Summary
Calorie restriction (CR) extends lifespan and improves healthspan across species by inducing metabolic changes. This review explores nutrient signaling pathways and Sirtuin proteins involved in CR
Area of Science:
- Gerontology and metabolic research.
- Molecular mechanisms of aging and longevity.
Background:
- Calorie restriction (CR) is a potent intervention for extending lifespan and ameliorating age-associated disorders in various species.
- CR induces significant metabolic alterations, but the precise mechanisms linking these changes to lifespan extension remain incompletely understood.
Purpose of the Study:
- To review and update current knowledge on nutrient signaling pathways implicated in CR and longevity regulation.
- To discuss the role of Sirtuin family proteins, conserved longevity regulators, in the context of CR.
Main Methods:
- Literature review of recent studies in model systems.
- Synthesis of findings on nutrient signaling pathways and Sirtuin family proteins related to CR and lifespan.
Main Results:
- CR influences multiple conserved nutrient signaling pathways.
- Sirtuins are key molecular players connecting CR to longevity regulation.
- Metabolic changes induced by CR are critical for its life-extending effects.
Conclusions:
- Understanding the molecular mechanisms of CR, particularly nutrient signaling and Sirtuins, is crucial for developing interventions to promote healthy aging.
- Further research in model systems continues to elucidate how CR impacts metabolism and extends lifespan.

01:30Regulation 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...
01:19Regulation 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...
03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:22PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
01:19Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
