G protein-coupled receptors (GPCRs) are key membrane proteins involved in cancer. Understanding their complex signaling pathways, particularly biased signaling, is crucial for developing targeted cancer therapies.
Area of Science:
- Molecular Biology
- Cellular Biology
- Pharmacology
Background:
- G protein-coupled receptors (GPCRs) are a large class of membrane proteins mediating cellular responses.
- GPCRs regulate vital physiological functions and are implicated in various diseases, including cancer.
- Abnormal GPCR signaling in tumors promotes carcinogenesis by influencing immune evasion, proliferation, and therapeutic resistance.
Purpose of the Study:
- To review the complexity of GPCRs and their role in cancer signaling.
- To focus on differential pathway activation by G proteins and β-arrestin.
- To explore targeted modulation of GPCR signaling for cancer treatment.
Main Methods:
- Literature review of GPCR structure-function relationships.
- Analysis of GPCR-biased signaling mechanisms.
- Examination of emerging technologies for GPCR targeting.
Main Results:
- GPCRs' seven-transmembrane structure facilitates diverse signaling networks.
- Pathway-specific GPCR activation and biased ligand discovery are critical research areas.
- Targeted modulation of GPCR signaling pathways shows therapeutic potential in cancer.
Conclusions:
- Understanding GPCR-biased signaling offers insights into cancer biology.
- Emerging technologies like aptamers, PROTACs, and nanobodies enable precise GPCR targeting.
- Modulating GPCR signaling pathways may lead to more effective cancer therapies.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
