Mechanisms of Ageing and Development
|December 2, 1999
Summary
Genetic studies reveal that genes influencing Gompertz parameters may explain lifespan variability in genetically identical mice, a key factor in aging research.
Area of Science:
- Gerontology
- Genetics
- Animal Models
Background:
- Aging is a complex, polygenic trait with unresolved underlying mechanisms.
- Genetically identical organisms, like inbred mice, exhibit lifespan variability, challenging traditional genetic explanations.
- A previous study identified a locus on chromosome 11 controlling this lifespan variability in mice.
Purpose of the Study:
- To propose a mechanism explaining lifespan variability in genetically identical organisms.
- To identify candidate genes responsible for the observed lifespan variation.
Main Methods:
- Analysis of genetic factors influencing lifespan in inbred mouse models.
- Investigating the relationship between gene expression and lifespan parameters.
Main Results:
- Genes affecting Gompertz parameters are identified as potential candidates for causing lifespan variability.
- This finding offers a mechanistic explanation for lifespan variation in genetically uniform populations.
Conclusions:
- Genes influencing Gompertz parameters provide a plausible explanation for lifespan variability in genetically identical mice.
- Understanding these genetic mechanisms is crucial for advancing aging research and genetic studies.

01:29Life Histories
Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off is represented by two primary reproductive strategies; K-strategists produce few offspring but provide substantial parental support, whereas r-strategists produce much progeny that receives little care. These strategies are related to an organism’s survival likelihood across its lifespan, which is represented by a survivorship curve. Three general types of...
01:49Hardy-Weinberg Principle
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.In the early 20th century,...
01:09Mutation, Gene Flow, and Genetic Drift
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).Mechanisms of Genetic VariationThe original sources of genetic variation are mutations,...
01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
02:27Background and Environment Affect Phenotype
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:22Life Tables
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...
