An arrest in cell proliferation, also referred to as cellular senescence, occurs as a natural result of aging and in response to cellular stress. Senescent cells accumulate with age and are associated with many aging phenotypes, ...

One of the main mechanisms the body uses to protect itself against cancer is to switch off defective cells by making them senescent; these cells do not die but stop dividing: their life cycle stops. A team of researchers ...

(Medical Xpress)—One way cells promote tumor suppression is through a process called senescence, an irreversible arrest of proliferation. Senescence is thought to be associated with normal aging, but is also a protective ...

Not only do statins extend lives by lowering cholesterol levels and reducing the risks of cardiovascular disease, but new research in the September 2013 issue of The FASEB Journal suggests that they may extend lifespans as ...

Declining levels of the protein BubR1 occur when both people and animals age, and contribute to cell senescence or deterioration, weight loss, muscle wasting and cataracts. Mayo Clinic researchers have shown that adult progenitor ...

Cell aging, or cellular senescence, has an important role in the natural physiological response to tumor development. Activated oncogenes are able to induce senescence, and recent findings have suggested that oncogene-induced ...

Presence of normal p53, a tumor suppressor gene, instead of a mutated version, makes breast cancer chemotherapy with doxorubicin less effective. The preclinical study led by MD Anderson scientists was published today in the ...
