RNA m⁶A modification and its function in diseases.

Area of Science:

• Molecular Biology
• Epigenetics
• RNA Biology

Background:

• N6-methyladenosine (m6A) is the most prevalent epitranscriptomic mark, influencing RNA metabolism.
• m6A levels are dynamically regulated by methyltransferases (writers) and demethylases (erasers).
• m6A "readers" interpret the modification, mediating downstream cellular effects.

Purpose of the Study:

• To review recent advancements in understanding m6A "writers", "erasers", and "readers".
• To highlight the functional significance of m6A in various cellular contexts and diseases.
• To underscore the importance of m6A research in oncology.

Main Methods:

• Literature review of recent studies on m6A modulators.
• Analysis of m6A's role in vitro cell lines and physiological conditions.
• Examination of m6A's involvement in cancer development and progression.

Main Results:

• Significant progress has been made in identifying and characterizing m6A "writers", "erasers", and "readers".
• m6A modification plays crucial roles in diverse cellular processes, including proliferation, differentiation, and stress response.
• Emerging evidence links dysregulated m6A to various human cancers, suggesting its potential as a therapeutic target.

Conclusions:

• m6A is a critical regulator of gene expression with profound implications in normal physiology and disease.
• Further research is needed to elucidate the complex regulatory networks and mechanisms of m6A.
• Investigating m6A's role in human diseases, particularly cancer, holds promise for novel diagnostic and therapeutic strategies.
