4. Ageing across the life span: time to think again.
Match Strength: 10.556

Living organisms are subject to ageing. This natural process has gained greater importance in socially and medically affluent societies. For many, ageing connotes unattractive changes in the appearance of the skin. The gross morphological changes of ageing skin are mirrored by a range of more profound age-associated physiological declines. Thus, skin ageing can be put into other perspectives which lie at the interfaces of molecular biology, cellular biology, oncology and cosmetic dermatology. Genetically programmed replicative senescence and stress-induced premature senescence (SIPS) are two ... Read More »

6. Mitochondrial DNA and ageing.
Match Strength: 10.201

The accumulation of mitochondrial DNA mutations has been proposed as a potential mechanism in the physiological processes of ageing and age-related disease. Although mitochondria have long been anticipated as a perpetrator of ageing, there was little experimental evidence to link these changes directly with the cellular pathology of ageing. Recently, considerable progress in understanding basic mitochondrial genetics and in identifying acquired mtDNA mutations in ageing has been made. Furthermore, the creation of mtDNA-mutator mice has provided the first direct evidence that accelerating the ... Read More »

7. Theories of ageing.
Match Strength: 10.180

Ageing is a universal, intrinsic, progressive and deleterious process. Understanding it is of major interest to scientist, physicians as well as to the general population. Critical to this understanding is to formulate comprehensive theories of aging with high predictive and explanatory power. More than 300 theories have been postulated and are reviewed here. The free radical theory of ageing is one of the most prominent and well studied. It was further developed by one of us (JM) in what has become known as the mitochondrial theory of ageing. These theories provide new experimental approaches ... Read More »

8. Programmed and altruistic ageing.
Match Strength: 10.036

Ageing is widely believed to be a non-adaptive process that results from a decline in the force of natural selection. However, recent studies in Saccharomyces cerevisiae are consistent with the existence of a programme of altruistic ageing and death. We suggest that the similarities between the molecular pathways that regulate ageing in yeast, worms, flies and mice, together with evidence that is consistent with programmed death in salmon and other organisms, raise the possibility that programmed ageing or death can also occur in higher eukaryotes.

11. Ageing and apoptosis.
Match Strength: 9.933

Ageing is accompanied by a general decline of physiological function, especially at later stages, and significant increases in the incidence of cancer and other degenerative diseases. It has recently been hypothesized that alterations in apoptosis may contribute to these age-associated changes. However, whether there is a role for apoptosis in the ageing process and how ageing may modify the regulatory machinery of apoptosis remains obscure. Although the literature addressing these issues is scarce, research in this area is gaining momentum. Molecules involved in apoptosis signaling in mammals ... Read More »

12. Insulin Receptor and Ageing
Match Strength: 9.839

The number of elderly people is increasing worldwide as well as the age-associated diseases, such as the type 2 diabetes. The consequences are disastrous for elderly patients as well as for healthy ageing. It has been clinically demonstrated that with physiological ageing it exists already a resistance to the action of insulin leading to slightly increased glycemia and insulin levels. Several causes have been postulated for this insulin resistance with ageing, among them the alteration of insulin receptor (IR) number, of IR signal transduction as well as environmental changes.

In the developing field of biological gerontology, rapid advances have recently been made in the genetics of ageing in the nematode Caenorhabditis elegans. The aim of this work is to develop an understanding of the general mechanisms determining the ageing process. Within the last decade the prospect of actually achieving this somewhat hubristic aim has begun to look startlingly real. In this context, knowledge of every aspect of the biology of ageing in nematodes is of added interest. Here the patterns of ageing observed among parasitic and free-living nematodes are surveyed and compared. ... Read More »

16. Physiological ageing: role of p53 and PARP-1 tumor suppressors in the regulation of terminal senescence.
Match Strength: 9.180

Ageing of organisms is among the most complex processes currently known. Understanding the molecular mechanism of physiological ageing is one of the most essential issues in biology and medicine because it is not possible to predict when and how a certain individual will start ageing. In the past centuries human life expectancies increased. Extension of life span is associated with increased susceptibility to a number of chronic diseases. Insight into the cellular and molecular targets of the ageing process would offer the opportunity to prevent at least some of the destructive processes. In ... Read More »

