Abstract:
The likelihood of survival for cancer patients has greatly improved due to chemotherapy medicines. However, these antitumor agents might also have unfavorable effects on the cardiovascular system, which could result in sudden or gradual cardiac failure. The production of free radicals that result in oxidative stress appears to be the key mechanism by which chemotherapy-induced cardiotoxicity (CIC) happens. Reports suggest that the Sirtuin-1 (Sirt1)/Nuclear factor E2-associated factor 2 (Nrf2) signaling pathway has been considered an alternative path for counteracting cardiotoxicity by suppressing oxidative stress, inflammation, and apoptosis. This review concludes recent knowledge about CIC with a special focus on the anti-oxidative regulation properties of the Sirt1/Nrf2 pathway.
Insights
Chemotherapy can harm the heart, causing cardiotoxicity through oxidative stress. The Sirtuin-1/Nuclear factor E2-associated factor 2 pathway may protect against this damage by reducing oxidative stress.
Area of Science:
- Cardiovascular Pharmacology
- Oncology
- Molecular Biology
Background:
- Chemotherapy improves cancer survival but can cause cardiotoxicity, leading to heart failure.
- Oxidative stress from free radical production is a primary mechanism of chemotherapy-induced cardiotoxicity (CIC).
Purpose of the Study:
- To review current knowledge on chemotherapy-induced cardiotoxicity.
- To highlight the role of the Sirtuin-1 (Sirt1)/Nuclear factor E2-associated factor 2 (Nrf2) pathway in mitigating CIC.
Main Methods:
- Literature review of studies on chemotherapy-induced cardiotoxicity.
- Analysis of research on the Sirt1/Nrf2 signaling pathway's role in oxidative stress and apoptosis.
Main Results:
- Chemotherapy agents can induce significant cardiovascular damage.
- The Sirt1/Nrf2 pathway demonstrates potential in suppressing oxidative stress, inflammation, and apoptosis associated with CIC.
Conclusions:
- The Sirt1/Nrf2 pathway offers a promising therapeutic target for preventing or treating chemotherapy-induced cardiotoxicity.
- Understanding the anti-oxidative properties of Sirt1/Nrf2 is crucial for managing cardiotoxicity in cancer patients.

Cancer Therapies
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...
