Co-ordination of cell proliferation, differentiation, and apoptosis maintains tissue development and homeostasis under normal or stress conditions. Recently, the highly conserved Hippo signaling pathway, discovered in Drosophila melanogaster and mammalian system, has been implicated as a key regulator of organ size control. Importantly, emerging evidence suggests that Hippo pathway is involved in the responses to cellular stresses, including mechanic stress, DNA damage, and oxidative stress, to maintain homeostasis at the cellular and organic levels. The mutation or deregulation of the key components in the pathway will result in degenerative disorder, developmental defects, or tumorigenesis. The purpose of this review is to summarize the recent findings and discuss how Hippo pathway responds to cellular stress and regulates early development events, tissue homeostasis as well as tumorigenesis.
