Abstract:
In recent years, ferroptosis has gradually attracted increasing attention because of its important role in tumors. Ferroptosis resistance is an important cause of tumor metastasis, recurrence and drug resistance. Exploring the initiating factors and specific mechanisms of ferroptosis has become a key strategy to block tumor progression and improve drug sensitivity. As the external space in direct contact with tumor cells, the tumor microenvironment has a great impact on the biological function of tumor cells. The relationships between abnormal environmental characteristics (hypoxia, lactic acid accumulation, etc.) in the microenvironment and ferroptosis of tumor cells has not been fully characterized. This review focuses on the characteristics of the tumor microenvironment and summarizes the mechanisms of ferroptosis under different environmental factors, aiming to provide new insights for subsequent targeted therapy. Moreover, considering the presence of anticancer drugs in the microenvironment, we further summarize the mechanisms of ferroptosis to provide new strategies for the sensitization of tumor cells to drugs.
Insights
Ferroptosis, a cell death pathway, is crucial in cancer. Understanding how the tumor microenvironment influences ferroptosis resistance is key to improving cancer treatment and drug sensitivity.
Area of Science:
- Oncology
- Cell Biology
- Cancer Research
Background:
- Ferroptosis is a regulated cell death pathway increasingly recognized for its role in cancer.
- Ferroptosis resistance contributes significantly to tumor metastasis, recurrence, and therapeutic drug resistance.
- Targeting ferroptosis mechanisms is a critical strategy for inhibiting tumor progression and enhancing drug sensitivity.
Purpose of the Study:
- To review the characteristics of the tumor microenvironment (TME).
- To summarize the mechanisms of ferroptosis induction and resistance under various TME factors.
- To explore novel therapeutic strategies for sensitizing tumor cells to anticancer drugs via ferroptosis modulation.
Main Methods:
- Literature review focusing on ferroptosis and the tumor microenvironment.
- Analysis of environmental factors within the TME (e.g., hypoxia, lactic acid) and their impact on ferroptosis.
- Examination of ferroptosis mechanisms in the context of anticancer drug action.
Main Results:
- The TME significantly influences tumor cell biological functions, including ferroptosis.
- Abnormal TME characteristics like hypoxia and lactic acid accumulation are linked to ferroptosis resistance.
- Anticancer drugs can interact with TME components to affect ferroptosis.
Conclusions:
- Understanding TME-mediated ferroptosis is essential for developing effective cancer therapies.
- Targeting ferroptosis pathways within the TME offers promising strategies for overcoming drug resistance and improving patient outcomes.
- Further research into the interplay between the TME, ferroptosis, and drug response is warranted.
