The dishevelled (dsh) gene family encodes cytoplasmic proteins that have been implicated in Wnt/Wingless (Wg) signaling. To demonstrate functional conservation of Dsh family proteins, two mouse homologs of Drosophila Dsh, Dvl-1 and Dvl-2, were biochemically characterized in mouse and Drosophila cell culture systems. We found that treatment with a soluble Wnt-3A leads to hyperphosphorylation of ...

To improve the ability of autonomous navigation for Unmanned Surface Vehicles (USVs), multi-sensor integrated navigation based on Inertial Navigation System (INS), Celestial Navigation System (CNS) and Doppler Velocity Log (DVL) is proposed. The CNS position and the DVL velocity are introduced as the reference information to correct the INS divergence error. The autonomy of the integrated syste...

Dishevelled (DVL) proteins are key mediators of Wnt/β-catenin signaling pathway. All DVL proteins contain three conserved domains -- DIX, PDZ and DEP. There is a consensus in the field that DIX domain is critical for Wnt/β-catenin signaling but contradictory evidence exists regarding the function of the DEP domain. It has been difficult until recently to test the importance of the DEP domain ri...

Axin promotes the phosphorylation of beta-catenin by GSK-3beta, leading to beta-catenin degradation. Wnt signals interfere with beta-catenin turnover, resulting in enhanced transcription of target genes through the increased formation of beta-catenin complexes containing TCF transcription factors. Little is known about how GSK-3beta-mediated beta-catenin turnover is regulated in response to Wnt...

It was previously revealed that Wnt signaling is activated in mesothelioma cells. Although epidermal growth factor receptor (EGFR) is expressed in mesothelioma cells, EGFR-tyrosine kinase inhibitors (TKIs) are not effective for mesothelioma treatment. However, in non-small cell lung cancer, the blocking of Wnt signaling has been identified to enhance the anticancer effect of EGFR-TKIs. To confi...

Dishevelled family proteins are multidomain intracellular transducers of Wnt signals. Ectopically expressed mammalian Dishevelled 2 (Dvl-2) activates downstream signalling and localises to cytoplasmic puncta. It has been suggested that these Dvl-2-containing structures correspond to intracellular vesicles and may be involved in the Wnt signal transduction process. We report that cytoplasmic pun...

One aspect of the function of the beta-arrestins is to serve as scaffold or adapter molecules coupling G-protein coupled receptors (GPCRs) to signal transduction pathways distinct from traditional second messenger pathways. Here we report the identification of Dishevelled 1 and Dishevelled 2 (Dvl1 and Dvl2) as beta-arrestin1 (betaarr1) interacting proteins. Dvl proteins participate as key inter...

OBJECTIVE To evaluate diagnostic utility of Dishevelled-3 (DVL-3) mRNA and δ-catenin mRNA expression in pleural effusions of patients with lung cancer. METHODS DVL-3 mRNA and δ-catenin mRNA levels were assessed by performing RT-PCR on pleural effusion specimens from patients with lung cancer (n = 75) and with lung benign disease (n = 51). RESULTS The expressions of DVL-3 mRNA and δ-catenin ...

Dishevelled (DVL) is associated with axonal microtubules and regulates microtubule stability through the inhibition of the serine/threonine kinase, glycogen synthase kinase 3beta (GSK-3beta). In the canonical WNT pathway, the negative regulator Axin forms a complex with beta-catenin and GSK-3beta, resulting in beta-catenin degradation. Inhibition of GSK-3beta by DVL increases beta-catenin stabi...

Hirschsprung's disease (HSCR) is a congenital disorder characterized by an absence of enteric ganglion cells in the terminal regions of the gut during development. To date, the cause of HSCR remains unclear, although the pathogenesis of this complex disease is hypothesized to be influenced by numerous genetic and environmental factors. Dishevelled‑2 (DVL‑2) is a subtype of the dishevelled prote...
