Environmental Medicine Lab
Machine-translated · View original
A lab that explores the relationship between the environment and health through ferroptosis, a form of cell death.

AboutAbout the lab
Uncovering cell death driven by iron, oxygen, and lipids
The Division of Environmental Medicine is a lab that investigates, from molecules to whole organisms, how the environment affects human health and disease.
Its main keywords are ferroptosis, a form of cell death, redox regulation, oxidative stress, and drug discovery applications.
Ferroptosis is a cell death that arises from the dual nature of iron, oxygen, and lipids. In cancer, inducing it is expected to serve as a treatment strategy, while in conditions such as organ injury, suppressing it may lead to treatment.
This long-established division originated from the Department of Hygiene at Tohoku University, and Professor Eikan Mishima joined it in April 2026.
Key terms
- Ferroptosis
- A form of cell death caused by iron-dependent oxidation of lipids
- Redox
- Oxidation and reduction reactions in which substances exchange electrons. They are related to the conditions inside cells
- Oxidative stress
- A state in which oxidation is enhanced in the body and places a burden on cells

ResearchResearch themes
The lab aims to clarify in an integrated way, from the molecular level to the level of the whole organism, how the environment affects human health and disease, and to return the results to medicine and healthcare. Its research centers on ferroptosis, a form of cell death, investigating its regulatory mechanisms and applications to treatment and drug discovery.
*Illustrative imageRegulation of ferroptosis and its involvement in disease
The lab aims to clarify how ferroptosis is regulated and how it is involved in various disease conditions. Examples of research previously published by Professor Mishima and colleagues include the discovery of the vitamin K and FSP1 pathway, and the intracellular transport of selenium by PRDX6.
*Illustrative imageTreatment and drug discovery targeting ferroptosis
The lab advances treatments and drug discovery that target ferroptosis. Past published examples by Professor Mishima and colleagues include a new system for evaluating the enzymatic activity of GPX4, and the regulation of ferroptosis in cancer through FSP1 inhibition by DHODH inhibitors.
*Illustrative imageExploring unknown redox-related cell death
The lab searches for new redox-related forms of cell death. For modes of cell death that have not yet been identified, it seeks to determine their physiological significance and their potential for application in treatment.
