Summary
The insulin/IGF-1 pathway influences aging and lifespan across species. Genetic variations, particularly in the FOXO3A gene, are linked to increased human longevity in diverse populations.
Area of Science:
- Genetics
- Aging Research
- Molecular Biology
Background:
- The insulin/IGF-1 signaling pathway plays a crucial role in regulating lifespan and aging processes.
- This pathway's influence extends across various model organisms, including worms, flies, and mice.
- Genetic variations within this pathway are hypothesized to impact human longevity.
Purpose of the Study:
- To review existing evidence on the insulin/IGF-1 pathway's effect on longevity.
- To focus on genetic studies investigating the pathway's role in human lifespan.
- To identify specific genes within the pathway associated with human longevity.
Main Methods:
- Literature review of genetic studies on the insulin/IGF-1 pathway and human longevity.
- Analysis of findings from diverse ethnic populations.
- Identification of consistently associated genes.
Main Results:
- The insulin/IGF-1 pathway is a significant modulator of aging and lifespan.
- Genetic variations within this pathway are associated with human longevity.
- The FOXO3A gene, a homolog of C. elegans daf-16, shows consistent associations with increased lifespan across multiple studies and populations.
Conclusions:
- The insulin/IGF-1 pathway is a key genetic determinant of human longevity.
- FOXO3A represents a significant genetic factor contributing to extended lifespan in humans.
- Further research into this pathway could reveal novel targets for interventions against age-related decline.

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...
01:28Insulin: The Receptor and Signaling Pathways
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but this inhibition is released...
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...

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.

01:22Diversity in Cell Signaling Responses
The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.

01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
