Insights

Mitochondria-associated endoplasmic reticulum membranes (MAMs) are key sites for cellular communication. Targeting MAMs may offer protection against toxicant-induced cellular damage and restore homeostasis.

Area of Science:

  • Cell Biology
  • Toxicology
  • Biochemistry

Background:

  • Mitochondria-associated endoplasmic reticulum membranes (MAMs) physically link the endoplasmic reticulum (ER) and mitochondria.
  • MAMs facilitate molecular exchange and crosstalk between these organelles.
  • Mitochondrial and ER dysfunction, along with disrupted cellular homeostasis, are implicated in toxicant exposure.

Purpose of the Study:

  • To review the role of MAMs in toxicological mechanisms.
  • To explore how MAMs mediate cellular responses to toxicants.
  • To highlight MAMs as a potential therapeutic target for toxicant-induced damage.

Main Methods:

  • Literature review of studies on MAMs and toxicology.
  • Analysis of cellular activities regulated by MAMs (e.g., oxidative stress, ER stress, Ca2+ transport, autophagy, apoptosis).
  • Examination of the crosstalk between MAMs-mediated cellular processes.

Main Results:

  • MAMs are crucial for cellular activities affected by toxicants.
  • Toxicant exposure disrupts MAMs structure and function, leading to cellular damage.
  • Interconnected cellular pathways mediated by MAMs are involved in toxicological effects.

Conclusions:

  • MAMs play a significant role in the mechanisms of toxicological effects.
  • Regulating MAMs structure and function can mitigate toxicant-induced damage.
  • MAMs represent a promising target for developing protective strategies against toxicants.

Export of Misfolded Proteins out of the ER01:32

Export of Misfolded Proteins out of the ER

After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

The Endoplasmic Reticulum

The endoplasmic reticulum or ER makes up for more than half of the membranes in a cell and accounts for 10% of total cell volume. It is also the primary protein and lipid synthesis factory for most cell organelles, such as the Golgi apparatus, lysosomes, secretory vesicles, and the plasma membrane. Despite being the most extensive and functionally complex subcellular organelle, ER was the last to be discovered. After years of deliberation, Keith Porter and George Palade in the year 1954,...

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Endoplasmic Reticulum01:39

Endoplasmic Reticulum

The Endoplasmic Reticulum (ER) in eukaryotic cells is a substantial network of interconnected membranes with diverse functions, from calcium storage to biomolecule synthesis. A primary component of the endomembrane system, the ER manufactures phospholipids critical for membrane function throughout the cell. Additionally, the two distinct regions of the ER specialize in the manufacture of specific lipids and proteins.
