Background: Hepatocellular carcinoma (HCC) remains one of the most lethal cancers. MicroRNA-155 (miR-155) and collagen triple helix repeat containing 1 (CTHRC1) were found to be involved in hepatocarcinogenesis, but their detailed functions in HCC are unclear. Here, we aimed to investigate the underlying role of miR-155-5p and CTHRC1 in HCC. Methods: miR-155-5p and CTHRC1 expression levels were detected by qRT-PCR, IHC and WB in HCC patients and cell lines. Dual-luciferase assay, qRT-PCR and WB were used to validate the target interaction between miR-155-5p and CTHRC1...

Slit-Robo GTPase-activating protein 1 (SRGAP1) functions as a GAP for Rho-family GTPases and downstream of Slit-Robo signaling. We aim to investigate the biological function of SRGAP1 and reveal its regulation by deregulated microRNAs (miRNAs) in gastric cancer (GC). mRNA and protein expression of SRGAP1 were examined by quantitative reverse transcription PCR (qRT-PCR) and western blot. The biological role of SRGAP1 was demonstrated through siRNA-mediated knockdown experiments. The regulation of SRGAP1 by miR-340 and miR-124 was confirmed by western blot, dual luciferase activity assays and rescue experiments...

The diversity of fin morphology within and across fish taxa offers great, but still largely unexplored, opportunities to investigate the proximate mechanisms underlying fin shape variation. Relying on available genetic knowledge brought forth mainly by the comprehensive study of the zebrafish caudal fin, we explored candidate molecular mechanisms for the maintenance and formation of the conspicuously elongated filaments adorning the unpaired fins of the East African "princess cichlid" Neolamprologus brichardi...

Pancreatoblastoma (PBL) is a rare pediatric pancreatic malignancy for which the molecular pathogenesis is not understood. In this study, we report the findings of an integrated multi-omics study of whole exome and RNA sequencing as well as genome-wide copy number and methylation analyses of 10 PBL cases. The PBL genome was characterized by a high frequency of aberrant activation of the Wnt signaling pathway, either via somatic mutations of CTNNB1 (90%) and copy-neutral loss of heterozygosity (CN-LOH) of APC (10%)...

This review describes the molecular alterations observed in the various types of tumors of the adrenal cortex, excluding Conn adenomas, especially the alterations identified by genomic approaches these last five years. Two main forms of bilateral adrenocortical tumors can be distinguished according to size and aspect of the nodules: primary pigmented nodular adrenal disease (PPNAD) which can be sporadic or part of Carney complex, and primary bilateral macro nodular adrenal hyperplasia (PBMAH). The bilateral nature of tumors suggests the existence of an underlying genetic predisposition...

BACKGROUND: Annexin-1 (ANXA1) plays pivotal roles in regulating various physiological processes including inflammation, proliferation and apoptosis, and deregulation of ANXA1 functions has been associated with tumorigenesis and metastasis events in several types of cancer. Though ANXA1 levels correlate with breast cancer disease status and outcome, its distinct functional involvement in breast cancer initiation and progression remains unclear. We hypothesized that ANXA1-responsive kinase signaling alteration and associated phosphorylation signaling underlie early events in breast cancer initiation events and hence profiled ANXA1-dependent phosphorylation changes in mammary gland epithelial cells...

Pluripotent stem cells have demonstrated the potential to generate large numbers of functional cardiomyocytes (CMs) from different cell sources. Besides Wnt signaling, additional pathways are involved in early cardiac development and function. To date however, no study exists showing the effects of perturbing the canonical Wnt pathway using non-human primate embryonic stem (ES) cells. Here we investigated the effect of canonical Wnt inhibition during differentiation of non-human primate ES cell-derived CMs under defined, growth factors conditions...

β-catenin is a central component of adherent junctions and a key effector of canonical Wnt signalling, in which dephosphorylated Ser/Thr β-catenin regulates gene transcription. β-catenin phosphorylation at Tyr142 (PTyr142 β-catenin), which is induced by receptor and Src family Tyr kinases, represents a previously described β-catenin switch from adhesive to migratory roles. In addition to classical β-catenin roles, phosphorylated Ser/Thr β-catenin and total β-catenin were involved in centrosomal functions, including mitotic spindle formation and centrosome separation...

BACKGROUND: 1-hexylcarbamoyl-5-fluorouracil (HCFU), also known as carmofur, is an effective chemotherapeutic agent applied to several cancers. This study was aimed to explore the functional effects of HCFU on cervical cancer cells and tried to uncover its possible mechanism. METHODS: Two immortalized cervical cancer cell lines (HeLa and Caski) and primary cervical cancer cells prepared from two cervical cancer patients were used in this study. Cell viability, apoptosis, colony formation, migration, invasion, and the expressions of cell growth- and metastasis-associated factors were respectively assessed following 0-1 µg/mL of HCFU treatment for 0-48 h...

