Molecular and Cellular Adaptation(Cooperating field)Human Genetics and Molecular Biology

Introduction

The main research focus of our laboratory is to understand how DNA damage response pathways underpin genome stability.
The integrity of our genome is constantly challenged by both internal and external assaults. To maintain genome stability, we possess a variety of DNA repair pathways and DNA damage checkpoints in response to various DNA insults.
Genome instability syndromes result from defects in DNA repair or DNA damage checkpoint are characterized by predisposition to cancer, immunodeficiency, neurodegenerative disorders, short stature, microcephaly and congenital development abnormalities.
To understand the relationship between DNA damage response pathways and genome instability syndromes, we collect cells derived from patients with genome instability (864 cases, September 2016). Our approach is to find novel disease-causing gene alterations from patient's genome using in-house next-generation DNA sequencing technologies as well as high-content screening. Individual candidates of disease-causing mutations are subjected to functional studies using state-of-the-art technologies. In addition to molecular and cellular analysis, we apply animal models to mimic phenotypes observed in patients with genomic instability.
Our ambition is to carry the knowledge acquired from basic research to clinical fields such as development of new drugs for patients suffering from genome instability diseases.
