Therapeutic targeting of FZD receptor proteins with biologics in cancer

Area of Science:

• Oncology
• Molecular Biology
• Drug Discovery

Background:

• Wnt signaling is implicated in cancer initiation, progression, and treatment resistance.
• Current Wnt pathway inhibitors lack selectivity, causing side effects in healthy tissues.
• Targeting individual Frizzled (FZD) receptors offers a promising strategy for selective inhibition.

Purpose of the Study:

• To review the physiological and pathological roles of the ten Frizzled (FZD) receptors.
• To summarize diverse selective biologics developed for FZD receptor targeting.
• To assess the potential of these biologics as safe and efficient anti-Wnt cancer therapies.

Main Methods:

• Literature review of Wnt signaling in cancer.
• Analysis of the roles of ten Frizzled (FZD) receptors.
• Survey of biologics targeting FZD receptors, including antibodies, designer proteins, peptides, nanobodies, and aptamers.

Main Results:

• Each of the ten FZD receptors has distinct physiological and pathological roles.
• Various selective biologics targeting specific FZD receptors have been developed.
• These biologics demonstrate potential for selective cancer treatment.

Conclusions:

• Targeting individual FZD receptors is a viable strategy for developing selective Wnt pathway inhibitors.
• Biologics like antibodies, peptides, and nanobodies show promise for safe and effective cancer therapy.
• Further research into these selective agents could lead to novel anti-cancer treatments.