Gerontology has made considerable progress in the understanding of the mechanisms underlying the ageing process and age-related neurodegenerative disorders. However, ways to improve quality of life in the elderly remain to be elucidated. It is now clear that stress and the ageing process share a number of underlying mechanisms bound in a very close, if not indissociable, relationship. The ageing process is regulated by the factors underlying the ability to adjust to stress, whilst stress has an influence on the life span and the quality of ageing. In addition, the ability to cope with stress ... Read More »

Match Strength: 8.721

Rate of ageing in tyrannosaurs was calculated from parameters of Weibull functions fitted to survival curves based on the estimated ages at death of fossilized remains. Although tyrannosaurs are more closely related to birds than to mammals, they apparently aged at rates similar to mammals of comparable size. Rate of growth in body mass of tyrannosaurs was similar to that of large mammals, and their rates of ageing were consistent with the estimated extrinsic mortality, which is strongly correlated with the rate of ageing across birds and mammals. Thus, tyrannosaurs appear to have had life ... Read More »

27. Increased p53 activity does not accelerate telomere-driven ageing.
Match Strength: 8.637

There is a great interest in determining the impact of p53 on ageing and, for this, it is important to discriminate among the known causes of ageing. Telomere loss is a well-established source of age-associated damage, which by itself can recapitulate ageing in mouse models. Here, we have used a genetic approach to interrogate whether p53 contributes to the elimination of telomere-damaged cells and its impact on telomere-driven ageing. We have generated compound mice carrying three functional copies of the p53 gene (super-p53) in a telomerase-deficient background and we have measured the ... Read More »

The thermoluminescence (TL) parameters in intact leaves and thylakoids isolated from leaves showed a different pattern of change during leaf ageing. Ageing of leaves brought about a decrease in the B-band and a simultaneous increase in the Q-band. Thylakoids showed only a decrease in the B-band. The TL bands further show that there is generation of an endogenous electron transport inhibitor during leaf ageing. Copyright 2001 John Wiley & Sons, Ltd ... Read More »

Caloric restriction in animal models delays many age-related pathological conditions. Ageing rats have characteristically increased body weight, fat mass and a specific body fat distribution. This report will focus on the potential cause-effect relationship between increased fat mass and accelerated ageing. In humans, increased fat mass (obesity), and in particular increases in abdominal obesity as a result of deposition of visceral fat, are associated with the metabolic syndrome of ageing. This syndrome is associated with hyperinsulinaemia, dyslipidaemia, type 2 diabetes mellitus, ... Read More »

30. Signaling pathways regulating protein synthesis during ageing.
Match Strength: 8.562

Ageing in many organisms, including humans, is accompanied by marked alterations in both general and specific protein synthesis. Protein synthesis is normally under tight control by a broad array of regulatory factors, which facilitate appropriate rates of mRNA translation. Are the wide changes in protein synthesis simply a corollary of the ageing process or do they have a causative role in senescent decline? The jury is still out on this important question. Nevertheless, recent studies reveal an intimate interface between mechanisms that govern the translation of mRNA and molecular pathways ... Read More »

Match Strength: 8.518

In this keynote address, we briefly consider three global questions on the biology of ageing. What is it? While it is certainly the case that development has a major impact upon ageing, gerontologists characterize ageing as gradual, insidious, post-maturational declines in the structure and function of multiple organ systems, certainly to include reproduction. This is accompanied by increasing rates of mortality within populations. Comprehensive, longitudinal physiological assessments are not commonly pursued in their experiments, however; this deficiency limits one's ability to interpret the ... Read More »

By the mid 1970s, the mechanisms by which ageing can evolve had a secure theoretical basis in population genetics. Here, we discuss how subsequent evolutionary work has focussed on testing and extending this theory, and on attempting to integrate it with other emerging facets of the biology of ageing, such as genetic studies of long-lived mutants and of phenotypic plasticity in ageing, such as in response to nutritional status. We also describe how functional genomic studies are providing new insights into the evolutionary forces shaping genome evolution and lifespan control. Future challenges ... Read More »

34. Telomeres and telomerase biology in vertebrates: progress towards a non-human model for replicative senescence and ageing.
Match Strength: 8.460

Studies on telomere and telomerase biology are fundamental to the understanding of human ageing and age-related diseases such as cancer. However, human studies of whole body ageing are hampered by the lack of suitable fully reflective animal model systems, the wild-type mouse model being unsuitable due to differences in telomere biology. Here we summarise recent data on the biology of telomeres, telomerase, and the tumour suppressor protein p53 in various animals, and examine their possible roles in replicative senescence, ageing, and tumourigenesis. The advantages and disadvantages of various ... Read More »

