Absence of Ctf1 is associated with decreased arterial fibrosis, stiffness mad senescence and increased longevity. Ctf1-null mice have a decrease in arterial stiffness and decrease in levels of inflammatory, apoptotic and senescence, whereas telomere-linked and DNA repair proteins as well as antioxidant enzyme activities are increased. The median lifespan of Ctf1-null mice is increased by 5 month (18%) [23172930].

Wild-type and Ctf1-null mice exhibit an increase of senescence markers (p53, Mdm2, p21, and p16) with age but are lower in Ctf1-null mice. Ctf1-null mice have a diminished vascular NFκB signaling, lower inflammation and oxidative stress and reduced senescence. Ctf1-null mice have a 12% increase in body weight, 130% increased adiponectin levels and 51% decreased leptin concentrations [23172930].

Treatment of cells with CT-1 increases SA-β-galactosidase, and apotosis and senescence makers (p53, p21 and p16), without modifying Mdm2 expression [23172930].
