Speaking more specifically, β-catenin is an integral structural component of cadherin-based adhesive junctions as well as it a key nuclear effector of canonical in nucleus Wnt signaling. (chemdiv.com)

Abnormal activation of this pathway plays an essential role in chemoradiotherapy resistance ( 12 ). (frontiersin.org)

In embryonic stem cells, the Wnt signaling pathway promotes the maintenance of pluripotency. (chicagobiomedicalconsortium.org)

Wnt deregulation in brain is associated with congenital disorders [ 7 ], whereas it promotes malignancy in somatic cells of neuronal origin [ 8 ]. (biomedcentral.com)

We focus on novel combinatorial codes for transcription factors as nuclear effectors of major signaling pathways, including Wnt and FGF/MEK signaling. (uibk.ac.at)

Wnt signaling also controls tissue regeneration in adult bone marrow, skin and intestine. (wikipedia.org)
However, the processes underlying tissue renewal and the mechanisms that govern their coordination have proved difficult to study in the human gut. (uea.ac.uk)
In adult tissues, this pathway plays a role in the maintenance and renewal of stem cells, which are cells that help repair tissue damage and can give rise to other types of cells. (medlineplus.gov)

Further analyses seek to define the Wnt signaling mechanisms and are focused on our lab's unique organotypic model of leiomyoma, in which human fibroid tumors are grown in immune-compromised mice. (tufts.edu)

They hypothesized that loss of Wnt activity in microvessel endothelial cells contributes to PAH - and they were right. (stanford.edu)
Ultimately, the investigators not only shed light on a specific signaling pathway that contributes to PAH, but also defined its mechanism of action: reduced Wnt7a signaling decreases the formation of tip cells that are important for repairing blood vessels. (stanford.edu)
These findings collectively point to a role for Islet via Wnt signaling in the maintenance and activation of posterior genes in differentiating blastema cells for tail formation. (riken.jp)
The Wnt signaling pathway creates a complex network of proteins that have different effects on cells, so they can be involved in many cancers, including gliomas. (researchsquare.com)
Also, Quantitative RT-PCR was used to evaluate the mRNA expression level of genes related to the Wnt signal pathway in treated cancer cells and control groups. (researchsquare.com)
The Wnt signaling pathway creates a complex network of proteins that have different effects on cells. (researchsquare.com)
Moreover, PVRL4 triggers a form of signaling between the cells called integrin β4 signaling that allows them to survive without being anchored to the extracellular matrix. (elifesciences.org)
The focus of our research is to understand how autoimmune T cells evade tolerogenic mechanisms and why regulatory T cells fail in autoimmunity. (utah.edu)
Reduced SMO-dependent expression of Gli1 was demonstrated in both Tsc1 −/− and Tsc2 −/− cells, and we found that Tsc1 is required for TGF-β induced phosphorylation of SMAD2/3 and subsequent expression of the HH signaling effector and transcription factor GLI2. (springer.com)
Here we aim to illuminate the underlying molecular mechanisms of LMWH in sensitizing A2780cis cells for cisplatin. (oncotarget.com)
Using TCF/LEF luciferase promotor assay (Top/Flash) we show that resistant A2780cis cells possess a threefold higher Wnt signaling activity compared to A2780 cells. (oncotarget.com)
Hence, LMWH reduces the cisplatin-induced rise in Wnt activity and TCF-4 expression in A2780cis cells, but keeps sensitive A2780 cells unaffected. (oncotarget.com)
Consequently, Wnt signaling pathway appears as primary target of LMWH in sensitizing A2780cis cells for cisplatin toxicity. (oncotarget.com)

This has led to an improved understanding of the multilayered mechanisms of this pathway transduction proceeds as well as the molecular mechanism regulating this pathway ( 28 ). (frontiersin.org)
However, a plausible molecular mechanism connecting CHD and MINK1 is unknown. (xenbase.org)

That is accomplished by transferring factors that modulate different metabolic and signaling pathways. (frontiersin.org)
Wnt signaling pathway has been investigated extensively for its diverse metabolic and pain modulating mechanisms and recently its involvement has been postulated in the development of neuropathic pain. (iasp-pain.org)

Its role in embryonic development was discovered when genetic mutations in Wnt pathway proteins produced abnormal fruit fly embryos. (wikipedia.org)

Wnt comprises a diverse family of secreted lipid-modified signaling glycoproteins that are 350-400 amino acids in length. (wikipedia.org)

The discovery of Wnt signaling was influenced by research on oncogenic (cancer-causing) retroviruses. (wikipedia.org)
Specific oncogenic signals, therefore, can mediate cancer immune evasion and resistance to immunotherapies, pointing to new candidate targets for immune potentiation. (nih.gov)
The overarching goal of the Evason laboratory is to investigate mechanisms involved in liver tumorigenesis in order to develop improved therapies to treat this deadly cancer. (utah.edu)
Understanding the molecular mechanisms underlying Al toxicity might contribute to improve strategies for prevention, early detection, and targeted therapies for the management of colon cancer patients. (bvsalud.org)

Hyperactivation of Wnt and Ras-MAPK signalling are common events in development of colorectal adenomas. (vu.nl)
The major focus of our lab is on innate immunity and inflammation, with projects ranging from molecular mechanisms of signal transduction to translational aspects of drug development. (utah.edu)
Additional screens for MMTV provirus entry sites in tumors revealed several other upregulated genes that are associated with other gene development pathways such as INT2, INT3, and INT4 [4,5,6]. (chemdiv.com)
Wnt signaling is known to be involved in many aspects of development before birth. (medlineplus.gov)

Interestingly, the loss of Islet function had a more limited effect than that of Wnt, in that Djwnt1/P-1(RNAi) worms show both tailless regeneration and occasional formation of two-headed regenerants (known as the Janus-heads phenotype), while Djislet(RNAi) animals regenerated without tails, but never with two heads. (riken.jp)
Interestingly, AURKA has been shown to further enhance Wnt and Ras-MAPK signalling. (vu.nl)
