Decoding the molecular symphony: interactions between the m⁶A and p53 signaling pathways in cancer

Area of Science:

• Oncology
• Molecular Biology
• Epigenetics

Background:

• The p53 tumor suppressor gene is crucial for anti-cancer functions.
• Dysregulation of p53 signaling, often through missense mutations, contributes to cancer development.
• The N6-methyladenosine (m6A) epitranscriptomic network, a key post-transcriptional modification, influences numerous cellular processes.

Purpose of the Study:

• To review the intricate relationship between the p53 signaling pathway and the m6A epitranscriptome.
• To elucidate how this interplay affects tumorigenesis and cancer hallmarks.
• To identify potential therapeutic implications arising from this interaction.

Main Methods:

• Literature review synthesizing recent findings on p53 and m6A interactions.
• Analysis of studies investigating the impact of wild-type and mutant p53 on m6A regulators (readers, writers, erasers).
• Examination of how these interactions influence cancer hallmarks and cellular functions.

Main Results:

• Significant interactions between p53 (both wild-type and mutant forms) and the m6A network have been identified across various cancer types.
• Cross-talk between p53 and m6A regulators impacts gene transcription, oncogenic signaling, and cellular processes.
• This interaction influences key cancer hallmarks, contributing to tumor formation and progression.

Conclusions:

• The interplay between p53 and the m6A epitranscriptome represents a critical, previously underappreciated, mechanism in cancer.
• Targeting this interaction holds promise for novel cancer therapeutic strategies.
• Further research into this molecular axis is warranted for clinical translation.
