Research Background |
Advances in next-generation sequencing (NGS) technologies have created an unprecedented opportunity for the discovery of genetic contribution to human traits and diseases. The overall aim of our group is to understand genetic mechanisms related to human disease processes and characterize implicated genomic mutations and functional changes using high-throughput NGS data. To achieve this goal, we develop and apply computational genomics and bioinformatic approaches and perform integrative analyses of genome, transcriptome, and other multi-omic data.
Computational method development for genomicsequence analysis
We aim to develop computational approaches and statistical models to analyze various data generated by the latest genomic technologies. Genomic and transcriptomic sequences contain enormous information, and there is still room to unravel their meaning. We are particularly interested in the method development for identifying rare somatic mutations that exist only in a small fraction of cell population or even in a single cell.
우리 연구실의 주요 목표 중 하나는 다양한 유전체 데이터를 다각도로 분석할 수 있는 계산 알고리즘 및 통계학적 모델을 만드는 것입니다. 유전체, 전사체 시퀀싱 데이터는 그 자체로도 많은 정보를 담고 있으며, 여전히 숨겨진 의미를 풀 여지가 있습니다. 우리는 다양한 개발 분야 중에서도 유전체 내에 숨겨진 희귀 돌연변이를 식별할 수 있는 고성능 검출 알고리즘 개발에 특히 관심이 있습니다.
Establishing the role of genomic mutationsin human diseases
A large amount of sequencing data and developed computational methods enable us to identify multiple types of mutations in our genome. We aim to characterize various types of mutations from the genomes of patients with multiple diseases, and infer the underlying mechanisms that lead to disease pathogenesis. We are particularly interested in investigating the role of somatic mutations in non-cancerous diseases, especially in brain disorders.
오늘날의 대규모 시퀀싱 데이터와 현재까지 개발된 다양한 계산 알고리즘을 통해 우리는 유전체 내에 존재하는 다양한 유형의 돌연변이를 식별할 수 있습니다. 우리 연구실은 여러 질병의 환자 유전체에서 다양한 유형의 돌연변이를 검출하고, 해당 돌연변이로부터 출발하여 질병으로 이어지는 기저 메커니즘을 연구합니다. 우리는 암 이외의 질환, 특히 희귀질환과 뇌 질환에서 체세포 돌연변이의 역할을 조사하는 데 큰 관심이 있습니다.
Characterization of genomic mutations in a single cell
Advances in single-cell genomics now provide a way to detect various types of somatic mutations even in a single cell genome. The accumulation of somatic mutations has recently been shown to be a hallmark of aging and disease conditions, and their accumulation patterns with genomic context can reveal the underlying mechanisms of mutational processes. We are committed to developing computational methods and analyzing single-cell genome-sequencing data to unveil biological processes in single cells under stressful conditions, especially in single neurons from patients with neurodegenerative diseases.
단일 세포 (싱글셀)을 다루는 기술의 발전을 통해, 우리는 이제 하나의 세포 내에서만 발생한 유전체 돌연변이도 관측할 수 있게 되었습니다. 체세포 돌연변이의 세포 내 축적은 최근 노화와 몇몇 질환의 특징인 것으로 나타났으며, 그 누적 패턴은 어떤 원인에 의해 돌연변이가 발생했는지 생물학적 기작을 유추해 볼 수 있는 중요한 단서를 제공합니다. 우리 연구실은 단일 세포 내의 유전체 변화, 특히 신경퇴행성 질환 환자 뇌의 단일 뉴런에서 유전체 돌연변이를 누적시키는 주요 생물학적 과정을 밝히기 위해 알고리즘을 개발하고 싱글셀 시퀀싱 데이터를 분석하는 등 다양한 노력을 기울이고 있습니다.
