Summary
Sleep deprivation (SD) causes aging-like effects on learning and memory. This study found that acute sleep deprivation in mice induces metabolic changes similar to aging, particularly in the liver and plasma.
Area of Science:
- Metabolomics
- Neuroscience
- Aging Research
Background:
- Sleep deprivation (SD) is linked to neurodegenerative and cardiometabolic diseases.
- SD can accelerate cognitive decline, mimicking aging processes.
- The molecular links between SD and aging remain largely unexplored.
Purpose of the Study:
- To investigate the common molecular underpinnings of sleep deprivation and aging.
- To profile metabolic changes in response to acute SD in young and aged mice.
- To identify a metabolic signature associated with sleep loss and aging.
Main Methods:
- Acute sleep deprivation (5 hours) was applied to young adult and aged mice.
- Metabolic profiling of blood plasma, hippocampus, and liver was performed using UPLC-MS/MS.
- Comparative analysis of metabolic profiles based on age and sleep status.
Main Results:
- Sleep deprivation primarily affected peripheral plasma and liver metabolism, including ketone body and nicotinamide pathways.
- Aging had a more pronounced impact on hippocampal metabolism.
- Aged mice exhibited baseline metabolic features resembling those of sleep-deprived young mice.
- A distinct set of nine metabolites could classify animals based on age and sleep status with 79% accuracy.
Conclusions:
- Metabolic alterations induced by sleep deprivation show significant parallels with aging processes.
- This study defines a molecular metabolic signature for sleep loss and aging.
- Findings suggest that sleep deprivation can induce aging-like metabolic changes.

Insufficient Sleep and Sleep Deprivation
160
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

Aging
72
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

The Effect of Aging on Tissues
2.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Metabolic States of the Body: Fasting and Starvation
1.5K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Mitochondria
13.7K
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,...

Bone Disorders
3.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
