Abstract:
There is increasing evidence that Angiotensin II (AngII), a major regulator of blood pressure and cardiovascular homeostasis, is involved in the regulation of cell proliferation, angiogenesis, inflammation and tissue remodeling, which suggests that this peptide might also play a role in cancer. This review focuses on the expression and function of Angiotensin I-converting enzyme (ACE) and AngII receptors in various aspects of cancer. Recent experimental data suggests that ACE inhibitors and AngII type 1 receptor (AT1R) antagonists have beneficial effects on tumor progression, vascularization and metastasis, and that the AngII type 2 receptor (AT2R) subtype has a potential role in cancer. An overview of the major intracellular signaling pathways associated with AT1R and AT2R activation in cancer cells, as well as in endothelial and inflammatory cells, is presented here.
Insights
Angiotensin II (AngII) plays a role in cancer by influencing cell growth and blood vessel formation. Angiotensin I-converting enzyme (ACE) inhibitors and receptor blockers show potential in cancer treatment.
Area of Science:
- Cardiovascular Science
- Oncology
- Molecular Biology
Background:
- Angiotensin II (AngII) is a key regulator of blood pressure and cardiovascular homeostasis.
- Emerging evidence links AngII to cell proliferation, angiogenesis, inflammation, and tissue remodeling, suggesting a role in cancer.
- The Angiotensin I-converting enzyme (ACE) and its receptors are implicated in various cancer aspects.
Purpose of the Study:
- To review the expression and function of ACE and AngII receptors in cancer.
- To explore the role of AngII type 1 receptor (AT1R) and AngII type 2 receptor (AT2R) in tumor progression.
- To overview intracellular signaling pathways activated by AT1R and AT2R in cancer.
Main Methods:
- Literature review of experimental data on ACE inhibitors and AngII receptor antagonists.
- Analysis of studies investigating AT1R and AT2R roles in tumor vascularization and metastasis.
- Examination of signaling pathways in cancer, endothelial, and inflammatory cells.
Main Results:
- ACE inhibitors and AT1R antagonists demonstrate beneficial effects on tumor progression, vascularization, and metastasis.
- The AT2R subtype shows potential involvement in cancer development.
- Specific intracellular signaling pathways associated with AT1R and AT2R activation are identified.
Conclusions:
- The renin-angiotensin system, particularly AngII and its receptors, is significantly involved in cancer biology.
- Targeting ACE and AngII receptors presents a promising therapeutic strategy for cancer treatment.
- Further research into AT2R's role and detailed signaling mechanisms is warranted for comprehensive cancer therapy development.
