Our lab is focused on the design and application of bioinformatics algorithms to elucidate global epigenetic mechanisms and transcription dynamics in normal development and diseases such as cancer. Since establishing the lab in early 2008, we have published more than 66 peer-reviewed papers in high profile journals, such as Nature, Cell, Nature Genetics, Cell Stem Cell, Molecular Cell, Nature Communications, Genome Research, Genome Biology, PNAS, Genes and Development, Nucleic Acids Research, Cancer Research, and Bioinformatics. We have developed a number of widely used algorithms to analyze next generation sequencing data from ChIP-seq (MACS, MACE, DyChIPS), DNA methylation Bisulfite-seq (BSMAP/RRBSMAP, BSeQC, MOABS), nucleosome positioning MNase-seq (DANPOS), and RNA-seq (CPAT, RSeQC, DaPars). These algorithms have been broadly adopted by thousands of academic users. For example, the MACS algorithm has gathered >1600 citations since 2008. In collaboration with experimental biologists, we used these algorithms to gain novel biological insights from various biological processes and disease models. Chromatin Factors: ER in breast cancer, AR in prostate cancer, FoxA1 pioneer factor, Atoh1 in neuron development, NSD2 in oncogenic programming, SIRT7 in cancer transformation, ZM11 in transcription elongation, and p53 in ES differentiation.. DNA Methylation: DNA methylation Canyon, Epigenetic changes in HSC aging, Dnmt3a in HSC differentiation and cancer transformation. Nucleosome Organization: Fragile nucleosome in stress-response, Promoter nucleosome with Tup1, Nucleosome dynamics in ES differentiation, and Global nucleosome loss in yeast aging. Transcriptome: chimeric RNA in prostate cancer, Long non-coding RNA in HSC, 3’UTR deletion in cancer and its master regulator CFIm25. . Lab Intranet openwetware
