Multifaceted Roles of Guanylate-Binding Proteins in Cancer.

Area of Science:

• Immunology
• Molecular Biology
• Oncology

Background:

• Guanylate-binding proteins (GBPs) are interferon-inducible GTPases vital for innate immunity against intracellular pathogens.
• GBPs recognize pathogen- and danger-associated molecular patterns, mediating lysosomal targeting, inflammation, and apoptosis.
• Their roles extend to cancer, where they can promote or suppress tumor progression depending on the context.

Purpose of the Study:

• To comprehensively review the structural features, immune functions, and cancer-related roles of human GBPs.
• To elucidate the molecular mechanisms underlying GBP involvement in malignancy.
• To explore the prognostic and therapeutic potential of targeting GBPs in cancer treatment.

Main Methods:

• Literature review of existing research on guanylate-binding proteins.
• Analysis of structural, functional, and clinical data related to GBPs in immunity and cancer.
• Synthesis of current insights into GBP mechanisms and therapeutic implications.

Main Results:

• GBPs are key effectors in cell-autonomous immunity against diverse pathogens.
• GBPs exhibit context-dependent functions in cancer, influencing immune signaling, apoptosis, and therapy resistance.
• Specific GBP roles vary across different tumor types, affecting malignancy or suppression.

Conclusions:

• Understanding the complex roles of GBPs in cancer is critical for developing novel therapeutic strategies.
• Targeting GBP regulation may offer new avenues for cancer treatment by modulating anti-tumor immunity or overcoming resistance.
• Further research into GBP mechanisms can refine their prognostic value and clinical applications.
