Summary
Melatonin (MLT) is a potent antioxidant produced in mitochondria, protecting against oxidative damage linked to aging and disease. This molecule may improve mitochondrial function and serves as a potential mitochondria-targeted therapeutic agent.
Area of Science:
- Mitochondrial biology
- Cellular physiology
- Oxidative stress research
Background:
- Oxidative damage contributes to aging and various diseases.
- Mitochondria, the cell's energy producers, are key targets of oxidative stress.
- Mitochondrial dysfunction impacts cellular and tissue interactions, affecting overall physiology.
Purpose of the Study:
- To explore the role of melatonin (MLT) in mitochondria.
- To investigate MLT's potential as a mitochondria-targeted antioxidant.
- To discuss MLT production within mitochondria and its implications for disease.
Main Methods:
- Review of existing literature on melatonin and mitochondrial function.
- Analysis of studies investigating oxidative stress in mitochondria.
- Examination of melatonin's antioxidant properties and cellular localization.
Main Results:
- Melatonin (MLT) is synthesized within mitochondria and acts as a potent antioxidant.
- MLT can mitigate mitochondrial damage caused by oxidative stress.
- MLT exhibits protective effects comparable to synthesized antioxidants.
Conclusions:
- Melatonin is an endogenous, mitochondria-targeted antioxidant with therapeutic potential.
- Disruptions in mitochondrial MLT production may be linked to mitochondrial diseases.
- Melatonin holds promise as a drug for treating conditions associated with mitochondrial dysfunction and oxidative stress.

01:19Management of Insomnia
281
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

01:46Electron Transport Chain: Complex I and II
14.5K
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...

13.9K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

203
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:45Mitochondrial Membranes
11.6K
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,...

01:19Translocation of Proteins into the Mitochondria
3.2K
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
