Singapore scientists lead in 3D mapping of human genome to help understand human diseases
Date:2/1/2012

tant study that sheds light on the complex regulation of gene expression. Yijun's team continues to use the novel method of Chromatin Interaction Analysis with Paired-End-Tag sequencing to probe the higher order interactions of chromatin to discover new regulatory interactions between genes."

"This publication describes ground-breaking work by Dr Yijun Ruan and his team at Genome Institute o Singapore," added Dr Edward Rubin, Director of the Joint Genome Institute in US. "They address the fundamental question of how communication occurs between genes and their on and off switches in the human genome. Using a long range DNA mapping technology called ChIA-PET, the study reveals in three dimensional space that genes separated linearly by enormous distances in the human genome can come to lie next to each other in the cell when it is time for them to become active. I expect this study to move rapidly from primary scientific literature to textbooks describing for future students the operating principles of the human genome. The ChIA-PET technology, that is the telescope used in this exploration of the human genome, is an innovative and powerful molecular technology invented by Dr Ruan and his collaborators."

The ENCODE is an ongoing project which was awarded to Dr Ruan's team by the National Human Genome Research Institute (NHGRI), an institute belonging to the National Institutes of Health (NIH, USA). The project was set up in 2003 with the aim of discovering all functional elements in the human genome to gain a deeper understanding of human biology and develop new strategies for preventing and treating diseases. So far Dr Ruan's team has received over US$2 million towards this project.
