The canonical Wnt signaling pathway controls normal embryonic development, cellular proliferation and growth, and its aberrant activity results in human carcinogenesis. The core component in regulation of this pathway is β-catenin, but molecular regulation mechanisms of β-catenin stability are not completely known. Here, our recent studies have shown that KCTD1 strongly inhibits TCF/LEF reporte...

Wingless-integrated/β-catenin (Wnt/β-catenin) signaling pathway is an evolutionarily conserved which not only important for regulation of embryogenesis and organ development, but also injury repair, homeostasis tissue remodeling. Dysregulation this either by upregulation or even downregulation highly implicated in various diseases such as; liver diseases, kidney lung fibrosis, heart failure, va...

Wnt/β-catenin signaling is considered to be an essential regulator of adrenocortical oncogenesis. Wnt inhibitory factor-1 (Wif-1), an extracellular regulator of Wnt signaling, is frequently down-regulated by hypermethylation of the promoter CpG. We investigated epigenetic regulation of Wif-1 and its association with adrenocortical (AC) tumor pathogenesis in light of Wnt activation. The AC tumor...

The presence of adherens junctions and the associated protein β-catenin are requirements for development glucose-stimulated insulin secretion (GSIS) in β-cells. Evidence indicates that modulation function response to changes glucose levels can modulate from β-cells but role phosphorylation this process has not been established. We find a Ser552Ala version attenuates indicating functional Ser552...

The glucagon receptor (GCGR) is a member of the class B G protein-coupled receptor family. Activation of GCGR by glucagon leads to increased glucose production by the liver. Thus, glucagon is a key component of glucose homeostasis by counteracting the effect of insulin. In this report, we found that in addition to activation of the classic cAMP/protein kinase A (PKA) pathway, activation of GCGR...

The hypoxia-inducible factor (HIF)-1 and β-catenin protective pathways represent the two most significant cellular responses that are activated in response to acute kidney injury. We previously reported that murine mucin (Muc)1 protects kidney function and morphology in a mouse model of ischemia-reperfusion injury (IRI) by stabilizing HIF-1α, enhancing HIF-1 downstream signaling, and thereby pr...

β-Catenin is a multifunctional protein with critical roles in cell-cell adhesion, Wnt signaling, and the centrosome cycle. Whereas the regulation of β-catenin in cell-cell adhesion and Wnt signaling are well understood, how β-catenin is regulated at the centrosome is not. NIMA-related protein kinase 2 (Nek2), which regulates centrosome disjunction/splitting, binds to and phosphorylates β-cateni...

Thyroid cancer 1 (TC-1, C8ofr4) is widely expressed in vertebrates and associated with many kinds of tumors. Previous studies indicated that TC-1 functions as a positive regulator in the Wnt/β-catenin signaling pathway in non-small cell lung cancer (NSCLC). However, its exact role and regulation mechanism in radiosensitivity of NSCLC are still unclear. The expression level of TC-1 was measured ...

UVB-induced inflammation, in particular the overexpression of cyclooxygenase-2 (COX-2) and prostaglandin (PG) E2, has been implicated in photocarcinogenesis. UVB-induced COX-2 has been associated with β-catenin signaling in keratinocytes. However, a definitive role for COX-2 in the activation of β-catenin signaling as well as its role in UVB-induced skin tumors has not been established. We repo...
