Studies reported that miR-590-3p was involved in human cancer progression. However, its roles of oncogene or anti-oncogene in malignancies still remain elusive. This study was aimed to investigate the effect of miR-590-3p on the cell proliferation and metastasis via Hippo pathway in colorectal cancer (CRC). In our study, miR-590-3p was demonstrated highly expressed in CRC tissues, compared with adjacent normal tissues (P<0.05). In addition, miR-590-3p was positively associated with TNM stage and distant metastasis...

Rhabdomyosarcoma (RMS), a cancer characterized by skeletal muscle features, is the most common soft tissue sarcoma of childhood. While low and intermediate-risk groups have seen improved outcomes, high-risk patients still face a 5-year survival of <30%, a statistic that has not changed in over 40 years. Understanding the biologic underpinnings of RMS is critical. The developmental pathways of Notch and YAP have been identified as potent but independent oncogenic signals that support the embryonal variant of RMS (eRMS)...

The mammalian heart undergoes maturation during postnatal life to meet the increased functional requirements of an adult. However, the key drivers of this process remain poorly defined. We are currently unable to recapitulate postnatal maturation in human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs), limiting their potential as a model system to discover regenerative therapeutics. Here, we provide a summary of our studies, where we developed a 96-well device for functional screening in human pluripotent stem cell-derived cardiac organoids (hCOs)...

BACKGROUND & AIMS: Aberrant expression of microRNAs is associated with many cancers progression. Many studies have shown that miR-16 is down-regulated in many cancers. However, its role in cholangiocarcinoma (CCA) is unknown. METHODS: Quantitative real-time PCR (qRT-PCR) was developed to measure miR-16 expression in CCA tissues and cell lines. CCK-8, colony formation and transwell assays were used to reveal the role of miR-16 in CCA cell proliferation and malignant transformation in vitro...

The transcription factor YAP1 is a major effector of the tumor suppressive Hippo signaling pathway and is also necessary to maintain pluripotency in embryonic stem cells. Elevated levels of YAP1 expression antagonize the tumor suppressive effects of the Hippo pathway, that normally represses YAP1 function. High YAP1 expression is observed in several types of human cancers and is particularly prominent in cancer stem cells. The stem cell transcription factor Sox2, which marks and maintains cancer stem cells in osteosarcomas, promotes YAP1 expression by binding to an intronic enhancer element and YAP1 expression is also crucial for the maintainance of osteosarcoma stem cells...

This study aimed to evaluate the effects of dietary energy restriction on postnatal liver development in Hu sheep ram lambs. A total of 16 ram lambs were randomly divided into two groups: 100% energy requirements diet and 55% energy requirements diet, which were fed for 75 d. Results showed that the final body and liver weights decreased with energy restriction (p <0.05). Energy restriction caused a significant decrease in the levels of circulating insulin-like growth factor 1 (IGF1) and an increase in growth hormone secretion (p <0...

Altered energy metabolism is a universal property of most cancer cells. The Hippo signaling pathway and its principal downstream effector YAP1 are responsible for tissue homeostasis including organ size, cell proliferation, apoptosis, and differentiation. Dysregulation of the Hippo pathway leads to the activation of YAP1 and further culminates in the development of multiple human cancers. In this study, by loss-of-function assay, we demonstrated that YAP1 contributed to the glycolytic phenotype of breast cancer cells...

Angiomotin (AMOT) promotes angiogenesis and plays a role in neovascularization during tumorigenesis. Recently, the AMOT isoform, AMOT-p130, was shown to exert a regulatory effect on Yes-associated protein 1 (YAP1), a major downstream effector of the Hippo pathway. The specific roles of AMOT-p130 and YAP1 in advanced gastric cancer (AGC) are yet to be established. In this study, a total of 166 patients with AGC were enrolled, and AMOT-p130 and YAP1 levels were analyzed by immunohistochemistry using tissue microarrays...

Spatiotemporally ordered production of cells is essential for brain development. Normally, most undifferentiated neural progenitor cells (NPCs) face the apical (ventricular) surface of embryonic brain walls. Pathological detachment of NPCs from the apical surface and their invasion of outer neuronal territories, i.e., formation of NPC heterotopias, can disrupt the overall structure of the brain. Although NPC heterotopias have previously been observed in a variety of experimental contexts, the underlying mechanisms remain largely unknown...

Genomics-driven cancer therapeutics has gained prominence in personalized cancer treatment. However, its utility in indications lacking biomarker-driven treatment strategies remains limited. Here we present a "phenotype-driven precision-oncology" approach, based on the notion that biological response to perturbations, chemical or genetic, in ex vivo patient-individualized models can serve as predictive biomarkers for therapeutic response in the clinic. We generated a library of "screenable" patient-derived primary cultures (PDCs) for head and neck squamous cell carcinomas that reproducibly predicted treatment response in matched patient-derived-xenograft models...

