Management of Insomnia

Management of Insomnia

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...

Mitochondrial Membranes

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,...

Mitochondria

Mitochondria

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,...

Circadian Rhythms and Gene Regulation

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...

Understanding Sleep

Understanding Sleep

Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Area of Science:

Biochemistry
Neuroscience
Gerontology

Background:

Mitochondrial dysfunction is a key factor in aging, ischemia/reperfusion (I/R) injury, septic shock, and neurodegenerative diseases like Parkinson's (PD), Alzheimer's (AD), and Huntington's (HD).
Impaired mitochondrial function is linked to increased free radicals, enhanced nitric oxide (NO) production, decreased respiratory complex activity, and mitochondrial permeability transition pore opening.

Purpose of the Study:

To investigate the role of melatonin in preventing and treating mitochondrial dysfunction.
To evaluate melatonin's therapeutic potential for neurodegenerative disorders and I/R injury.

Main Methods:

In vitro and in vivo studies using experimental models of PD, AD, and HD.
Assessment of melatonin's effects on oxidative stress, nitrosative stress, and mitochondrial bioenergetic function.

Main Results:

Melatonin effectively prevented oxidative and nitrosative stress-induced mitochondrial dysfunction in experimental models.
Melatonin treatment preserved respiratory complex activities, electron transport chain function, and ATP production.
Melatonin demonstrated protective effects against aging, septic shock, and I/R lesions.

Conclusions:

Melatonin acts as a potent antioxidant and regulator of mitochondrial bioenergetics.
Melatonin's selective uptake by mitochondria enhances its therapeutic efficacy.
Melatonin shows significant promise as a therapeutic agent for neurodegenerative diseases and I/R injury.
