Description

As the average human life expectancy has increased, so too has the impact of ageing and age-related disease on ou society. Ageing research is now the focus of thousands of laboratories that include leaders in the areas of genetics, molecular and cellular biology, biochemistry, and behaviour. Ageing Research Reviews (ARR) covers the trends in this field. It is designed to fill a large void, namely, a source for critical reviews and viewpoints on emerging findings on mechanisms of ageing and age-related disease. Rapid advances in understanding of mechanisms that control cellular proliferation, differentiation and survival are leading to new insight into the regulation of ageing. From telomerase to stem cells to energy and oxyradical metabolism, this is an exciting new era in the multidisciplinary field of ageing research. The cellular and molecular underpinnings of manipulations that extend lifespan, such as caloric restriction, are being identified and novel approaches for preventing age-related diseases are being developed. ARR publishes articles on focussed topics selected from the broad field of ageing research, with an emphasis on cellular and molecular mechanisms of the aging process and age-related diseases such as cancer, cardiovascular disease, diabetes and neurodegenerative disorders. Applications of basic ageing research to lifespan extension and disease prevention are also covered in this journal.

    ABSTRACT: Small noncoding RNAs (sncRNAs) mediate a variety of cellular functions in animals and plants. Deep sequencing has made it possible to obtain highly detailed information on the types and abundance of sncRNAs in biological specimens, leading to the discovery that sncRNAs circulate in the blood of humans and mammals. The most abundant types of circulating sncRNAs are microRNAs (miRNAs), 5′ transfer RNA (tRNA) halves, and YRNA fragments, with minute amounts of other types that may nevertheless be significant. Of the more abundant circulating sncRNAs only miRNAs have well described functions, but characteristics of the others suggest specific processing and secretion as complexes that protect the RNA from degradation. The properties of circulating sncRNAs are consistent with their serving as signaling molecules, and investigations of circulating miRNAs support the view that they can enter cells and regulate cellular functions. The serum levels of specific sncRNAs change markedly with age, and these changes can be mitigated by calorie restriction (CR), indicating that levels are under physiologic control. The ability of circulating sncRNAs to transmit functions between cells and to regulate a broad spectrum of cellular functions, and the changes in their levels with age, implicate them in the manifestations of aging. Our understanding of the functions of circulating sncRNA, particularly in relation to aging, are currently at a very early stage; results to date suggest that more extensive investigation will yield important insights into mechanisms of aging.

    ABSTRACT: Lipid dysfunction, inflammation, immune response and advanced aging are major factors involved in the initiation and progression of atherosclerosis. MicroRNAs (miRNAs) have emerged as important regulators of gene expression that post transcriptionally modify cellular responses and function. MiRNA's are crucially involved in several vascular pathologies which show a clear association with increasing age(Dimmeler and Nicotera, 2013). Several studies have demonstrated that miRNA dysregulation has a in atherosclerotic disease, encompassing every step from plaque formation to destabilization and rupture. This review will present the recent advances in the elucidation of the complex pathophysiological mechanisms in vascular aging by which miRNAs regulate the different phases of atherosclerotic process with a focus on endothelial cells and both, innate and adaptive immune systems. Furthermore, the future areas of research and potential clinical strategies will be discussed.

    ABSTRACT: Non-coding RNAs, such as microRNAs and long non-coding RNAs, represent the next major step in understanding the complexity of gene regulation and expression. In the past decade, tremendous efforts have been put mainly into identifying microRNAs that are changed in Alzheimer's disease, with the goal to provide biomarkers of the disease and to better characterize molecular pathways that are deregulated concomitantly to the formation of Tau and amyloid aggregates. This review underlines the importance of correctly defining, in a deluge of high-throughput data, which microRNAs are abnormally expressed in Alzheimer's disease patients. Despite a clear lack of consensus on the topic, miR-132 is emerging as a neuronal microRNA being gradually down-regulated during disease and showing important roles in the maintenance of brain integrity. Insight into the biological importance of other classes of non-coding RNAs also rapidly increased over the last years and therefore we discuss the possible implication of long non-coding RNAs in Alzheimer's disease.

