  2. CRISPR gene editing - Wikipedia

    en.wikipedia.org/wiki/CRISPR_gene_editing

    CRISPR gene editing (CRISPR, pronounced / ˈ k r ɪ s p ə r / (crisper), refers to a clustered regularly interspaced short palindromic repeats") is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified.

  3. Cellular senescence - Wikipedia

    en.wikipedia.org/wiki/Cellular_senescence

    Biomarkers of cellular senescence have been shown to accumulate in tissues of older individuals. [77] The accumulation of senescent cells in tissues of vertebrates with age is thought to contribute to the development of ageing-related diseases , including Alzheimer's disease , Amyotrophic lateral sclerosis , endocrine disorders including type 2 ...

    en.wikipedia.org/wiki/Genetic_engineering_techniques

    If the position of the gene can be determined using molecular markers then chromosome walking is one way to isolate the correct DNA fragment. If the gene expresses close homology to a known gene in another species, then it could be isolated by searching for genes in the library that closely match the known gene.

    These conditions become more common as humans grow older and include diseases related to aging, such as dementia, cancer and heart disease. Amount of free radicals in the cell can be reduced with help of antioxidants. But there's a problem that some free radicals are used by organism as signal molecules, and too active general reduction of free ...

  6. Free-radical theory of aging - Wikipedia

    en.wikipedia.org/wiki/Free-radical_theory_of_aging

    The free radicals produced in such reactions often terminate by removing an electron from a molecule which becomes changed or cannot function without it, especially in biology. Such an event causes damage to the molecule, and thus to the cell that contains it (since the molecule often becomes dysfunctional).

  7. Senescence - Wikipedia

    en.wikipedia.org/wiki/Senescence

    Senescence (/ s ɪ ˈ n ɛ s ə n s /) or biological aging is the gradual deterioration of functional characteristics in living organisms. Whole organism senescence involves an increase in death rates or a decrease in fecundity with increasing age, at least in the later part of an organism's life cycle.

    A new study out of Penn State suggests that even light activity—like walking or doing chores—can make your brain four years younger. Here's what to know.

  9. Epigenetic clock - Wikipedia

    en.wikipedia.org/wiki/Epigenetic_clock

    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,
