Mitochondria01:37

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,...
Aging01:26

Aging

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 Tissues01:19

The Effect of Aging on Tissues

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...
Regulation of Food Intake01:30

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
Metabolic States of the Body: Fasting and Starvation01:24

Metabolic States of the Body: Fasting and Starvation

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...
Regulation of Metabolism01:19

Regulation of Metabolism

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Area of Science:

  • Gerontology and aging research.
  • Molecular biology and epigenetics.
  • Nutritional science and intervention studies.

Background:

  • Calorie restriction (CR) is a well-established method for extending lifespan and healthspan in various organisms.
  • CR's efficacy in counteracting aging effects has made it a gold standard in aging intervention studies.
  • Research has evolved from using CR to understand aging mechanisms to its application in preventing age-related decline and diseases.

Purpose of the Study:

  • To review the major mechanisms underlying the anti-aging effects of calorie restriction.
  • To highlight the role of CR in modulating chronic inflammation and epigenetic modifications.
  • To summarize research on CR mimetics like rapamycin and intermittent feeding patterns.

Main Methods:

  • Review of existing literature on calorie restriction and aging.
  • Analysis of molecular mechanisms, including inflammation and epigenetics.
  • Comparison of CR with other interventions like rapamycin and intermittent feeding.

Main Results:

  • CR demonstrably extends median and maximum lifespan while suppressing age-related diseases in animal models.
  • CR's benefits are linked to the modulation of chronic inflammation and epigenetic changes at gene expression control sites.
  • Emerging research in non-human primates and humans suggests potential benefits for healthy aging.

Conclusions:

  • Calorie restriction is a powerful intervention for promoting longevity and healthspan.
  • Understanding CR's molecular targets, such as inflammation and epigenetics, is crucial for developing anti-aging strategies.
  • Further research, including studies on CR mimetics and intermittent feeding, holds promise for translating CR benefits to human populations.
