Summary
The Nrf2-Keap1 system is a cellular defense against oxidative stress. This review explores its functions, particularly in striated muscle, and its role in oxidative and reductive stress.
Area of Science:
- Cellular biology
- Molecular biology
- Physiology
Background:
- The Nrf2-Keap1 pathway is a conserved defense against oxidative stress.
- Nrf2 is typically degraded but translocates to the nucleus upon stress.
- Nuclear Nrf2 activates gene transcription via Antioxidant Response Elements (AREs).
Purpose of the Study:
- To review the Nrf2-Keap1 system.
- To describe Nrf2 functions and its cross-talk with NF-κB.
- To highlight the system's role in striated muscle physiology and pathophysiology.
Main Methods:
- Literature review of the Nrf2-Keap1 system.
- Analysis of Nrf2 functions and interactions.
- Examination of striated muscle physiology and stress responses.
Main Results:
- The Nrf2-Keap1 system's mechanism of action is detailed.
- Nrf2's role in gene regulation and cellular defense is explained.
- The system's impact on striated muscle under oxidative and reductive stress is discussed.
Conclusions:
- The Nrf2-Keap1 system is crucial for cellular protection against oxidative stress.
- Understanding this system provides insights into muscle health and disease.
- Further research into Nrf2-Keap1 modulation may offer therapeutic strategies.

Oxidation and Reduction of Organic Molecules
9.5K
Energy production within a cell involves many coordinated chemical pathways. Most of these pathways are combinations of oxidation and reduction reactions, which occur at the same time. An oxidation reaction strips an electron from an atom in a compound, and the addition of this electron to another compound is a reduction reaction. Because oxidation and reduction usually occur together, these pairs of reactions are called redox reactions.

Reactions at the Benzylic Position: Oxidation and Reduction
5.1K
The benzylic position describes the position of a carbon atom attached directly to a benzene ring. Benzene by itself does not undergo oxidation. In contrast, the benzylic carbon is quite reactive in the presence of strong oxidizing agents such as KMnO4 or H2CrO4. Therefore, alkylbenzenes are readily oxidized to benzoic acid, irrespective of the type of alkyl groups.

Nitric Oxide Signaling Pathway
6.4K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Oxidation Numbers
43.1K
In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the oxidation number (or oxidation state). It represents the effective charge of an atom or element, which is assigned using a set of rules.

Pyruvate Oxidation
169.4K
After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure that pyruvate can enter the next metabolic pathway so that energy stored in the pyruvate molecules can be harnessed by the cells.
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
