Telomeres,and play an essential role in cellular longevity. These specialized structures undergo dynamic changes during cellular divisions and act as protective caps, preventing the loss of coding genetic material (due to peculiarities of the replication process) and the fusion of chromosomal ends. They also

Epigenetic Changes in Aging: The Contribution of SIRT1 to Longevity,n aged organisms, a noticeable reduction in histones levels is accompanied by both local and global chromatin remodeling. This shift creates an imbalance between activating and repressive histone modifications, resulting in widespread transcriptional changes observed in various aging models. Sirtuin

Proteostasis, Proteodynamics and Cellular Aging,out which the cell could not function properly. Organismal and cellular aging imposes stresses, constrains and dysfunctions on each and every stage of protein manufacturing, maturation and maintenance, as well as on the efficiency of removal of those proteins that were malformed (e.g. misfolded) fro

Mitochondria and Ageing,dered a regular process occuring in all living organisms, aging is associated with accumulative oxidative damage of cellular biomolecules and with increased susceptibility to age-related diseases. Mitochondria are central organelles in energy metabolism by housing several metabolic pathways and prod

The Senescence-Associated Secretory Phenotype: Induction, Regulation, Function and Therapeutic Inteal of advanced age. Among the causes responsible for the induction of this status, the accumulation of senescent cells in the body play a relevant role. This chapter summarizes the features of senescent cells, how they are induced and maintained in the body and how they can contribute to the develop

Cellular Senescence, which senescence is induced, mostly related to stresses inducing some type of DNA damage. Currently, cellular senescence is studied particularly in relation to aging and cancer. Data from animal experiments attribute a key role of cellular senescence in these biological processes, but in humans the
