          Abstract

          The Hippo pathway senses cellular conditions and regulates YAP/TAZ to control cellular and tissue homeostasis, while TBK1 is central for cytosolic nucleic acid sensing and antiviral defense. The correlation between cellular nutrient/physical status and host antiviral defense is interesting but not well understood. Here we find that YAP/TAZ act as natural inhibitors of TBK1 and are vital for antiviral physiology. Independent of transcriptional regulation and through transactivation domain, YAP/TAZ associate directly with TBK1 and abolish virus-induced TBK1 activation, by preventing TBK1 K63-linked ubiquitination and adaptors/substrates binding. Accordingly, YAP/TAZ deletion/depletion or cellular conditions inactivating YAP/TAZ through Lats1/2 kinases relieve TBK1 suppression and boost antiviral responses, whereas expression of the transcriptionally inactive YAP dampens cytosolic RNA/DNA sensing and weakens the antiviral defense in cells and zebrafish. Thus, we describe a function of YAP/TAZ and the Hippo pathway in innate immunity, by linking cellular nutrient/physical status to antiviral host defense.

          Regulation of the Hippo-YAP pathway by G-protein-coupled receptor signaling.

          The Hippo pathway is crucial in organ size control, and its dysregulation contributes to tumorigenesis. However, upstream signals that regulate the mammalian Hippo pathway have remained elusive. Here, we report that the Hippo pathway is regulated by G-protein-coupled receptor (GPCR) signaling. Serum-borne lysophosphatidic acid (LPA) and sphingosine 1-phosphophate (S1P) act through G12/13-coupled receptors to inhibit the Hippo pathway kinases Lats1/2, thereby activating YAP and TAZ transcription coactivators, which are oncoproteins repressed by Lats1/2. YAP and TAZ are involved in LPA-induced gene expression, cell migration, and proliferation. In contrast, stimulation of Gs-coupled receptors by glucagon or epinephrine activates Lats1/2 kinase activity, thereby inhibiting YAP function. Thus, GPCR signaling can either activate or inhibit the Hippo-YAP pathway depending on the coupled G protein. Our study identifies extracellular diffusible signals that modulate the Hippo pathway and also establishes the Hippo-YAP pathway as a critical signaling branch downstream of GPCR.

            Triggering the interferon antiviral response through an IKK-related pathway.

            Rapid induction of type I interferon expression, a central event in establishing the innate antiviral response, requires cooperative activation of numerous transcription factors. Although signaling pathways that activate the transcription factors nuclear factor kappaB and ATF-2/c-Jun have been well characterized, activation of the interferon regulatory factors IRF-3 and IRF-7 has remained a critical missing link in understanding interferon signaling. We report here that the IkappaB kinase (IKK)-related kinases IKKepsilon and TANK-binding kinase 1 are components of the virus-activated kinase that phosphorylate IRF-3 and IRF-7. These studies illustrate an essential role for an IKK-related kinase pathway in triggering the host antiviral response to viral infection.

              Cellular energy stress induces AMPK-mediated regulation of YAP and the Hippo pathway

              YAP (Yes-associated protein) is a transcription co-activator in the Hippo tumor suppressor pathway and controls cell growth, tissue homeostasis, and organ size. YAP is inhibited by the kinase Lats, which phosphorylates YAP to induce its cytoplasmic localization and proteasomal degradation. YAP induces gene expression by binding to the TEAD family transcription factors. Dysregulation of the Hippo-YAP pathway is frequently observed in human cancers. Here we show that cellular energy stress induces YAP phosphorylation, in part due to AMPK-dependent Lats activation, thereby inhibiting YAP activity. Moreover, AMPK directly phosphorylates YAP S94, a residue essential for the interaction with TEAD, thus disrupting the YAP-TEAD interaction. AMPK-induced YAP inhibition can suppress oncogenic transformation of Lats-null cells with high YAP activity. Our study establishes a molecular mechanism and functional significance of AMPK in linking cellular energy status to the Hippo-YAP pathway.
