Promoting roles of the secreted frizzled-related protein 2 as a Wnt agonist in lung cancer cells

The secreted frizzled-related protein 2 (SFRP2) plays a pivotal role in the Wnt pathway, however, it functions as an agonist or an antagonist is still controversial. We profiled SFRP2 expression in several lung cancer cell lines, and found that A549 and 95-D exhibited the lowest and the highest level of SFRP2, respectively. Then we employed the SFRP2-overexpressing plasmid and siRNA to transfec...

Fritz: a secreted frizzled-related protein that inhibits Wnt activity

Signaling molecules of the Wnt gene family are involved in the regulation of dorso-ventral, segmental and tissue polarity in Xenopus and Drosophila embryos. Members of the frizzled gene family, such as Drosophila frizzled-2 and rat frizzled-1, have been shown encode Wnt binding activity and to engage intracellular signal transduction molecules known to be part of the Wnt signaling pathway. Here...

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...

exogenous secreted frizzled-related protein-4 modulates steroidogenesis of rat ‎granulosa cells through wnt/bcatenin and pi3k/akt signaling pathways‎

background: it has been reported that secreted frizzled-related protein-4 known as an antagonist of wnt signaling pathway plays a role in luteinization process of rodent granulosa cells. the purpose of this study was twofold: 1) to determine whether recombinant human secreted frizzled-related protein-4 (rhsfrp-4) could directly induce terminal differentiation of rat granulosa cells (gcs) and 2)...

Wnt antagonist, secreted frizzled-related protein 4 (sFRP4), increases chemotherapeutic response of glioma stem-like cells.

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-induced cancer cell death, enabling them to survive and initiate tumor recurrence. We examined the effect of secreted frizzled-related protein 4 (sFRP4), a Wnt signaling antagoni...
