Web16 de abr. de 2015 · There are two major pathways for TAAs proteolysis in the tumor cells. The short-lived proteins (SLiPs), including the defective ribosomal products (DRiPs), are ubiquitinated and degraded by proteasomes [5,6], whereas the long-lived proteins are mostly degraded by the lysosomes through the autophagy pathway [7,8]. Web8 de dez. de 2015 · As mentioned, FOXOs are involved in the proteasome system degradation of short-lived and regulatory cytosolic proteins. Aging is associated with a decreased proteasomal activity, leading to excess of damaged proteins in muscle, liver, and heart (Conconi et al., 1996; Petropoulos et al., 2000; Bulteau et al., 2002; Husom et al., …
