Bone is the most common site of metastases from prostate cancer. The mechanism by which prostate cancer cells metastasize to bone is not fully understood, but interactions between prostate cancer cells and bone cells are thought to initiate the colonization of metastatic cells at that site. Here, we show that cadherin-11 (also known as osteoblast-cadherin) was highly expressed in prostate cance...
Dynamic regulation of endothelial cell adhesion is central to vascular development and maintenance. Furthermore, altered endothelial adhesion is implicated in numerous diseases. Therefore, normal vascular patterning and maintenance require tight regulation of endothelial cell adhesion dynamics. However, the mechanisms that control junctional plasticity are not fully understood. Vascular endothe...
Cadherins are a family of transmembrane glycoproteins that mediate cell-to-cell adhesion. Isoforms, including E- and N-cadherin, have been identified and shown to regulate morphogenesis through homophilic binding. In the ontogeny, the expressions of E- and N-cadherin change spatiotemporally, and the changes in cadherin isoforms, called cadherin switching, impact the mechanical adhesion of cells...
E-cadherin is an important adhesion molecule whose loss is associated with progression and poor prognosis of liver cancer. However, it is unclear whether the loss of E-cadherin is a real culprit or a bystander in liver cancer progression. In addition, the precise role of E-cadherin in maintaining liver homeostasis is also still unknown, especially in vivo. Here we demonstrate that liver-specifi...
To investigate the functions of P-cadherin in vivo, we have mutated the gene encoding this cell adhesion receptor in mice. In contrast to E- and N-cadherin- deficient mice, mice homozygous for the P-cadherin mutation are viable. Although P-cadherin is expressed at high levels in the placenta, P-cadherin-null females are fertile. P-cadherin expression is localized to the myoepithelial cells surr...
background: vhl (von hippel-lindau), runx-3 (runt-related transcription factor 3), e-cadherin (epithelial cadherin), p15 (ink4a, cyclin dependent kinase inhibitor), and p16 (ink4b) genes are essential in hematopoiesis. the aim of this study was to explore the correlation between gene expression and promoter methylation in cd34+ stem cells before and after differentiation to erythroid lineage. m...
There is a growing body of evidence to implicate reversible tyrosine phosphorylation as an important mechanism in the control of the adhesive function of cadherins. We previously demonstrated that the receptor protein tyrosine phosphatase PTP m associates with the cadherin–catenin complex in various tissues and cells and, therefore, may be a component of such a regulatory mechanism (Brady-Kalna...
BACKGROUND Osteoblasts are bone forming cells that play an essential role in osteogenesis. The elucidation of the mechanisms that control osteoblast number is of major interest for the treatment of skeletal disorders characterized by abnormal bone formation. Canonical Wnt signalling plays an important role in the control of osteoblast proliferation, differentiation and survival. Recent studies ...
Cadherins belong to a family of Ca(2+)-dependent homophilic cell-cell adhesion proteins that are important for correct cellular localization and tissue integrity. They play a major role in the development and homeostasis of epithelial architecture. Recently, it has become more and more evident that P-cadherin contributes to the oncogenesis of many tumors. To analyze the role of P-cadherin in or...
