The Molecular Interplay Between p53-Mediated Ferroptosis and Non-Coding RNAs in Cancer.

Area of Science:

• Biochemistry
• Molecular Biology
• Cancer Research

Background:

• Ferroptosis is an iron-dependent cell death characterized by phospholipid peroxidation.
• It is a key mechanism in tumor suppression, immune response, and overcoming anticancer therapy resistance.
• The tumor suppressor p53 is a critical regulator of ferroptosis, with context-dependent roles in promoting or inhibiting this cell death pathway.

Purpose of the Study:

• To review the molecular interplay between p53-mediated ferroptosis and non-coding RNAs (ncRNAs).
• To elucidate how this interplay influences the outcome of ferroptosis in various biological contexts.
• To highlight the significance of this network in cancer therapy and tumor suppression.

Main Methods:

• Literature review of recent studies on p53, ferroptosis, and ncRNAs.
• Analysis of molecular mechanisms governing the p53-ncRNA-ferroptosis axis.
• Synthesis of findings on the regulatory roles of microRNAs (miRNAs) and long non-coding RNAs (lncRNAs).

Main Results:

• p53 modulates ferroptosis susceptibility through transcriptional regulation of target genes.
• ncRNAs, including miRNAs and lncRNAs, are integral components of the p53 regulatory network.
• These ncRNAs can either directly regulate p53 or be regulated by p53, forming a complex feedback loop.
• The intricate network between p53 and ncRNAs dictates the cellular response to ferroptosis.

Conclusions:

• The interplay between p53 and ncRNAs is fundamental to the regulation of ferroptosis.
• Understanding this molecular network is crucial for developing novel therapeutic strategies targeting ferroptosis in cancer.
• This axis offers potential avenues for combating resistance to existing anticancer therapies.
