What happens when cells are in metabolic stress?
It is important to understand What proteins are capable of sensing cellular stress? How are they altered in metabolic disease? Can these metabolic checkpoints be targeted in metabolic disease?

Develop new therapeutic strategies to treat metabolic diseases
Yoon lab's overall research motivation is to develop new therapeutic strategies to treat metabolic diseases. Traditionally, personalized medicine uses genetic characteristics and biomarkers of a disease to develop metabolic disease treatments, as in the case of cancer. Through my research, we suggest metabolite and nutrition can be used as the basis for the development of new treatments for metabolic diseases.
Develop new therapeutic strategies to treat metabolic diseases
These will be new biomarkers, and will mean finding new metabolic pathways and novel strategies for treatment. This new way to combat metabolic disease using metabolites and nutrients will be relatively stable and reduced side effects. This work will not in only assay development it will also help improve human life and health .

What happens when cells are in metabolic stress?

The Yoon laboratory focuses on the molecular regulation of cellular metabolism in metabolic disease using biochemical, cellular, and mouse modeling experiments approach. Cellular metabolism is altered by stress sensors. Cellular stress-sensors help maintains cell homeostasis. When cellular stress-sensing enzymes or the downstream effectors are dysfunctional, metabolism is rewired and alters cellular metabolic state. Especially, the mitochondrial enzymes of metabolism are tightly regulated by stress-sensing enzymes. Our goal is to investigate what proteins are capable of sensing cellular stress, how are they altered in metabolic disease. Since nutrient deprivation and oxygen deprivation are common stressors that a cell feels, our work focuses on cellular sensors that are responded to oxygen, and nutrient.





세포 에너지 대사 실험실에서는, 스트레스 감지 효소들이 mitochondrial fuel utilization, bioenergetic와 signaling에 미치는 영향을 생화학적 접근 방법으로 세포 및 마우스 모델 등을 이용하여 연구합니다. 신체에서 cellular 스트레스가 발생했을 때, 대사에 관여하는 metabolic enzyme은 stress-sensing enzymes에 의해 조절됩니다. 이런 metabolic 스트레스를 감지하는 효소 또는 하위유전자가 기능 이상일 때, 세포 대사 상태가 변화됩니다. 연구 목적은, metabolic enzyme이 신진 대사 질환에서 어떻게 변화하는지, 그리고 이러한 대사 결정 포인트가 정상적인 생리 및 대사 질환에서 표적연구가 가능한지 입니다. 특히, 영양소 부족과 산소 부족은 세포가 느끼는 일반적인 스트레스 요인이기 때문에, 저희 실험실에서는 산소와 영양소에 반응하는 대사 센서를 연구합니다.
