Cellular Presymptomatic Engineering Research Group Overview

We are exploring functional ingredients that improve aging and the associated sarcopenia, and elucidating their mechanisms of action. We are also searching for biomarkers that contribute to the early detection of mental disorders such as sleep disorders and depression. By integrating multiple cellular and animal models, we are promoting industry-academia-government collaboration to extend healthy life expectancy.

Cellular Presymptomatic Engineering Research Group Overview

Research Project

Project 1:Development of evaluation techniques for the prevention of neurological dysfunctions associated with aging
Researcher: SHINKAI Yoichi

Aging is a risk factor for various neurological diseases such as ALS and Alzheimer's disease. In recent years, there has been a growing interest in the development of methods to control and visualize liquid-liquid phase separation for the fundamental treatment and early diagnosis of neurological diseases associated with this aging process. Using the short-lived nematode C. elegans, I am developing a high-throughput evaluation system for human cells. In addition, I am also exploring functional substances that contribute to disease prevention and preemptive measures by utilizing these evaluation systems.

Project 2:Development of antiaging technology using chrono-nutrition
Researcher:OISHI Katsutaka

Japan is a super-aged society. In order to achieve an extension of the healthy life expectancy, it is important to prevent aging-related diseases such as sleep disorders and impaired cognition. Recent studies have revealed that circadian clock is involved in the onset of these aging-related diseases. This “Chrono-nutrition” project is focused on the development of natural substances and technologies for the prevention of sleep disorders, psychiatric diseases, impaired cognition, and metabolic diseases such as obesity and diabetes.

Project 3:Influence of triggered genes under progressions of depression and the related diseases
Researcher:KUWABARA Tomoko

Elucidation of the mechanisms between depression and related multiple disorders. Identification of gene expression mechanism, cell regulatory systems in multiple organs. Development of diagnostic techniques for diabetes, psychiatric and neurological disorders. Establishment of innovative strategies for diagnosis, prevention, and treatment of depression and related disorders.

Project 4:Development of novel diet therapy for skeletal muscle health
Researcher:ABE Tomoki

Skeletal muscle comprises about 40% of body weight in human and plays important roles in regulate energy metabolism and brain function. We aim to develop a novel diet therapy to improve quality and quantity of skeletal muscle.

Project 5:Elucidation of the Pathogenesis of Diseases Caused by Psychological Stress and Development of Pre-disease Markers
Researcher:SATO Tomoyuki

Psychological stress is known to increase the risk of developing liver and heart diseases. This project aims to elucidate the effects of psychological stress on the liver and heart using mainly social psychological stress model mice, and to develop pre-disease markers that can predict disease onset. In addition, we are working on elucidating the mechanisms of onset of liver and neurological diseases using cultured cells and isolated mitochondria, as well as developing intervention methods based on lifestyle habits.

Project 6:Exploration of aging factors and mechanisms of exercise-induced pre-disease improvement
Researcher:LEE Minjung

In super-aged societies, extending healthy life expectancy is a critical issue. Aging is known to increase the risk of various diseases such as cancer and dementia. To address this, our research aims to elucidate the molecular mechanisms of aging by exploring aging-related factors using aging-accelerated model mice. Furthermore, we focus on exercise, which is believed to support health from the pre-disease stage and conduct exercise intervention experiments using laboratory animals. In parallel, we are also developing exercise-mimicking technologies at the cellular level to replicate its physiological effects. Through these studies, we aim to uncover novel molecular mechanisms involved in aging and pre-disease progression, as well as to clarify the scientific basis for the health benefits of exercise.
