Family G-protein coupled receptor Fz/Smo family
Function
Receptor for Wnt proteins. Most frizzled receptors are coupled to the beta-catenin canonical signaling pathway, which leads to the activation of disheveled proteins, inhibition of GSK-3 kinase, nuclear accumulation of beta-catenin and activation of Wnt target genes. A second signaling pathway involving PKC and calcium fluxes has been seen for some family members, but it is not yet clear if it represents a distinct pathway or if it can be integrated in the canonical pathway, as PKC seems to be required for Wnt-mediated inactivation of GSK-3 kinase. Both pathways seem to involve interactions with G-proteins. Activation by WNT8 induces expression of beta-catenin target genes. Following ligand activation, binds to CCDC88C/DAPLE which displaces DVL1 from FZD7 and leads to inhibition of canonical Wnt signaling, activation of G-proteins by CCDC88C and triggering of non-canonical Wnt responses. May be involved in transduction and intercellular transmission of polarity information during tissue morphogenesis and/or in differentiated tissues.

Response regulation FZD7 was a direct target of miR-1-3p, which inhibited the expression of FZD7 by binding to the 3'-untranslated region (3'UTR) site of FZD7. In ovarian cancer tissues, overexpression of FZD7 reduced the sensitivity of platinum-resistant ovarian cancer cells to ferroptosis by up-regulating GPX4 expression.

In Vivo Model
To develop platinum resistant OC cells in vivo, female (6-8 weeks old) athymic nude mice (Foxn1nu, Envigo) were injected subcutaneously (s.c.) with 2 million SKOV3 or OVCAR3 cells, or intraperitoneally (i.p.) with 2 million OVCAR5 cells to induce tumors.

Response regulation Overexpression of FZD7 activated the oncogenic factor Tp63, driving upregulation of glutathione metabolism pathways, including glutathione peroxidase 4 (GPX4), which protected cells from chemotherapy-induced oxidative stress. FZD7 platinum-tolerant ovarian cancer cells were more sensitive and underwent ferroptosis after treatment with GPX4 inhibitors.
