Emerging function of N6-methyladenosine in cancer

Area of Science:

• Epigenetics and RNA Biology
• Molecular Oncology

Background:

• N6-methyladenosine (m6A) is a prevalent RNA modification involved in fundamental biological processes.
• The precise biological roles of m6A remained largely elusive until recent advancements.
• m6A modification is dynamically regulated by 'writers', 'erasers', and 'readers'.

Purpose of the Study:

• To review the current understanding of m6A modification in biological processes and disease.
• To discuss the role of m6A dysregulation in the development of various cancers.
• To explore the dual oncogenic and tumor-suppressive functions of m6A metabolic factors.

Main Methods:

• Review of existing literature on m6A modification.
• Analysis of next-generation sequencing data for m6A mapping.
• Integration of studies on m6A regulators (writers, erasers, readers) and their roles in cancer.

Main Results:

• m6A modification patterns are conserved across mammalian transcriptomes.
• Aberrant m6A regulation is significantly associated with multiple cancer types.
• Factors governing m6A metabolism exhibit context-dependent oncogenic or tumor-suppressor activities.

Conclusions:

• m6A RNA modification plays a critical role in cellular functions, development, and disease.
• The dysregulation of m6A pathways is a hallmark of cancer progression.
• Targeting m6A metabolism presents a potential therapeutic strategy for cancer treatment.
