Clear cell renal cell carcinoma (ccRCC) is the most common subtype of RCC (70-80%). Yes-associated protein 1 (YAP1) protein is a nuclear effector of the Hippo pathway and acts as a transcriptional co-activator of genes involved in the processes of growth and development of tissues. Hippo signaling, with its key kinases, MST2 and large tumor suppressor kinase 1 (LATS1), plays a significant role in the negative regulation of the amount and activity of YAP1 protein. Components of the Hippo pathway and YAP1 levels are frequently dysregulated in a variety of tumors, suggestive of their possible involvement in carcinogenesis...

Plasma endothelial cell-derived exosomes (EDEs) and platelet-derived exosomes (PDEs) were precipitated and enriched separately by immunospecific absorption procedures for analyses of cargo proteins relevant to atherosclerosis. EDEs had usual exosome size and marker protein content, and significantly higher levels than PDEs of the endothelial proteins vascular cell adhesion molecule-1 (VCAM-1) and endothelial nitric oxide synthase, whereas PDEs had significantly higher levels of platelet glycoprotein VI. EDE levels of VCAM-1, von Willebrand factor, platelet-derived growth factor (PDGF)-BB, angiopoietin-1, and lysyl oxidase-2 and the cerebrovascular-selective proteins glucose transporter 1, permeability-glycoprotein, and large neutral amino acid transporter 1 were significantly higher for 18 patients with cerebrovascular disease (CeVD) than for 18 age- and gender-matched control subjects...

The present study aimed to observe the inhibitory effect and preliminary mechanism of exogenous mammalian sterile 20-like kinase 1 (MST1) on the growth of colorectal cancer SW480 cells. The SW480 cells were randomly divided into the following groups: Control, empty enhanced green fluorescent protein (EGFP) plasmid (pEGFP-N1), MST1 EGFP plasmid (pEGFP-MST1), 20 µmol/l fluorouracil (5-FU) and pEGFP-MST1 + 5-FU. An MTS colorimetric assay was used to detect cell viability, Hoechst 33342 staining was used to observe cell apoptosis, and western blotting and immunohistochemistry were used to detect the levels of the proteins MST1, yes-associated protein (YAP), phospho-YAP1 (Ser127), p53 and p53 upregulated modulator of apoptosis (PUMA)...

FSH mediated cyclic AMP (cAMP) signaling is crucial for function of testicular Sertoli cells (Sc) during puberty. Yes-kinase Associated Protein (YAP), a transcriptional co-activator, regulates cell proliferation and differentiation. However, its role in testicular function is not known. In present study, we have identified YAP as an important regulator of cAMP signaling in Sc, in-vitro. Verteporfin, a YAP-inhibitor, down regulated the expression of cAMP responsive genes necessary for spermatogenesis in Sc. Action of forskolin, which acts via cAMP, was also antagonized by verteporfin, limiting expression of these genes...

The Aurora kinases A and B control tumorigenesis by inhibiting apoptosis and promoting proliferation and metastasis, however, it remains unknown whether Aurora A and B overexpressed concomitantly and its clinical significance in hepatocellular carcinoma (HCC). Here, we obsearved Aurora A and B tended to overexpress parallelly on protein level (r = 0.8679, P < 0.0001) and their co-overexpression (Aurora AHBH), associated with the worst prognosis, was an independent predictor for the survival. Importantly, with the lower IC50 and stronger anti-tumor effect than selective inhibitors, SNS-314, the pan-inhibitor of Aurora kinases, which induced YAP (Yes-associated protein) reduction and resulted in P21 accumulation, significantly promoted the polyploidy (> 4N) formation and apoptosis in HCC...

Background: The efficacy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in EGFR-mutant non-small cell lung cancer (NSCLC) is limited by adaptive activation of cell survival signals. We hypothesized that both signal transducer and activator of transcription 3 (STAT3) and Src-YES-associated protein 1 (YAP1) signaling are dually activated during EGFR TKI treatment to limit therapeutic response. Methods: We used MTT and clonogenic assays, immunoblotting, and quantitative polymerase chain reaction to evaluate the efficacy of EGFR TKI alone and in combination with STAT3 and Src inhibition in three EGFR-mutant NSCLC cell lines...

Recent clinical and experimental evidences strongly acclaim Yes-associated protein (Yap), a key oncogenic driver in liver carcinogenesis, as a therapeutic target. Of the known multiple schemes to inhibit Yap activity, activation of Mammalian Sterile 20-like Kinase 1 (Mst1), an upstream regulator of Yap, appears to be a promising one. In this study, we hypothesize that morin, a bioflavonoid, mediates its anti-cancer effect through the activation of Mst1/hippo signaling in liver cancer cells. To test this hypothesis, both full length Mst1 (F-Mst1) and kinase active N-terminal Mst1 (N-Mst1)-overexpressed HepG2 cells were used...

We examined the impact of crosstalk between the insulin receptor and G protein-coupled receptor (GPCR) signaling pathways on the regulation of Yes-associated protein (YAP) localization, phosphorylation, and transcriptional activity in the context of human pancreatic ductal adenocarcinoma (PDAC). Stimulation of PANC-1 or MiaPaCa-2 cells with insulin and neurotensin, a potent mitogenic combination of agonists for these cells, promoted striking YAP nuclear localization and decreased YAP phosphorylation at Ser(127) and Ser(397) Challenging PDAC cells with either insulin or neurotensin alone modestly induced the expression of YAP/TEAD-regulated genes, including connective tissue growth factor (CTGF), cysteine-rich angiogenic inducer 61 (CYR61), and CXCL5, whereas the combination of neurotensin and insulin induced a marked increase in the level of expression of these genes...

