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.
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 ...
Senescent cells are usually larger than non-senescent cells. [40] Transformation of a dividing cell into a non-dividing senescent cell is a slow process that can take up to six weeks. [40] Senescent cells affect tumor suppression, wound healing and possibly embryonic/placental development, and play a pathological role in age-related diseases. [20]
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.

One’s biological age, which measures the body’s physiological state, may help predict who is at risk for developing colon polyps, a known risk factor for colorectal cancer.
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.
There was also a gender gap, with women experiencing more years in poor health than men. "Worldwide, women live longer than men, but exhibit a 2.4-year-wider healthspan-lifespan gap," said Terzic.
