Triple-negative breast cancer (TNBC) is characterized by aggressive behavior, high metastatic potential, and frequent relapses, presenting significant treatment challenges. Ferroptosis, a unique form of programmed cell death marked iron-dependent lipid peroxidation, has emerged as crucial factor in biology. Recent studies indicate that TNBC cells possess distinct metabolic profile linked to iron glutathione, which may render them more susceptible ferroptosis than other subtypes. Moreover, plays role the interactions between immune tumor cells, suggesting its potential modulate microenvironment influence response against TNBC.Evidence reveals not only affects viability but also alters promoting release damage-associated molecular patterns (DAMPs), can recruit site. Specific ferroptosis-related genes biomarkers, such ACSL4 GPX4, demonstrate altered expression tissues, offering promising avenues for diagnostic prognostic applications. Furthermore, preclinical models, induction been shown enhance efficacy existing therapies, indicating synergistic effect could be harnessed therapeutic benefit. The compelling link underscores novel target. Future research should focus on developing strategies exploit conjunction with traditional including identification natural compounds efficacious inducers personalized regimens. This review elucidates multifaceted implications TNBC, providing valuable insights improving both diagnosis this formidable subtype.

Abstract Ferroptosis is a form of cell death that triggered by the presence ferrous ions and characterized lipid peroxidation induced these ions. The mechanism exhibits distinct morphological characteristics compared to apoptosis, autophagy, necrosis. A notable aspect ferroptosis its ability inhibit uncontrolled tumor replication immortalization, especially in malignant, drug-resistant, metastatic tumors. Additionally, immunotherapy, novel therapeutic approach for tumors, has been found have reciprocal regulatory relationship with context anti-tumor therapy. comprehensive analysis immunotherapy therapy presented this paper, highlighting potential mutual adjuvant effects.

Breast cancer is the most commonly diagnosed worldwide. Metal metabolism pivotal for regulating cell fate and drug sensitivity in breast cancer. Iron copper are essential metal ions critical maintaining cellular function. The accumulation of iron triggers distinct death pathways, known as ferroptosis cuproptosis, respectively. Ferroptosis characterized by iron-dependent lipid peroxidation, while cuproptosis involves copper-induced oxidative stress. They increasingly recognized promising targets development anticancer drugs. Recently, compelling evidence demonstrated that interplay between plays a crucial role progression.
