Abstract:
Aging is one of the most important risk factors for human diseases such as cancer, cardiovascular diseases, diabetes and neurodegenerative diseases, and many aging diseases are related to cellular aging. Cells show profound phenotypic changes during aging, which are driven by changes in metabolism, chromatin organizationand transcriptional activity. A significant feature of aging is the secretion of inflammatory mediators, including various cytokines, chemokines, extracellular matrix proteins and growth factors, collectively known as the aging-related secreted phenotype (SASP). By secreting SASP, senescent cells have important effects on many biological processes, such as wound healing, tissue repair, tumor formation, or in vivo reorganization. In addition, the inflammatory response associated with SASP is considered to be the basis of aging-related diseases, and the discovery of new targets to control the response of aging effects is crucial. Recent scientific advances have shown that innate immune responses, particularly those involving the cGAS-STING pathway, trigger SASP. In this article, we review the biological function and regulatory mechanism of SASP through the cGAS-STING signaling pathway in aging diseases.
