Secreted antagonists of the Wnt signalling pathway.
The extracellular antagonists of the Wnt signalling pathway can be divided into two broad classes. Both classes of molecule prevent ligand-receptor interactions, but by different mechanisms: members of the first class, which include the sFRP (secreted Frizzled-related protein) family, WIF (Wnt inhibitory factor)-1 and Cerberus, primarily bind to Wnt proteins; the second class comprises certain ...
متن کاملWnt Signalling Pathway Parameters for Mammalian Cells
Wnt/β-catenin signalling regulates cell fate, survival, proliferation and differentiation at many stages of mammalian development and pathology. Mutations of two key proteins in the pathway, APC and β-catenin, have been implicated in a range of cancers, including colorectal cancer. Activation of Wnt signalling has been associated with the stabilization and nuclear accumulation of β-catenin and ...
متن کاملThe role of the Wnt signalling pathway in colorectal tumorigenesis.
Colorectal cancer (CRC) is the second largest cause of cancer-related deaths in Western countries. CRC arises from the colorectal epithelium as a result of the accumulation of genetic alterations in defined oncogenes and tumour suppressor genes. Mutations in the tumour suppressor APC (adenomatous polyposis coli) genes occur early in the development of CRC and lead to the stabilization of the Wn...
متن کاملPrednisolone induces the Wnt signalling pathway in 3T3-L1 adipocytes
Synthetic glucocorticoids are potent anti-inflammatory drugs but show dose-dependent metabolic side effects such as the development of insulin resistance and obesity. The precise mechanisms involved in these glucocorticoid-induced side effects, and especially the participation of adipose tissue in this are not completely understood. We used a combination of transcriptomics, antibody arrays and ...
متن کاملBcr is a negative regulator of the Wnt signalling pathway.
The Wnt signalling pathway can activate transcription of genes such as c-myc through beta-catenin. Here, we describe the protein breakpoint cluster region, Bcr, as a negative regulator of this pathway. Bcr can form a complex with beta-catenin and negatively regulate expression of c-Myc. Knockdown of Bcr by short interfering RNA relieves the block and activates expression of c-Myc. Expression of...
