In canonical Wnt signaling, the protein levels of the key signaling mediator β-catenin are under tight regulation by the multimeric destruction complex that mediates proteasomal degradation of β-catenin. In colorectal cancer, destruction complex activity is often compromised due to mutations in the multifunctional scaffolding protein Adenomatous Polyposis Coli (APC), leading to a stabilization ...
Kindlin 2, as a focal adhesion protein, controls integrin activation. However, the association of Kindlin 2 with cancer-related signalling pathways is unknown. Here we identified a new direct interaction between Kindlin 2 and the active β-catenin. Importantly, Kindlin 2 forms a tripartite complex with β-catenin and TCF4. Mechanistically, Kindlin 2 selectively strengthens the occupancy of β-cate...
BACKGROUND Axin1 and its homolog Axin2 are scaffold proteins essential for regulating Wnt signaling. Axin-dependent regulation of Wnt is important for various developmental processes and human diseases. However, the involvement of Axin1 and Axin2 in host defense and inflammation remains to be determined. METHODS/PRINCIPAL FINDINGS Here, we report that Axin1, but not Axin2, plays an essential ...
Background: SALL2 is a developmental transcription factor involved in the regulation of cell proliferation, migration, and survival. Massive data analyses cancer versus normal tissues indicate that mRNA significantly decreased colorectal (CRC), type characterized by hyperactivation Wnt pathway. Interestingly, our previous ChIP-seq suggested regulates genes associated with pathway, including neg...
Purpose The scaffold protein Axin2 is an antagonist and universal target of the Wnt/β-catenin pathway. Disruption of Axin2 may lead to developmental eye defects; however, this has not been examined. The purpose of this study was to investigate the role of Axin2 during ocular and extraocular development in mouse. Methods Animals heterozygous and homozygous for a Axin2lacZ knock-in allele were ...
Familial adenomatous polyposis has been linked to germline mutations in the APC tumor suppressor gene. However, a number of patients with familial adenomatous polyposis (with either classical or attenuated phenotype) have no APC mutation. Recently, germline mutations in the Wnt pathway component gene AXIN2 have been associated with tooth agenesis-colorectal cancer syndrome. Moreover, biallelic ...
SOX7 co-regulates Wnt/β-catenin signaling with Axin-2: both expressed at low levels in breast cancer
SOX7 as a tumor suppressor belongs to the SOX F gene subfamily and is associated with a variety of human cancers, including breast cancer, but the mechanisms involved are largely unclear. In the current study, we investigated the interactions between SOX7 and AXIN2 in their co-regulation on the Wnt/β-catenin signal pathway, using clinical specimens and microarray gene expression data from the G...
BACKGROUND Findings of recent studies have demonstrated a rapid increase of the incidence of papillary thyroid carcinoma (PTC), which accounts for nearly 80% of thyroid cancers. OBJECTIVES The aim of this study was to explore the association between AXIN2 gene polymorphism and papillary thyroid carcinoma (PTC). PATIENTS AND METHODS 106 blood samples (56 PTC patients and 50 healthy controls)...
Bone formation and skeletal repair are dynamic processes involving a fine-tuned balance between osteoblast proliferation and differentiation orchestrated by multiple signaling pathways. Canonical Wnt (cWnt) signaling is known to playing a key role in these processes. In the current study, using a transgenic mouse model with targeted disruption of axin2, a negative regulator of cWnt signaling, w...
