66-418: A scaffold protein because this Hpo-Sav interaction promotes phosphorylation of Wts. Hpo can also phosphorylate and activate Mats (MOBKL1A/B in mammals), which allows Mats to associate with and strengthen the kinase activity of Wts. Activated Wts can then go on to phosphorylate and inactivate the transcriptional coactivator Yorkie (Yki). Yki is unable to bind DNA by itself. In its active state, Yki binds to

165-407: A fundamental growth control property of normal cells in vitro and in vivo , in which proliferation stops after cells reach confluence (in culture) or occupy maximum available space inside the body and touch one another. This property is typically lost in cancerous cells, allowing them to proliferate in an uncontrolled manner. In fact, YAP overexpression antagonizes contact inhibition. Many of
198-720: A key role of this pathway in regulation of cardiomyocyte proliferation and heart size. Inactivation of the Hippo pathway or activation of its downstream effector, the Yes-associated protein transcription coactivator, improves cardiac regeneration. Several known upstream signals of the Hippo pathway such as mechanical stress, G-protein-coupled receptor signaling, and oxidative stress are known to play critical roles in cardiac physiology. In addition, Yes-associated protein has been shown to regulate cardiomyocyte fate through multiple transcriptional mechanisms. Note that Hippo TAZ protein
231-405: A more nuanced role in cancer than previously thought. Hippo pathway inactivation enhanced the effect of 15 FDA-approved oncology drugs by promoting chemo-retention. In another study, the Hippo pathway kinases LATS1/2 were found to suppress cancer immunity in mice. Not all studies, however, support a role for Hippo signaling in promoting carcinogenesis. In hepatocellular carcinoma , for instance, it
264-658: A positive growth regulator that specifically affects cell number. Thus, the inactivation of Yki by Wts inhibits growth through the transcriptional repression of these pro-growth regulators. By phosphorylating Yki at serine 168, Wts promotes the association of Yki with 14-3-3 proteins , which help to anchor Yki in the cytoplasm and prevent its transport to the nucleus. In mammals, the two Yki orthologs are Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif ( WWTR1, also known as TAZ ). When activated, YAP and TAZ can bind to several transcription factors including p73 , Runx2 and several TEADs. YAP regulates

495-492: Is a nuclear DBF-2-related kinase. These kinases are known regulators of cell cycle progression, growth, and development. Two proteins are known to facilitate the activation of Wts: Salvador (Sav) and Mob as tumor suppressor (Mats). Sav ( SAV1 in mammals) is a WW domain -containing protein, meaning that this protein contains a sequence of amino acids in which a tryptophan and an invariant proline are highly conserved. Hpo can bind to and phosphorylate Sav, which may function as
528-431: Is how an organ knows to stop growing after reaching a particular size. Organ growth relies on several processes occurring at the cellular level, including cell division and programmed cell death (or apoptosis). The Hippo signaling pathway is involved in restraining cell proliferation and promoting apoptosis. As many cancers are marked by unchecked cell division, this signaling pathway has become increasingly significant in
561-673: Is known to interact with Fat1 in human liver cancer. GPC3 is also shown to modulate Yap signaling in liver cancer. While Fat is known to bind to another atypical cadherin, Dachsous (Ds), during tissue patterning, it is unclear what role Ds has in regulating tissue growth. Nevertheless, Fat is recognized as an upstream regulator of the Hpo pathway. Fat activates Hpo through the apical protein Expanded (Ex; FRMD6/Willin in mammals). Ex interacts with two other apically-localized proteins, Kibra ( KIBRA in mammals) and Merlin (Mer; NF2 in mammals), to form
594-490: The Salvador-Warts-Hippo ( SWH ) pathway , is a signaling pathway that controls organ size in animals through the regulation of cell proliferation and apoptosis . The pathway takes its name from one of its key signaling components—the protein kinase Hippo (Hpo). Mutations in this gene lead to tissue overgrowth, or a " hippopotamus "-like phenotype . A fundamental question in developmental biology
627-660: The Hippo pathway. The heart is the first organ formed during mammalian development. A properly sized and functional heart is vital throughout the entire lifespan. Loss of cardiomyocytes because of injury or diseases leads to heart failure, which is a major cause of human morbidity and mortality. Unfortunately, regenerative potential of the adult heart is limited. The Hippo pathway is a recently identified signaling cascade that plays an evolutionarily conserved role in organ size control by inhibiting cell proliferation, promoting apoptosis, regulating fates of stem/progenitor cells, and in some circumstances, limiting cell size. Research indicates
660-558: The Kibra-Ex-Mer (KEM) complex. Both Ex and Mer are FERM domain -containing proteins, while Kibra, like Sav, is a WW domain-containing protein. The KEM complex physically interacts with the Hpo kinase cascade, thereby localizing the core kinase cascade to the plasma membrane for activation. Fat may also regulate Wts independently of Ex/Hpo, through the inhibition of the unconventional myosin Dachs. Normally, Dachs can bind to and promote
693-454: The Ste-20 family of protein kinases. This highly conserved group of serine/threonine kinases regulates several cellular processes, including cell proliferation, apoptosis, and various stress responses. Once phosphorylated, Wts ( LATS1 /2 in mammals) becomes active. Misshapen (Msn, MAP4K4/6/7 in mammals) and Happyhour (Hppy, MAP4K1/2/3/5 in mammals) act in parallel to Hpo to activate Wts. Wts

792-654: The degradation of Wts. In fruitfly, the Hippo signaling pathway involves a kinase cascade involving the Salvador (Sav), Warts (Wts) and Hippo (Hpo) protein kinases . Many of the genes involved in the Hippo signaling pathway are recognized as tumor suppressors , while Yki/YAP/TAZ is identified as an oncogene . YAP/TAZ can reprogram cancer cells into cancer stem cells . YAP has been found to be elevated in some human cancers, including breast cancer , colorectal cancer , and liver cancer . This may be explained by YAP’s recently defined role in overcoming contact inhibition ,

891-535: The pathway components recognized as tumor suppressor genes are mutated in human cancers. For example, mutations in Fat4 have been found in breast cancer, while NF2 is mutated in familial and sporadic schwannomas . Additionally, several human cancer cell lines invoke mutations of the SAV1 and MOBK1B proteins. However, recent research by Marc Kirschner and Taran Gujral has demonstrated that Hippo pathway components may play

Thus, the delineation of the pathway in Drosophila has helped to identify many genes that function as oncogenes or tumor suppressors in mammals.
