technologies and bioinformatics analysis. She has received many awards during her training, including Fellows Award for Research Excellence, NCI Director’s Innovation Award, etc.
