The Role of Secreted Frizzled-related Protein-4 (sFRP4) in the Epigenetics, Metabolism and Chemo-sensitisation of Cancer Stem Cells
MetadataShow full item record
This study investigated molecular signals involved in sustaining CSCs and ways to target their activity using sFRP4 alone or in combination with chemotherapeutic drugs, possible involvement of methylation-mediated silencing of the sFRP gene family, and metabolic reprogramming by relocating metabolic flux to glycolysis or oxidative phosphorylation. sFRPs have an ability to sensitize tumour cells to chemotherapeutic drugs, thereby enhancing cell death. Altogether, sFRP4 treatment compromises the cell proliferation, and critically affects the cell survival mechanisms of CSCs.

Wnt antagonist, secreted frizzled-related protein 4 (sFRP4), increases chemotherapeutic response of glioma stem-like cellsWarrier, S.; Balu, S.; Kumar, Alan Prem; Michael, M.; Dharmarajan, Arunasalam (2014)Malignant gliomas have a highly tumorigenic subpopulation, termed cancer stem cells (CSCs), that drives tumor formation and proliferation. CSCs possess inherent resistance mechanisms against radiation- and chemotherapy- ...
SFRP-4 abrogates Wnt-3a-induced ß-catenin and Akt/PKB signalling and reverses a Wnt-3a-imposed inhibition of in vitro mammary differentiationConstantinou, T.; Baumann, F.; Lacher, M.; Saurer, S.; Friis, R.; Dharmarajan, Arunasalam (2008)Background: Conserved Wnt ligands are critical for signalling during development; however, various factors modulate their activity. Among these factors are the Secreted Frizzled-Related Proteins (SFRP). We previously ...
The Wnt regulator SFRP4 inhibits mesothelioma cell proliferation, migration, and antagonizes Wnt3a via its netrin-like domainPerumal, Vanathi; Dharmarajan, Arunasalam; Fox, Simon (2017)Secreted frizzled related proteins (SFRPs) are a family of Wnt regulators which are frequently downregulated in cancers. In malignant mesothelioma (MM), downregulation of SFRP4 has been reported as a mechanism which ...
