Necrosis

Necrosis

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...

Protein Modifications in the RER

Protein Modifications in the RER

Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal...

Covalently Linked Protein Regulators

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Phosphorylation

Phosphorylation

The addition or removal of phosphate groups from proteins is the most common chemical modification that regulates cellular processes. These modifications can affect the structure, activity, stability, and localization of proteins within cells as well as their interactions with other proteins.
During phosphorylation, protein kinases transfer the terminal phosphate group of ATP to specific amino acid side chains of substrate proteins. Serine, threonine, and tyrosine are the most commonly...

Translation

Translation

Lesson: Translation
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.

Area of Science:

Biochemistry
Cell Biology
Pathology

Background:

Ferroptosis is a regulated cell death (RCD) pathway characterized by iron-dependent lipid peroxidation.
It is implicated in diseases including cancer, neurodegenerative disorders, and cardiovascular conditions.
Key regulators include ACSL4 and p53 (inducers) and GPX4 and AIFM2/FSP1 (inhibitors).

Purpose of the Study:

To summarize recent findings on ferroptosis mechanisms.
To specifically highlight the role of posttranslational modifications (PTMs) in ferroptosis regulation.

Main Methods:

Literature review of recent advances in ferroptosis research.
Focus on identified pathways and protein regulators.
Analysis of the impact of PTMs on ferroptosis.

Main Results:

Ferroptosis involves at least three major pathways: glutathione-GPX4, FSP1-CoQ10, and GCH1-BH4.
PTMs of proteins play a critical role in modulating ferroptosis.
Specific proteins like ACSL4, p53, GPX4, and AIFM2 are key players.

Conclusions:

Ferroptosis is a complex RCD with multiple regulatory pathways.
Posttranslational modifications are crucial for fine-tuning ferroptosis.
Understanding these mechanisms offers potential therapeutic targets for ferroptosis-related diseases.
