Molecular basis of ageing.
Introduction The 94th Annual Boehringer Ingelheim Fonds International Titisee Conference brought scientists from around the world together to discuss recent progress in studies of the basic biology of ageing (biogerontology). The field of biogerontology has seen a marked growth in scientific and popular interest over the past few years, leading to an influx of new investigators working on diver...
متن کاملMolecular mechanisms of skin ageing.
Cutaneous ageing is a complex biological phenomenon consisting of two components; intrinsic ageing, which is largely genetically determined and extrinsic ageing caused by environmental exposure, primarily UV light. In sun-exposed areas, these two processes are superimposed. The process of intrinsic skin ageing resembles that seen in most internal organs and is thought to involve decreased proli...
متن کاملSpectroscopic Studies on the Molecular Ageing of Serum Albumin.
Pathological states in the organism, e.g., renal or hepatic diseases, cataract, dysfunction of coronary artery, diabetes mellitus, and also intensive workout, induce the structural modification of proteins called molecular ageing or N-A isomerization. The aim of this study was to analyze the structural changes of serum albumin caused by alkaline ageing using absorption, spectrofluorescence, and...
متن کاملCellular stress response pathways and ageing: intricate molecular relationships.
Ageing is driven by the inexorable and stochastic accumulation of damage in biomolecules vital for proper cellular function. Although this process is fundamentally haphazard and uncontrollable, senescent decline and ageing is broadly influenced by genetic and extrinsic factors. Numerous gene mutations and treatments have been shown to extend the lifespan of diverse organisms ranging from the un...
متن کاملExercise and skeletal muscle ageing: cellular and molecular mechanisms.
As we age, our skeletal muscle becomes smaller and weaker. In addition, the remaining muscle is more susceptible to damage, particularly following exercise, recovery from damage is severely impaired and muscle is unable to adapt rapidly following sequential periods of exercise. The mechanisms by which skeletal muscle damage occurs are poorly understood and the role that an increased production ...
