Genetic theories of aging propose that aging is programmed within each individual's genes. According to this theory, genes dictate cellular longevity. Programmed cell death, or apoptosis, is determined by a "biological clock" via genetic information in the nucleus of the cell. Genes responsible for apoptosis provide an explanation for cell ...
In general, biological aging clocks and biomarkers of aging are expected to find many uses in biological research since age is a fundamental characteristic of most organisms. Accurate measures of biological age (biological aging clocks) could be useful for testing the validity of various theories of biological aging,
Watching the clock. To test for biological age, ... for example, was about 12 years older than the rest of the body. ... Understanding biological aging can be empowering. But it's just as ...
Circadian clock, a molecular mechanism that results in a circadian rhythm in a living organism; Circadian rhythm, biological process that displays an oscillation about 24 hours, such as the human sleep-wake cycle (the "body clock") Epigenetic clock, a set of DNA sites whose methylation levels can be used to measure aging throughout the body
As women age, ovarian reserve -- which is defined as the quantity and the quality of the eggs remaining in the ovaries -- declines, and when all eggs are depleted, menopause starts and ...
Ageing (or aging in American English) is the process of becoming older. The term refers mainly to humans , many other animals , and fungi, whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal . [ 1 ]
Abdominal fat, for example, was analyzed in 15 study participants. Even so, this research marks an exciting step in the science of aging, Longo tells Fortune , adding that additional FMD trials ...
