Insight into Iron, Oxidative Stress and Ferroptosis: Therapy Targets for Approaching Anticancer Strategies

Area of Science:

• Cellular Biology
• Biochemistry
• Oncology

Background:

• Iron is a vital micronutrient crucial for cellular functions.
• Iron's dual role in biology includes promoting essential processes and causing oxidative stress.
• This oxidative stress is linked to both cancer development and cancer cell death pathways.

Purpose of the Study:

• To review the paradoxical role of iron in biological systems.
• To explore the specific correlation between iron and cancer.
• To discuss ferroptosis as a key iron-dependent cell death pathway in cancer.

Main Methods:

• Literature review of molecular machinery controlling iron homeostasis.
• Analysis of iron's role in oxidative stress and cancer.
• Examination of ferroptosis pathways and their distinction from other cell death types.

Main Results:

• Iron overload can lead to oxidative stress, contributing to cancer risk.
• Ferroptosis is an iron-dependent regulated cell death (RCD) pathway.
• Cancer cells exhibit vulnerabilities to ferroptosis due to metabolic alterations and ROS production.

Conclusions:

• Targeting ferroptosis presents a promising therapeutic strategy for cancer suppression.
• Understanding ferroptosis mechanisms can reveal new avenues for treating cancers with limited options.
• Cancer cell-specific vulnerabilities to ferroptosis warrant further investigation for targeted therapies.