Medullary thyroid cancer (MTC) is a tumor marked by an indolent growth for which few prognostic factors and therapeutic strategies are actually available. Different studies have recently appraised well-differentiated thyroid cancers are characterized by a dysregulation in different microRNA sets; however, only few of them investigated the role of miRNA expression in MTCs. In this study, we have assessed the miR-375 expression in a series of 130 MTCs (104 are sporadic and 26 familial) with a median follow-up of 39 months (range 1-138) and then we have correlated our results with the clinical-pathological features and the patients' outcome...

INTRODUCTION: While lung cancer is generally thought to be environmentally provoked, anecdotal familial clustering has been reported suggesting there may be genetic susceptibility factors. We systematically tested whether germline mutations in eight candidate genes may be risk factors for lung adenocarcinoma. METHODS: We studied lung adenocarcinoma cases for whom germline sequence data had been generated as part of The Cancer Genome Atlas (TCGA) project, but that had not been previously analyzed...

Thrombocytosis is present in more than 30% of patients with solid malignancies and correlates with worsened patient survival. Tumor cell interaction with various cellular components of the tumor microenvironment including platelets is crucial for tumor growth and metastasis. Although it is known that platelets can infiltrate into tumor tissue, secrete pro-angiogenic and pro-tumorigenic factors and thereby increase tumor growth, the precise molecular interactions between platelets and metastatic cancer cells are not well understood...

YAP1, which encodes the Yes-associated protein 1, is part of the Hippo pathway involved in development, growth, repair and homeostasis. Nonsense YAP1 mutations have been shown to co-segregate with autosomal dominantly inherited coloboma. Therefore, we screened YAP1 for variants in a cohort of 258 undiagnosed UK patients with developmental eye disorders, including anophthalmia, microphthalmia and coloboma. We identified a novel 1 bp deletion in YAP1 in a boy with bilateral microphthalmia and bilateral chorioretinal coloboma...

It has recently been shown that miR-622 plays a tumor suppressive role in many human cancers. However, the exact function and underlying mechanism are still unknown. Here, we reported that the level of miR-622 is clearly reduced in human glioma tissues in comparison with normal brain tissues and is negatively correlated with the histological grades. Additionally, ectopically expressed miR-622 significantly inhibited cell proliferation and induced cell cycle arrest at the G0/G1 phase in glioma cells. Furthermore, the bioinformatics analysis revealed that YAP1 possesses putative miR-622 -binding sites within its 3'UTR...

Fibroblast growth factor 8 (FGF8), a member of the fibroblast growth factor (FGF) family, is upregulated in several human cancers, including HCC (HCC). Previous studies have demonstrated that FGF8 increased cell growth and invasion of tumor cells. In the present study we investigated whether FGF8 is involved in the cell proliferation and resistance to several drugs in human HCC cells. We stably overexpressed FGF8 by lentiviral transfection. In addition, we also added recombinant FGF8 instead of stably overexpressing FGF8 in human HCC cells...

Bladder cancer (BC) is one of the most common cancers worldwide with a high progression rate and poor prognosis. The Hippo signalling pathway is a conserved pathway that plays a crucial role in cellular proliferation, differentiation and apoptosis. Furthermore, dysregulation and/or malfunction of the Hippo pathway is common in various human tumours, including BC. In this review, an overview of the Hippo pathway in BC and other cancers is presented. We focus on recent data regarding the Hippo pathway, its network and the regulation of the downstream co-effectors YAP1/TAZ...

SMYD3 is a member of the SET and myeloid-Nervy-DEAF-1 (MYND) domain-containing protein family of methyltransferases, which are known to play critical roles in carcinogenesis. Expression of SMYD3 is elevated in various cancers, including esophageal squamous cell carcinoma (ESCC), and is correlated with the survival time of patients with ESCC. Here, we dissect gene expression data, from a previously described KYSE150 ESCC cell line in which SMYD3 had been knocked down, by integration with the protein-protein interaction (PPI) network, to find the new potential biological roles of SMYD3 and subsequent target genes...

Multidrug resistance (MDR) due to overexpression of P-glycoprotein (P-gp) is a major obstacle that hinders the treatment of hepatocellular carcinoma (HCC). It has been shown that miR-375 inhibits P-gp expression via inhibition of astrocyte elevated gene-1 (AEG-1) expression in HCC, and induces apoptosis in HCC cells by targeting AEG-1 and YAP1. In this study, we prepared lipid-coated hollow mesoporous silica nanoparticles (LH) containing doxorubicin hydrochloride (DOX) and miR-375 (LHD/miR-375) to deliver the two agents into MDR HCC cells in vitro and in vivo...
