Project description:The Hippo signaling pathway is evolutionarily well conserved, and all core components have one or more mammalian orthologs, including MST1/2 (Hippo), SAV1 (Salvador), LATS1/2 (Warts), MOB1 (Mats), YAP1/TAZ (Yorkie), and TEAD1/2/3/4 (Scalloped) (Halder and Johnson, 2011; Pan, 2007; Dong et al., 2007; Saucedo and Edgar, 2007). When Hippo signaling is active, YAP1/TAZ is phosphorylated by LATS1/2 and sequestered by 14-3-3 proteins in cytoplasm. When Hippo signaling is absent, unphosphorylated YAP1/TAZ enters the nucleus and increases transcriptional activation of genes involved in cell proliferation and survival. The indispensability of the Hippo pathway in restricting cell growth and proliferation has prompted speculation that many members of the pathway might be involved in tumorigenesis. To see the effect of YAP1 and TAZ in HCC cell, we generated gene expression profile.

Project description:Promoting rumen development is closely related to the health and efficient growth of ruminants. In the present study, we aimed to assess the impact of YAP1/TAZ on RE proliferation. The transcriptomic expression was analyzed to investigate the potential regulatory networks. The results indicated that GA promoted RE cell proliferation, while VP disrupted RE cell proliferation. The Hippo, Wnt, and calcium signaling pathways were altered in cells following the regulation of YAP1/TAZ. Upon YAP1/TAZ activation through GA, the CCN1/2 increased to promote RE cell proliferation. While when the YAP1/TAZ was inhibited by VP, the BIRC3 decreased to suppress RE cell proliferation. Thus, YAP1/TAZ may be potential targets for regulating RE cell proliferation. These findings broaden our understanding of the role of YAP1/TAZ and their regulators in RE and offer a potential target for promoting rumen development.

Project description:In order to investigate the effect of Hippo pathway in pancreatic endorince specification and differentiaion, single nucleus RNA seq was performed using mouse pancreatic tissues with Lats1&2 deletion in NGN3+ cells (NL mice). Wild type mice pancreatic tissues were also subject to same analysis as a control.

Project description:Transcriptional co-activators YAP1-TAZ of Hippo signalling in doxorubicin-induced cardiomyopathy

Project description:The Hippo pathway downstream effectors, Yap and Taz, play key roles in cell proliferation and tissue growth, regulating gene expression especially via interaction with Tead transcription factors. To investigate their role in skeletal muscle stem cells, we analysed gene expression changes driven by Taz and compared these to Yap mediated changes to the transcriptome by measurement of gene expression on Affymetrix microarrays. To interrogate overlapping and unique transcriptional changes driven by these Hippo effectors, satellite cell-derived myoblasts were transduced with constitutively active TAZ S89A or YAP S127A retrovirus for 24h or 48h, with empty retrovirus as control. Triplicate microarray analyses of empty vector controls, hYAP1 S127A and TAZ S89A transgenic primary myoblasts were conducted.

Project description:Aims: Hippo signalling is an evolutionarily conserved pathway that controls organ size by regulating apoptosis, cell proliferation and stem cell self-renewal. Recently, the pathway has been shown to exert powerful growth regulatory activity in cardiomyocytes. However, the functional role of this stress- and cell death-related pathway in the human heart and cardiomyocytes is not known. In this study, we investigated the role of the transcriptional co-activators of Hippo signalling, YAP and TAZ, in human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) in response to cardiotoxic agents and investigated the effects of modulating the pathway on cardiomyocyte function and survival. Methods and Results: RNA sequencing analysis of human heart samples with doxorubicin-induced end-stage heart failure and healthy controls showed YAP and ERBB2 (HER2) as upstream regulators of differentially expressed genes correlated with doxorubicin treatment. Thus, we tested the effects of doxorubicin and/or small molecule inhibitor lapatinib on hiPSC-CM in vitro . Using an automated high contentscreen of 96 clinically relevant chemotherapeutic drugs, we showed that doxorubicin induced the highest activation of YAP/TAZ nuclear translocation in both hiPSC-CM and control MCF7 breast cancer cells. The overexpression of YAP rescued doxorubicin- induced cell loss in hiPSC-CM by inhibiting apoptosis and inducing proliferation. In contrast, silencing of YAP and TAZ by siRNAs resulted in elevated mitochondrial membrane potential loss in response to doxorubicin. Human iPSC-CM calcium transients did not change in response to YAP/TAZ silencing. Conclusions: Our results suggest that Hippo signalling is involved in clinical anthracycline-induced cardiomyopathy. Modelling with hiPSC-CM in vitro showed similar responses to doxorubicin as adult cardiomyocytes and revealed a potential cardioprotective effect of YAP in doxorubicin-induced cardiotoxicity.

Project description:The Hippo pathway functions as a tumor-suppressor pathway in human cancers, while the dys-function of Hippo pathway is frequently observed in malignancies. Although the YAP/TAZ activity is tightly controlled by the phosphorylation cascade of MST-LATS-YAP/TAZ axis, it is still unclear why YAP/TAZ protein is activated in human cancers, even Hippo pathway is still active. Besides phosphorylation, recent studies implicate that several post-translational modifications also play critical roles in modulating TAZ function, including ubiquitination. Here, by a DUB (Deubiquitinases) siRNA screening library, we discovered DUB1 as a critical modulator to facilitate gastric cancer stemness and progression, which deubiquitinated and activated TAZ protein. We also identified DUB1 was elevated in gastric cancer, which correlated with TAZ activation and poor survival. DUB1 associated with TAZ protein and deubiquitinated TAZ at several lysine sites, which subsequently stabilized and facilitated TAZ function. Our study revealed a novel deubiquitinase of Hippo/TAZ axis and one possible therapeutic target for Hippo-driven gastric cancer.

Project description:Proper lung function relies on precisely balanced numbers of specialized epithelial cell types that work together and are maintained in homeostasis. We describe essential roles for the transcriptional regulators Yap and Taz, which are key effectors of Hippo pathway signaling, in maintaining lung epithelial homeostasis. We report that conditional deletion of Yap1/Yap and Wwtr1/Taz in the lung epithelium of adult mice results in severe defects with consequent animal lethality. Phenotypes associated with Yap/Taz deletion include alveolar defects and a striking development of goblet cell metaplasia throughout the airways. We performed gene expression analysis of wild type and Yap/Taz null primary mouse airway epithelial cells in order to define Yap/Taz controlled gene expression.

Project description:The Hippo pathway plays an important role in regulating tissue homeostasis, and its effectors YAP and TAZ are responsible for mediating the vast majority of its physiological functions. Although YAP and TAZ are thought to be largely redundant and similarly regulated by Hippo signaling, they have developmental, structural, and physiological differences which suggest there may be differences in their regulation and downstream functions. To better understand the functions of YAP and TAZ in the Hippo pathway, we generated knockout cells and evaluated them in response to many conditions and stimuli. Here, we used RNA-seq to identify and compare differences in the transcriptional profiles between the YAP and TAZ.
