Many downstream gene targets of the canonical Wnt/beta-catenin pathway have been identified http://www.stke.org . (biomedcentral.com)
Wnts in this functional class activate the canonical Wnt/beta-catenin pathway (Wnt-1, -3A, and -8). (biomedcentral.com)

Supporting differences in Wnt signaling, gain of function of Wnt-1 in C57mg mouse mammary epithelial cells leads to their morphological transformation while loss of function of Wnt-5a leads to the same transformation. (biomedcentral.com)

Studies have shown that the Wnt/β-catenin signaling pathway controls cell fate and function through the transcriptional and post-translational regulation of omics networks. (frontiersin.org)

During growth, development and disease, extracellular signals are communicated, or transduced, into the cell and in such a way as to elicit a particular cellular response. (biomedcentral.com)

Recently, it was revealed that the ordered localization of proteins and nucleic acids in the membraneless intracellular microenvironment is modulated by liquid-liquid phase separation (LLPS) ( Shin and Brangwynne, 2017 ). (aspetjournals.org)

But it is becoming increasingly clear that protein subcellular localization can be extremely dynamic, allowing key proteins to play different roles in different compartments. (biomedcentral.com)

These findings define a molecular mechanism underlying a tumor-promoting function of thymosin β4 through activation of MRTF/SRF signaling. (aacrjournals.org)
In a non-canonical activation pathway, the MAP3K14-activated CHUK/IKKA homodimer phosphorylates NFKB2/p100 associated with RelB, inducing its proteolytic processing to NFKB2/p52 and the formation of NF-kappa-B RelB-p52 complexes. (cusabio.com)

Activated Notch1 could also block endocrine development and gene expression induced by NeuroD. (biomedcentral.com)

Dsh relays complex Wnt signals in tissues and cells, in normal and abnormal contexts. (wikipedia.org)
however, nuclear accumulations of pSMAD2-C and CLDN3 redistribution were observed with similar time course in ciliated and non-ciliated cells. (springer.com)
Fig. 1: Cellular sources, target cells, signalling and downstream effects of IL-12. (nature.com)
These Wnts were chosen since previous studies suggest that C57mg cells respond differently to these Wnts, and since these Wnts can activate different signaling pathways in other systems. (biomedcentral.com)
The Wnt signaling pathway creates a complex network of proteins that have different effects on cells. (researchsquare.com)
MW) chemicals interact with host cells and molecules and In our daily life, we are confronted with a plethora of natural influence biologic processes such as signal transduction. (cdc.gov)

The results show that the combination of TMZ and KC7F2 can be a promising anti-cancer agent for the treatment of glioblastoma through the Wnt / β-catenin signaling pathway. (researchsquare.com)
