Summary
Caveolin-1 (CAV1) plays a dual role in breast cancer (BC), acting as both an oncogene and tumor suppressor. Understanding CAV1's function is crucial for developing personalized BC therapies and predicting treatment response.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Breast cancer (BC) remains a complex, multifactorial disease despite advances in treatment.
- Omics-based research has improved BC recovery rates, yet challenges persist in effective treatment.
- Caveolin-1 (CAV1) is a key protein in caveolae, emerging as a significant factor in BC.
Purpose of the Study:
- To review the multifaceted biological roles of Caveolin-1 (CAV1) in breast cancer (BC).
- To explore CAV1's contrasting functions as both an oncogene and a tumor suppressor.
- To examine CAV1's influence on BC cell response to chemotherapy, radiation, and oxidative stress.
Main Methods:
- Literature review of existing studies on CAV1 in breast cancer.
- Analysis of CAV1's role in cellular processes, including response to therapy and oxidative stress.
- Evaluation of CAV1's potential as a prognostic indicator in BC.
Main Results:
- CAV1 exhibits dual functions in BC, acting as both an oncogene and a tumor suppressor.
- CAV1 modulates breast cancer cell response to chemotherapy and ionizing radiation therapy.
- CAV1's expression in both epithelium and stroma may serve as a prognostic indicator.
Conclusions:
- CAV1's complex roles necessitate further investigation for therapeutic targeting in BC.
- CAV1's involvement in cellular stress response and treatment modulation offers potential for personalized medicine.
- CAV1 may provide valuable prognostic information for guiding patient treatment strategies and selecting personalized therapies.

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
