WebThe most popular biomarker of cellular senescence (BCS) is the activity of senescence-associated β-galactosidase (SA-β-Gal). Today, this is the prevailing BCS in the studies … WebSenescence, through a variety of mechanisms, may play a role in tumor suppression, tumor progression, aging, and tissue repair. Activation of β-galactosidase is commonly used as a biomarker for senescent cells. This hydrolase enzyme resides in lysosomes and converts β-galactosides into monosaccharides under acidic pH conditions. Senescence-associated beta-galactosidase (SA-β-gal or SABG) is a hypothetical hydrolase enzyme that catalyzes the hydrolysis of β-galactosides into monosaccharides only in senescent cells. Senescence-associated beta-galactosidase, along with p16 , is regarded to be a biomarker of cellular senescence. Its existence was proposed in 1995 by Dimri et al. following the observation that when beta-galac… hometown logistics tracking
