Summary
Ferroptosis, an iron-dependent cell death, is regulated by redox imbalance and enzyme activity. Dysregulation of this process is implicated in various diseases, including cancer and neurodegeneration.
Area of Science:
- Biochemistry
- Cell Biology
- Molecular Biology
Background:
- Ferroptosis, an iron-dependent form of non-apoptotic cell death, has garnered significant research interest since its description in 2012.
- This cell death pathway is characterized by a redox imbalance, involving the interplay of oxidants and antioxidants.
- Abnormal expression and activity of redox-active enzymes drive ferroptosis through the accumulation of lipid oxidation products.
Purpose of the Study:
- To review the current understanding of ferroptosis.
- To elucidate the molecular machinery governing ferroptosis.
- To explore the involvement of dysregulated ferroptosis in various pathological conditions.
Main Methods:
- Review of existing literature on ferroptosis.
- Analysis of molecular mechanisms regulating ferroptosis.
- Integration of knowledge on ferroptosis pathways and disease involvement.
Main Results:
- Ferroptosis occurs via extrinsic (transporter-dependent) and intrinsic (enzyme-regulated) pathways.
- Regulation of ferroptosis involves epigenetic, transcriptional, posttranscriptional, and posttranslational mechanisms.
- The transcription factor NFE2L2 and selective autophagy play key roles in ferroptosis modulation.
Conclusions:
- Dysregulated ferroptosis is linked to cancer, neurodegeneration, tissue injury, inflammation, and infection.
- Understanding ferroptosis molecular machinery is crucial for therapeutic strategies.
- Targeting ferroptosis pathways offers potential for treating diverse diseases.

5.6K
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...

01:30Overview of Cell Death
8.5K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

11.3K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

01:29Bone Disorders
4.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
