b-Catenin is a multifunctional molecule with important roles in intercellular adhesion and signal transduction. We reported previously that b-catenin is mutated in human prostate cancer. In this study, we investigated the role of b-catenin mutations on androgen receptor (AR) signaling. b-Catenin significantly enhanced androgen-stimulated transcriptional activation by the AR. b-Catenin also incr...
Wnt/β-catenin signaling plays a key role in the pathogenesis of colon and other cancers; emerging evidence indicates that oncogenic β-catenin regulates several biological processes essential for cancer initiation and progression. To decipher the role of β-catenin in transformation, we classified β-catenin activity in 85 cancer cell lines in which we performed genome-scale loss-of-function scree...
Wnt signalling and the signal transducer and activator of transcription 3 (STAT3) are oncogenic signalling pathways which are deregulated in colorectal cancer (CRC). Here we investigated the interaction of these two pathways. Firstly, we investigated biochemical interaction by inhibiting STAT3 and β-catenin (through gene knock-down and dominant-negative TCF4 expression) in nine CRC cell lines. ...
β-Catenin is a major transducer of the Wnt signaling pathway, which is aberrantly expressed in colorectal and other cancers. Previously, we showed that β-catenin is downregulated by the 90K glycoprotein via ISGylation-dependent degradation. However, the further mechanisms of β-catenin degradation by 90K-mediated ISGylation pathway were not investigated. This study aimed to identify the β-cateni...
Background: Repairing the burn-injury induced cell death and improving wound healing are critical issues. Objectives: This study was focused on assessment of hydroxychloroquine (HCQ)- recovered burn injury in vivo vitro models. Materials & Methods: In this study, we constructed animal models second-degree burns, showed that heating at 55 Celsius degree for 5 min caused skin cells to switch from...
The cadherin-catenin complex is important for mediating homotypic, calcium-dependent cell-cell interactions in diverse tissue types. Although proteins of this complex have been identified, little is known about their interactions. Using a genetic assay in yeast and an in vitro protein-binding assay, we demonstrate that beta-catenin is the linker protein between E-cadherin and alpha-catenin and ...
background: wnt molecules play a key role in growth, proliferation and development of some embryonic and adult organs as well as hematopoietic stem cells. wnt signaling pathways are aberrantly activated in many tumor types, including solid tumors and hematologic malignancies. objective: to investigate the expression profile of a large number of wnt genes in leukemic cells from iranian patients ...
beta-Catenin and plakoglobin (gamma-catenin) are closely related molecules of the armadillo family of proteins. They are localized at the submembrane plaques of cell-cell adherens junctions where they form independent complexes with classical cadherins and alpha-catenin to establish the link with the actin cytoskeleton. Plakoglobin is also found in a complex with desmosomal cadherins and is inv...
In epithelial cells -catenin plays a critical role as a component of the cell-cell adhesion apparatus and as a coactivator of the TCF/LEF (T-cell transcription factor/lymphoid enhancer binding factor) family of transcription factors. Deregulation of -catenin has been implicated in the malignant transformation of cells of epithelial origin. However, a function for -catenin in hematologic maligna...
Cadherins are transmembrane adhesion molecules that mediate homotypic cell–cell contact. In adherens junctions, the cytoplasmic domain of cadherins is functionally linked to the actin cytoskeleton through a series of proteins known as catenins. E-cadherin binds to β-catenin, which in turn binds to α-catenin to form a ternary complex. α-Catenin also binds to actin, and it was assumed previously ...
