Epigenetic inactivation of the canonical Wnt antagonist secreted frizzled-related protein 1 in hepatocellular carcinoma cells.
Secreted Frizzled-related protein 1 (sFRP1), as one of most important Wnt antagonists, is frequently silenced by promoter hypermethylation in many types of tumor, including hepatocellular carcinoma (HCC). In this study, we aimed to investigate whether restoration of sFRP1 affected HCC metastatic behavior. sFRP1 mRNA expression and promoter methylation in HCC tissues and cell lines were examined...
متن کاملExpression patterns of Wnt signaling component, secreted frizzled‑related protein 3 in astrocytoma and glioblastoma.
Secreted frizzled-related protein 3 (SFRP3) is a member of the family of soluble proteins, which modulate the Wnt signaling cascade. Novel research has identified aberrant expression of SFRPs in different types of cancer. In the present study the expression intensities and localizations of the SFRP3 protein across different histopathological grades of astrocytic brain tumors were investigated b...
متن کاملEpigenetic inactivation of the secreted frizzled-related protein-5 (SFRP5) gene in human breast cancer is associated with unfavorable prognosis.
Disruption of the Wnt pathway is thought to be crucial in the development of human cancer. Pathway inhibitory members of the secreted frizzled-related protein (SFRP) family were found to be downregulated due to epigenetic inactivation in various malignancies. To date, only SFRP1 has been studied in human breast cancer and we questioned whether other SFRP genes may be implicated in the pathogene...
متن کاملDevelopmental expression patterns of mouse sFRP genes encoding members of the secreted frizzled related protein family
Development of the metanephric kidney is an experimental model system to analyze interactions between mesenchymal and epithelial cells and mesenchymal-epithelial transition. To study the underlying genetic mechanisms we employed organ culture and differential display PCR to identify genes regulated upon induction of mesenchymal cells. One of the genes found encodes the secreted frizzled related...