Bcl-2 homologous antagonist/killer (BAK1) is a critical regulator of mitochondrial apoptosis. Although upregulation of BAK1 induces apoptosis has been established, the underlying molecular mechanism is far from clear. 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS), an organic anion used as a blocker of anion exchangers and chloride channels, has been proved to rescue cell apoptosis both in vitro and in vivo. However, whether DIDS can inhibit BAK1-induced mitochondrial apoptosis remains undefined. Thus, this study aimed to explore whether DIDS could protect BAK1-induced apoptosis through GSK3β/β-catenin signaling pathway...

Head and neck squamous cell carcinoma (HNSCC) is a highly morbid disease. Recent developments including Food and Drug Administration (FDA) approved molecular targeted agent's pembrolizumab and cetuximab show promise but did not improve the five-year survival which is currently less than 40%. The hepatocyte growth factor receptor; also known as mesenchymal-epithelial transition factor (c-Met) and its ligand hepatocyte growth factor (HGF) are overexpressed in head and neck squamous cell carcinoma (HNSCC); and regulates tumor progression and response to therapy...

Investigating the influence of acupuncture on cellular signal transduction is an efficient pathway to reveal the action mechanism of acupuncture on spinal cord injury (SCI). In this study, the experiment research literature regarding acupuncture for SCI during past 10 years was reviewed and analyzed. As a result, it was found that acupuncture could regulate the expression of the first intercellular messenger as well as the second signal molecules including cyclic adenosine monophosphate, cyclic guanosine monophosphate, Ca2+, nitric oxide to intervene the apoptotic signaling pathway, Rho/Rock signaling pathway, Wnt signaling pathway, MAPK signaling pathway, Notch signaling pathway, etc...

Dipeptidyl peptidase-4 inhibitors, such as saxagliptin, have been reported to have beneficial effects on β-cell function, but the specific underlying mechanism remains unclear. Stromal cell-derived factor-1α (SDF-1α), a chemokine produced in multiple organs, has been considered as a crucial regulator in promoting β-cell survival. Here, we speculate that SDF-1α might mediate the effect of saxagliptin on improving β-cell function. After 12-week saxagliptin treatment in high-fat diet/streptozotocin-induced diabetic rats, significant improvement in pancreas insulin secretion capacity evaluated by hyperglycemia clamp and increased β-cell to α-cell areas ratio were observed...

Angiogenesis is an important adaptation mechanism of the blood vessels to the changing requirements of the body during development, aging, and wound healing. Angiogenesis allows existing blood vessels to form new connections or to reabsorb existing ones. Blood vessels are composed of a layer of endothelial cells (ECs) covered by one or more layers of mural cells (smooth muscle cells or pericytes). We constructed a computational Boolean model of the molecular regulatory network involved in the control of angiogenesis...

The role of canonical Wnt/β-catenin signaling in postnatal bone growth has not been fully defined. In the present studies, we generated β-catenin conditional knockout (KO) mice and deleted β-catenin in Col2-expressing chondrocytes and mesenchymal progenitor cells. Findings from analyzing the β-cateninCol2CreER KO mice revealed severe bone destruction and bone loss phenotype in epiphyseal bone, probably due to the increase in osteoclast formation and the accumulation of adipocytes in this area. In addition, we also found bone destruction and bone loss phenotype in vertebral bone in β-cateninCol2CreER KO mice...

The accumulation of visceral adiposity is strongly associated with systemic inflammation and increased cardiometabolic risk. WNT5A, a non-canonical WNT ligand, has been shown to promote adipose tissue inflammation and insulin resistance in animal studies. Among other non-canonical pathways, WNT5A activates planar cell polarity (PCP) signaling. The current study investigated the potential contribution of non-canonical WNT5A/PCP signaling to visceral adipose tissue (VAT) inflammation and associated metabolic dysfunction in individuals with obesity...

Sclerostin has traditionally been thought of as a local inhibitor of bone acquisition that antagonizes the profound osteoanabolic capacity of activated Wnt/β-catenin signaling, but serum sclerostin levels in humans exhibit a correlation with impairments in several metabolic parameters. These data, together with the increased production of sclerostin in mouse models of type 2 diabetes, suggest an endocrine function. To determine whether sclerostin contributes to the coordination of whole-body metabolism, we examined body composition, glucose homeostasis, and fatty acid metabolism in Sost-/- mice as well as mice that overproduce sclerostin as a result of adeno-associated virus expression from the liver...
