Ferroptosis is a pervasive non-apoptotic form of cell death highly relevant in various degenerative diseases and malignancies. The hallmark ferroptosis uncontrolled overwhelming peroxidation polyunsaturated fatty acids contained membrane phospholipids, which eventually leads to rupture the plasma membrane. unique that it essentially spontaneous, uncatalyzed chemical process based on perturbed iron redox homeostasis contributing process, but nonetheless modulated by many metabolic nodes impinge cells' susceptibility ferroptosis. Among affecting sensitivity, several have emerged as promising candidates for pharmacological intervention, rendering ferroptosis-related proteins attractive targets treatment numerous currently incurable diseases. Herein, current members Germany-wide research consortium focusing research, well key external experts who made seminal contributions this rapidly growing exciting field gathered provide comprehensive, state-of-the-art review Specific topics include: basic mechanisms, vivo relevance, specialized methodologies, tools, potential contribution disease etiopathology progression. We hope article will not only established scientists newcomers with an overview multiple facets ferroptosis, also encourage additional efforts characterize further molecular pathways modulating ultimate goal develop novel pharmacotherapies tackle associated - or caused

In the current context of global warming, high temperature events are becoming more frequent and intense in many places around world. this context, understanding how plants sense respond to heat is essential develop new tools prevent plant damage address food security, as threatening agricultural sustainability. This review summarizes integrates our underlying cellular, physiological, biochemical molecular regulatory pathways triggered under moderately extremely conditions. Given that temperatures can also trigger ferroptosis, study cell death mechanism constitutes a strategic approach understand might overcome otherwise lethal events.
