An Overview of Current Detection Methods for RNA Methylation

Area of Science:

• Epitranscriptomics
• Molecular Biology
• Gene Regulation

Background:

• Epitranscriptomic mechanisms, particularly RNA methylation, are crucial post-transcriptional regulators in eukaryotic cells.
• RNA methylation marks like N6-methyladenosine (m6A) dynamically influence RNA fate, affecting translation, stability, and processing.
• Dysregulation of RNA methylation is implicated in diseases such as cancer and in developmental processes.

Purpose of the Study:
