GPCRs as targets for flavonoids in cancer cells: new options for intervention

Area of Science:

• Oncology
• Pharmacology
• Molecular Biology

Background:

• Receptor tyrosine kinases were historically considered primary drivers of cell proliferation.
• Emerging evidence highlights the role of G protein-coupled receptors (GPCRs) in cancer signaling pathways.
• GPCRs represent significant therapeutic targets for various human cancers.

Purpose of the Study:

• To review the current understanding of GPCRs in the anticancer actions of flavonoids.
• To elucidate the mechanisms by which flavonoids interact with GPCRs to inhibit cancer hallmarks.
• To highlight the potential of flavonoid-GPCR interactions as a novel cancer therapy.

Main Methods:

• Literature review of existing studies on flavonoids, GPCRs, and cancer.
• Analysis of data on flavonoid modulation of GPCR expression and activity.
• Compilation of evidence on downstream signaling events affected by flavonoid-GPCR interactions.

Main Results:

• Flavonoids exhibit diverse anticancer effects, including inhibition of growth, proliferation, migration, and invasion.
• Flavonoids can modulate GPCR expression levels.
• Flavonoids suppress the action of endogenous ligands and downstream tumor-promoting events mediated by GPCRs.

Conclusions:

• GPCRs play a crucial role in the anticancer activities of flavonoids.
• Targeting specific GPCRs with flavonoids offers a promising therapeutic approach for human malignancies.
• Further research into flavonoid-GPCR interactions can lead to novel cancer treatment strategies.
