Protein homeostasis in aging and cancer

Xiao-Qiong Chen et al. Front Cell Dev Biol. .

Abstract

Aging is a major risk factor for cancer development. As dysfunction in protein homeostasis, or proteostasis, is a universal hallmark of both the aging process and cancer, a comprehensive understanding of the proteostasis system and its roles in aging and cancer will shed new light on how we can improve health and quality of life for older individuals. In this review, we summarize the regulatory mechanisms of proteostasis and discuss the relationship between proteostasis and aging and age-related diseases, including cancer. Furthermore, we highlight the clinical application value of proteostasis maintenance in delaying the aging process and promoting long-term health.

Keywords: aging; autophagy-lysosomal system; cancer; molecular chaperones; protein homeostasis; ubiquitin-proteasome system.

Overview of regulatory mechanisms of protein homeostasis. Long-term chronic stress (e.g., oxidative stress) is an important cause for the loss of protein homeostasis, however, the increase in the function of proteolytic system (i.e., ubiquitin-proteasome system and autophagy-lysosomal system) and repair system (i.e., molecular chaperones) can promote the maintenance of protein homeostasis.
