چکیده

Telomeres, the DNA-protein structures located at the ends of chromosomes, have been proposed to act as a biomarker of aging. In this review, the human evidence that telomere length is a biomarker of aging is evaluated. Although telomere length is implicated in cellular aging, the evidence suggesting telomere length is a biomarker of aging in humans is equivocal. More studies examining the relationships between telomere length and mortality and with measures that decline with "normal" aging in community samples are required. These studies would benefit from longitudinal measures of both telomere length and aging-related parameters.

Is Telomere Length a Biomarker of Adaptive Response? Controversial Findings of NASA and Residents of High Background Radiation Areas

Telomere length and stability is a biomarker of aging, stress, and cancer. Shortening of telomeres and high level of DNA damages are known to be associated with aging. Telomere shortening normally occurs during cell division in most cells and when telomeres reach a critically short length, DNA damage signaling and cellular senescence can be triggered. The induction of an adaptive response by sp...

Telomere length in epidemiology: a biomarker of aging, age-related disease, both, or neither?

Telomeres are nucleoprotein caps flanking DNA. They are shortened by cell division and oxidative stress and are lengthened by the enzyme telomerase and DNA exchange during mitosis. Short telomeres induce cellular senescence. As an indicator of oxidative stress and senescence (2 processes thought to be fundamental to aging), telomere length is hypothesized to be a biomarker of aging. This hypoth...

Effects of Aerobic Training Combined with Green Tea Extract on Leukocyte Telomere Length, Quality of Life and Body Composition in Elderly Women

Background: Exercise and consumption of green tea affect the aging process. However, the effect of exercise training combined with green tea extract on leukocyte telomere length, quality of life (QoL) and body composition in aging has so far been unclear and inconsistent. Objective: The aim of the present study was to determine the effectiveness of aerobic training intervention and green tea e...

Background & objective: Mesenchymal stem cells (MSCs) are presently isolated from various human tissues such as bone marrow. These cells have relatively high replication potential and can differentiate into various cell lineages with mesodermal and non-mesodermal origin and therefore, show promising in treatment of diseases. Their striking features like availability of source, ease of isolation...