35. Telomere attrition as ageing biomarker.
Match Strength: 8.455

Telomeres, the tandem-repeated hexamers at the termini of mammalian chromosomes, form protective complexes in association with specific proteins that together with telomerase, a specialised telomere-synthesizing enzyme, regulate telomere length. Telomere shortening is associated with cellular senescence and is implicated in tumorigenesis and cancer. Hence, mean telomere length has emerged as a replicative clock within each population of cells and the tissues and organs they build up in vitro and, consequently, as a biomarker for biological ageing in vivo. Chronological ageing per se does not ... Read More »

37. The Gompertz function does not measure ageing.

The Gompertz transform of the distribution function for the age at death expresses mortality in a form R = R0e(alphat) where R0 is the mortality at time zero and alpha is the rate of increase of mortality, frequently taken as the rate of ageing. The slope of the line alpha is frequently used as a measure of the rate of ageing. It is argued that it is incorrect to use alpha in this way. To support this contention, a paradox is produced whereby selection for longevity increases alpha, which could lead to the absurd conclusion that selection for longevity increases the rate of ageing.

The rate of ageing is a genetically influenced feature of an individual's life history that responds to selection on lifespan. Various costs presumably constrain the evolution of prolonged life, but these have not been well characterized and their general nature is unclear.

The effects of chronic sun exposure on skin are readily apparent when skin not typically exposed to the sun and skin regularly exposed to the sun are compared. While the sun is not the only aetiological factor in the dynamic process of skin ageing, it is the primary exogenous cause among several internal and environmental elements. Thus, photo-ageing, the main focus of this article, is a subset of extrinsic skin ageing. The influence of the sun in extrinsic skin ageing, as well as its role in potentially altering the normal course of intrinsic (also known as natural or cellular) ageing, is ... Read More »

47. Ageing and dexamethasone associated sarcopenia: Peculiarities of regeneration.
Match Strength: 8.239

The purpose of this study was to assess the development of ageing- and glucocorticoid-related sarcopenia on the level of myofibrillar apparatus, paying attention to the synthesis (SR) and degradation rate (DR) of contractile proteins, muscle strength, and daily motor activity. We also wanted to test the effect of ageing and dexamethasone (Dex) excess on the regeneration peculiarities of skeletal muscle autografts. Four and 30-month-old male rats of the Wistar strain were used. Ageing associated sarcopenia was calculated from gastrocnemius muscle relative mass decrease (from 5.6+/-0.08 to 3.35+ ... Read More »

48. Controversial endocrine interventions for the aged.
Match Strength: 8.235

Specific endocrine changes occur with the ageing process. The last decade has witnessed significant progress in the basic and clinical science of ageing, thereby rejuvenating the interest in anti-ageing medicine, especially that of hormone replacement, by medical professionals and the lay public. However, endocrine manipulation as a therapeutic strategy for ageing is still evolving as continuing research attempts to answer the many questions of what it can achieve at the risk of incurring unknown long-term adverse effects. The current day doctor is confronted with a host of options, and will ... Read More »

49. Effects of Ageing on Insulin Secretion and Action
Match Strength: 8.232

One of the many conditions associated with ageing is type 2 diabetes mellitus, the prevalence of which increases from 20-30 years of age onwards. In many cases, type 2 diabetes mellitus is caused by the combination of insulin resistance and poor insulin secretion. Insulin resistance is also a risk factor associated with other disorders, in particular cardiovascular disease. Physiological changes associated with ageing, such as changes in body composition, decreased physical fitness, changes in hormones, and the secondary effects of high levels of free fatty acids and glucose, may also ... Read More »

50. Neuroprotective and anti-ageing effects of curcumin in aged rat brain regions.
Match Strength: 8.182

This study investigated the influence of chronically administered curcumin on normal ageing-related parameters: lipid peroxidation, lipofuscin concentration and intraneuronal lipofuscin accumulation, activities of the enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx), and Na(+), K(+), -adenosine triphosphatase (Na(+), K(+), -ATPase) in different brain regions (cerebral cortex, hippocampus, cerebellum and medulla) of 6- and 24-month-old rats. In normal ageing, lipid peroxidation and lipofuscin concentration were found to increase with ageing, the activities of SOD, GPx and Na(+), ... Read More »
