Summary
Ferroptosis, a cell death form, can spread between cells. This review explores how lipid peroxides and iron may drive ferroptosis propagation, impacting disease and development.
Area of Science:
- Cellular biology
- Biochemistry
- Pathology
Background:
- Ferroptosis is a regulated cell death characterized by lipid peroxidation.
- This cell death mechanism exhibits an unusual capacity for intercellular propagation.
- Understanding ferroptosis spread is crucial for its role in disease and development.
Purpose of the Study:
- To review studies on ferroptosis propagation regulators.
- To propose a working model for ferroptosis spread.
- To discuss the implications of ferroptosis propagation in biological contexts.
Main Methods:
- Literature review of studies on ferroptosis propagation.
- Analysis of recent findings on lipid peroxides and iron in ferroptosis.
- Discussion of experimental data on localized vs. long-range propagation effects.
Main Results:
- Lipid peroxides and iron are implicated as key mediators of ferroptosis propagation.
- Sensitizing factors can enhance the spread of ferroptosis induced by specific compounds.
- Ferroptosis propagation can occur through localized and long-range signaling.
Conclusions:
- Ferroptosis propagation, driven by lipid peroxides and iron, is a significant biological phenomenon.
- Understanding propagation mechanisms is vital for addressing degenerative diseases.
- Ferroptosis spread may play a role in normal tissue development and homeostasis.

01:16Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

01:11IP3/DAG Signaling Pathway
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
