Necrosis01:16

Necrosis

7.2K
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...

Overview of Cell Death

11.0K
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...

The Early Endosome: Endocytosis of Transferrin01:28

The Early Endosome: Endocytosis of Transferrin

5.1K
Essential proteins such as insulin or low-density lipoprotein (LDL) and micronutrients such as iron enter a eukaryotic cell through receptor-mediated endocytosis. Subsequently, the early endosomes fuse with the vesicles containing such receptor-ligand complexes and play a vital role in sorting the incoming ligands and receptors. While the ligands are either degraded inside the vesicle or released into the cytosol, their receptors are returned to the plasma membrane for further rounds of...

The Proteasome01:13

The Proteasome

2.0K
Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Area of Science:

  • Cell Biology
  • Biochemistry
  • Pathology

Background:

  • Ferroptosis is a distinct form of regulated cell death characterized by specific mitochondrial and biochemical alterations.
  • It is implicated in various physiological and pathological conditions, including cancer and neurodegenerative diseases.

Purpose of the Study:

  • To review the molecular mechanisms and signaling pathways governing ferroptosis.
  • To discuss the multifaceted role of ferroptosis in diverse disease contexts.

Main Methods:

  • Literature review of ferroptosis research.
  • Analysis of molecular regulators and signaling pathways involved in ferroptosis induction and inhibition.

Main Results:

  • Ferroptosis is induced by factors affecting mitochondrial function, iron metabolism, and lipid peroxidation, involving pathways like the cystine/glutamate antiporter.
  • Key regulators include glutathione peroxidase 4, NADPH oxidase, and p53, influencing reactive oxygen species (ROS) production and iron uptake.
  • Pharmacological interventions targeting iron chelation and lipid peroxidation can inhibit ferroptosis.

Conclusions:
