Insights
Drug-induced cardiotoxicity can cause severe heart problems. This review details cardiomyocyte death mechanisms and proteins, offering targets for preventing and treating drug-induced heart damage.
Area of Science:
- Cardiology
- Toxicology
- Molecular Biology
Background:
- Homeostatic regulation of cardiomyocytes is vital for cardiac function.
- Drug-induced cardiotoxicity leads to serious cardiac diseases like arrhythmia and myocardial infarction.
- Certain clinical drugs, including anti-cancer and anti-diabetic agents, can cause cardiotoxicity.
Purpose of the Study:
- To review cardiomyocyte death forms and mechanisms in drug-induced cardiotoxicity.
- To identify key proteins involved in cardiomyocyte death signaling pathways.
- To provide a theoretical basis for preventing and treating drug-induced cardiotoxicity.
Main Methods:
- Literature review of studies on drug-induced cardiotoxicity.
- Analysis of cardiomyocyte death pathways: apoptosis, autophagy, necrosis, necroptosis, pyroptosis, and ferroptosis.
- Evaluation of key proteins in cardiomyocyte death signaling.
Main Results:
- Drug-induced cardiotoxicity manifests through diverse cardiomyocyte death mechanisms.
- Specific proteins are critical in mediating these death pathways.
- Understanding these mechanisms and proteins is essential for clinical management.
Conclusions:
- Drug-induced cardiotoxicity is a significant clinical challenge.
- Targeting cardiomyocyte death pathways and proteins offers potential therapeutic strategies.
- This review provides a foundation for developing interventions against drug-induced heart damage.
Abstract:
Homeostatic regulation of cardiomyocytes plays a crucial role in maintaining the normal physiological activity of cardiac tissue. Severe cardiotoxicity results in cardiac diseases including but not limited to arrhythmia, myocardial infarction and myocardial hypertrophy. Drug-induced cardiotoxicity limits or forbids further use of the implicated drugs. Such drugs that are currently available in the clinic include anti-tumor drugs (doxorubicin, cisplatin, trastuzumab, etc.), antidiabetic drugs (rosiglitazone and pioglitazone), and an antiviral drug (zidovudine). This review focused on cardiomyocyte death forms and related mechanisms underlying clinical drug-induced cardiotoxicity, including apoptosis, autophagy, necrosis, necroptosis, pryoptosis, and ferroptosis. The key proteins involved in cardiomyocyte death signaling were discussed and evaluated, aiming to provide a theoretical basis and target for the prevention and treatment of drug-induced cardiotoxicity in the clinical practice.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