BACKGROUND: Pharmacological inhibition of B cell receptor (BCR) signaling has recently emerged as an effective approach in a wide range of B lymphoid neoplasms. However, despite promising clinical activity of the first Bruton's kinase (Btk) and spleen tyrosine kinase (Syk) inhibitors, a small fraction of patients tend to develop progressive disease after initial response to these agents. METHODS: We evaluated the antitumor activity of IQS019, a new BCR kinase inhibitor with increased affinity for Btk, Syk, and Lck/Yes novel tyrosine kinase (Lyn), in a set of 34 B lymphoid cell lines and primary cultures, including samples with acquired resistance to the first-in-class Btk inhibitor ibrutinib...

Yes-associated protein (YAP) is a transcriptional coactivator in the Hippo pathway that regulates cell proliferation, differentiation, and apoptosis. The MEK5/ERK5 MAPK cascade is essential for the early step of myogenesis. In this study, we generated C2C12 stable cell lines that expressed YAP (C2C12-YAP cells) and found that ERK5 and MEK5 were activated in C2C12-YAP cells compared with control C2C12 (C2C12-vector) cells. C2C12-YAP stable cells also differentiated into myotubes better than C2C12-vector cells, and expressed elevated levels of myogenin, a transcription factor that regulates myogenesis, as well as elevated levels of myosin heavy chain, a skeletal muscle marker...

The binding of Src-homology 2 (SH2) domains to phosphotyrosine (pY) sites is critical for the autoinhibition and substrate recognition of the eight Src family kinases (SFKs). The high sequence conservation of the 120 human SH2 domains poses a significant challenge to selectively perturb the interactions of even the SFK SH2 family against the rest of the SH2 domains. We have developed synthetic binding proteins, termed monobodies, for six of the SFK SH2 domains with nanomolar affinity. Most of these monobodies competed with pY ligand binding and showed strong selectivity for either the SrcA (Yes, Src, Fyn, Fgr) or SrcB subgroup (Lck, Lyn, Blk, Hck)...

In postconfluent human pulmonary microvascular endothelial cell (HPMEC)s, NEU1 sialidase associates with and desialylates the src family kinase (SFK) substrate, CD31, and disrupts angiogenesis. We asked whether the NEU1-CD31 interaction might be SFK-driven. We found that normalized phospho-SFK (PY416) signal is increased in postconfluent HPMECs compared to subconfluent cells and prior SFK inhibition with PP2 or SU6656 completely blocked NEU1 association with and desialylation of CD31. Prior silencing of each of the four SFKs expressed in HPMECs, as well as CD31, dramatically reduced confluence-induced SFK activation...

TEA domain transcription factor 4 (TEAD4), which has critical functions in the process of embryonic development, is expressed in various cancers. However, the important role of TEAD4 in human oral squamous cell carcinomas (OSCCs) remain unclear. Here we investigated the TEAD4 expression level and the functional mechanism in OSCC using quantitative reverse transcriptase-polymerase chain reaction, Western blot analysis, and immunohistochemistry. Furthermore, TEAD4 knockdown model was used to evaluate cellular proliferation, cell-cycle analysis, and the interaction between TEAD4 and Yes-associated protein (YAP) which was reported to be a transcription coactivator of cellular proliferation...

The core components of the Hippo signaling pathway are a cascade of kinases that govern the phosphorylation of downstream transcriptional co-activators, namely, YES-associated protein (YAP) and WW domain-containing transcription regulator protein 1 (WWTR1, also known as TAZ). The Hippo signaling pathway is considered an important tumor-suppressor pathway, and its dysregulation has been noted in a variety of human cancers, in which YAP/WWTR1 enable cancerous cells to overcome contact inhibition, and to grow and spread uncontrollably...

Previous studies showed that the protein kinase B (Akt)-mammalian target of rapamycin (mTOR) and Hippo signaling Yes-associated protein (YAP) pathways play important roles in promoting follicle growth. Additionally, other studies demonstrated that 5' adenosine monophosphate-activated protein kinase (AMPK) is an upstream regulatory element of mTOR and YAP.

During the course of cholestatic liver diseases, mitotically dormant cholangiocytes proliferate and subsequently acquire a neuroendocrine phenotype. Galanin is a neuroendocrine factor responsible for regulation of physiological responses, such as feeding behavior and mood, and has been implicated in the development of fatty liver disease, although its role in biliary hyperplasia is unknown. Biliary hyperplasia was induced in rats via bile duct ligation (BDL) surgery, and galanin was increased in serum and liver homogenates from BDL rats...

The polyomavirus middle T antigen (PyMT) oncogene activates the cellular nonreceptor tyrosine kinase c-Src and recruits the Hippo pathway effectors, Yap (yes-associated protein) and Taz (transcriptional coactivator with PDZ-binding motif), as key steps in oncogenesis. Yap and Taz are transcription coactivators shuttling from the cytoplasm to the nucleus. The Hippo pathway kinase Lats1/2 (large tumor suppressor homolog) reduces Yap/Taz nuclear localization and minimizes their cytoplasmic levels by facilitating their ubiquitination by the E3 ligase SCF(β-TrCP)...

Extracellular matrix (ECM) stiffness regulates the lineage commitment of mesenchymal stem cells (MSCs). Although cells sense ECM stiffness through focal adhesion, how cells sense ECM stiffness and regulate ECM stiffness-dependent differentiation remains largely unclear. In this study, we show that cytoskeletal focal adhesion protein vinculin plays a critical role in the ECM stiffness-dependent adipocyte differentiation of MSCs. ST2 mouse MSCs differentiate into adipocytes and osteoblasts in an ECM stiffness-dependent manner...
