Role and mechanisms of the NF-ĸB signaling pathway in various developmental processes

Abstract

Since the discovery of the nuclear factor kappa B (NF-ĸB) transcription factor 36 years ago, many studies have linked the NF-ĸB signaling pathway to pathological and physiological processes, such as inflammation, immune response, and tumorigenesis. However, as the NF-ĸB signaling pathway is evolutionarily conserved from flies to humans, an increasing number of studies have focused on the impact of NF-ĸB signaling on developmental processes. While our understanding of the mechanisms underlying NF-ĸB signaling involved in tissue and organ development is limited, the numerous studies conducted in recent years have provided preliminary insights into these molecular mechanisms. In this review, we summarize the latest information on the molecular mechanisms behind NF-ĸB signaling involved in tissue and organ development, highlighting the role and significance of the NF-ĸB signaling pathway in developmental processes. This review elucidates the fact that the development of nearly all tissues is associated with NF-ĸB signaling, either directly or indirectly.
