Introduction:
Breast cancer is the most common form of cancer diagnosed worldwide and the leading cause of death in women globally, according to Globocan 2020. Hence, investigating novel pathways implicated in cancer progression and metastasis could lead to the development of targeted therapies and new treatment strategies in breast cancer. Recent studies reported an interplay between the receptor for advanced glycation end products (RAGE) and its ligands, S100 protein group, advanced glycation end products (AGEs) and high-mobility group box 1 protein (HMGB1) and breast cancer growth and metastasis.
Materials And Methods:
We used articles available in the NCBI website database PubMed to write this scoping review. The search words used were 'RAGE receptor' AND/OR 'breast cancer, RAGE ligands, glycation end products'. A total of 90 articles were included. We conducted a meta-analysis to assess the relationship between the RAGE rs1800624 polymorphism and breast cancer risk using fixed-effect or random-effect models to calculate odds ratios (ORs) and their corresponding 95% confidence intervals (95% CIs).
Results:
RAGE upon activation by its ligands enhances downstream signaling pathways, contributing to breast cancer cells migration, growth, angiogenesis, metastasis, and drug resistance. In addition, studies have shown that RAGE and its ligands influence the way breast cancer cells interact with immune cells present in the tumor microenvironment (macrophages, fibroblasts), thus regulating it to promote tumor growth and metastasis.
Conclusion:
Breast cancers with a high expression of RAGE are associated with poor prognosis. Targeting RAGE and its ligands impairs cell invasion and metastasis, showing promising potential for further research as potential prognostic biomarkers or targeted onco-therapeutics.
Insights
The receptor for advanced glycation end products (RAGE) and its ligands play a key role in breast cancer progression and metastasis. Targeting RAGE offers potential for new breast cancer therapies and prognostic biomarkers.
Area of Science:
- Oncology
- Molecular Biology
Background:
- Breast cancer is a leading cause of cancer death globally.
- The receptor for advanced glycation end products (RAGE) and its ligands are increasingly implicated in cancer progression.
Purpose of the Study:
- To review the role of RAGE and its ligands in breast cancer growth and metastasis.
- To assess the relationship between RAGE polymorphism and breast cancer risk.
Main Methods:
- Scoping review of 90 articles from PubMed.
- Meta-analysis of the RAGE rs1800624 polymorphism and breast cancer risk.
Main Results:
- RAGE activation promotes breast cancer cell migration, growth, angiogenesis, metastasis, and drug resistance.
- RAGE and its ligands modulate the tumor microenvironment to enhance tumor growth.
- High RAGE expression in breast cancer correlates with poor prognosis.
Conclusions:
- Targeting RAGE and its ligands can impair breast cancer invasion and metastasis.
- RAGE and its ligands show potential as prognostic biomarkers and therapeutic targets for breast cancer.
