Reactive Oxygen Species (ROS) is considered as the main factor of the Free Radical theory of aging over centuries and it indicates the pathophysiology of aging in mammals. ROS causes oxidative stress, which is a major component in the aging process of higher organisms. ROS also leads to many age-related diseases such as cancer, cardiovascular disease, diabetes, etc. ROS causes damage to most of the biological membranes that cause these chronic diseases. Enhanced ROS levels at the cellular level lead to cellular senescence. It is a stage of cells where growth arrest happens associated with the secretion of Senescence-associated secretory phenotype (SASP) factors. Senescence maintains tissue homeostasis, functions in normal development and restricts tumor development. In this regard, recent experimental evidence has shown that the genetic or pharmacological ablation of senescent cells extends the life span and improves the healthspan. Here, we review the cellular and molecular links between cellular senescence and aging and discuss the novel therapeutic avenues that this connection opens.
