Elucidates the structures and dynamics of DNA elements in complex genomes, including physical three-dimensional structures.Visit The Ruan Lab
My primary interest is to elucidate the structures and dynamics of all functional DNA elements in complex genomes through DNA sequencing analysis of genetic variations in genomes and transcriptomes. To facilitate such understanding, my lab and I contribute to the technology development for high-throughput DNA sequencing and mapping methodologies, including the paired-end-tag (PET) sequencing strategy for RNA-PET/Seq, ChIP-PET/Seq, DNA-PET and ChIA-PET analysis. We are applying these sequencing-based methodologies to address complex genetic questions between normal versus disease states. A specific interest is to apply ChIA-PET and related methodologies to understand the three-dimensional (3-D) higher-order structures of chromosomal folding conformation and their impact on nuclear processes, such as gene transcription regulation and DNA replication.

Protein factors are responsible for organizing chromosomes inside the nucleus in three dimensions (3D), forming a shape like a gift bow, with proteins aggregating as the central “knot” holding the ribbon-like loops of DNA when genes are organized for proper expression, or a tangled mess in the presence of certain mutations.
A $3.7 million grant has been awarded to Professor Yijun Ruan, Ph.D., to fund research into how the human genome is organized in the nucleus of the cell.

New sequencing tools are uncovering how the unpacked sections of DNA can interact with each other in three-dimensional space, leading to new insights in the relationships between distant sections of DNA.
Yijun Ruan, Ph.D., received a three-year, $150,000 grant from the National Human Genome Research Institute (NHGRI) to present workshops on a technique for analyzing genomes known as ChIA-PET (for Chromatin Interaction Analysis Using Paired-End Tag Sequencing).
Studying the gastric cancers of 15 Southeast Asian patients, researchers at The Jackson Laboratory, the Genome Institute of Singapore and other institutions identified five recurrent fusion genes, one of which appears to lead to cellular changes involved in acute gastritis and cancer.
National Cancer Institute awards $2.2 M grant to Professor Yijun Ruan for his research into the role of noncoding RNAs in cancer and other diseases.