    ABSTRACT: As the link between metabolism and major disease processes becomes more well-defined, the identification of key molecular targets is leading to new therapeutic strategies. As a result, small non-coding RNA molecules that regulate gene expression via epigenetic alterations, microRNAs have been identified as regulators of these metabolic processes. In the last decade, dietary interventions have been used to change metabolism and to potentially alter disease progression and clinical outcomes. These interventions have been linked, at a molecular level, to microRNAs. This review will summarize the role of various dietary strategies on the expression of several microRNA families.

    ABSTRACT: Background Arterial Stiffness is a known predictor of cardiovascular disease, and has also been associated with markers of cerebral small vessel disease as well as poor cognitive function and cognitive decline. The consistency of these associations and their relationship to each other are unclear. Method We conducted a systematic review of the evidence associating arterial stiffness with cognitive function and cognitive decline, and with makers of cerebral small vessel disease, specifically lacunar infarcts and white matter hyperintensities. Results Thirteen cross-sectional studies examining arterial stiffness and white matter hyperintensities or lacunar infarctions reported a positive association between increased arterial stiffness and radiological findings of cerebral small vessel disease. Two longitudinal studies examining the relationship between arterial stiffness and white matter hyperintensities found increased pulse wave velocity to be an independent predictor of white matter hyperintensity volume. Fifteen cross-sectional and seven longitudinal studies examining arterial stiffness and cognition were identified. Fourteen of the fifteen cross-sectional studies associated increased arterial stiffness with lower cognitive function, and six of the seven longitudinal studies found arterial stiffness to be predictive of cognitive decline. Conclusion Arterial stiffness is associated with cerebral small vessel disease and decreased cognitive function. However methodological limitations such as differing covariates between studies and an over-reliance on the MMSE to measure cognition are a concern across much of the literature.

    ABSTRACT: The skin protects humans from the surrounding environment. Tissues undergo continuous renewal throughout an individual's lifetime; however, there is a decline in the regenerative potential of tissue with age. The accumulation of senescent cells over time probably reduces tissue regenerative capacity and contributes to the physiological ageing of the tissue itself. The mechanisms that govern ageing remain unclear and are under intense investigation, and insight could be gained by studying the mechanisms involved in cellular senescence. In vitro, keratinocytes and dermal fibroblasts undergo senescence in response to multiple cellular stresses, including the overproduction of reactive oxygen species and the shortening of telomeres, or simply by reaching the end of their replicative potential (i.e., reaching replicative senescence). Recent findings demonstrate that microRNAs play key roles in regulating the balance between a cell's proliferative capacity and replicative senescence. Here, we will focus on the molecular mechanisms regulated by senescence-associated microRNAs and their validated targets in both keratinocytes and dermal fibroblasts.

    ABSTRACT: A growing body of evidence shows that microRNA expression changes with age in animals ranging from nematode to human. Genetic studies of microRNA function in vivo provide the means to move beyond correlation and to explore cause-effect relationships. Genetic studies in C. elegans and Drosophila have identified cellular pathways involved in organismal aging. Here, we review the evidence that microRNAs act in vivo as regulators of aging pathways, with emphasis on Drosophila.

    ABSTRACT: The generation of ROS underlies all solar infrared-affected therapeutic and pathological cutaneous effects. The signaling pathway NF-kB is responsible for the induced therapeutic effects, while the AP-1 for the pathological effects. The different signaling pathways of infrared-induced ROS and infrared-induced heat shock ROS were shown to act independently multiplying the influence on each other by increasing the doses of irradiation and/or increasing the temperature. The molecular action mechanisms of solar infrared radiation and heat on human skin are summarized and discussed in detail in the present paper. The critical doses are determined. Protection strategies against infrared-induced skin damage are proposed.

    ABSTRACT: Angiogenesis is generally a quiescent process which, however, may be modified by different physiological and pathological conditions. The "angiogenic paradox" has been described in diabetes because this disease impairs the angiogenic response in a manner that differs depending on the organs involved and disease evolution. Aging is also associated with pro- and antiangiogenic processes. Glycation, the post-translational modification of proteins, increases with aging and the progression of diabetes. The effect of glycation on angiogenesis depends on the type of glycated proteins and cells involved. This complex link could be responsible for the "angiogenic paradox" in aging and age-related disorders and diseases. Using diabetes as a model, the present work has attempted to review the age-related angiogenic paradox, in particular the effects of glycation on angiogenesis during aging.
