The Role Of Zyxin And Limd1 In Mitosis And Cancer, Jiuli Zhou

The Hippo signaling pathway, originally discovered in Drosophila, consists of a core kinase cascade and has been subsequently demonstrated to control tissue growth and tumorigenesis. The core of this pathway contains MST1/2 (Mammalian sterile 20-like kinase 1/2), LATS1/2 (large tumor suppressor 1/2) and downstream effector named Yes-associated protein (YAP) and PDZ-binding motif (TAZ). MST1/2 transduce their kinase activity mainly through directly phosphorylating LATS1/2. Once phosphorylated and activated, LATS1/2 subsequently phosphorylate and inhibit YAP/TAZ from translocating to nucleus, thereby suppressing the expression of downstream pro-growth and survival genes. While recent studies provide important insight into the tumor suppressor properties of …

The Hippo pathway is conserved regulator of organ size through control of proliferation, apoptosis, and stem-cell self-renewal. In addition to this important function, many of the canonical signaling members have also been shown to be regulated during mitosis. Importantly, Hippo pathway components are frequently dysregulated in cancers and have attracted attention as possible targets for improved cancer therapeutics. Further exploration of Hippo-YAP (yes-associated protein) signaling has revealed new regulators and effectors outside the canonical signaling network and has revealed a larger non-canonical network of signaling proteins in which canonical Hippo pathway components crosstalk with important cellular homeostasis and apoptosis signaling …
