Non-coding RNA methylation modifications in ovarian cancer.

Area of Science:

• Molecular Biology
• Oncology
• Epigenetics

Background:

• Ovarian cancer (OC) is a heterogeneous gynecological malignancy with high mortality.
• Non-coding RNAs (ncRNAs) regulate gene expression and protein function.
• RNA methylation (m6A, m1A, m5C, m7G) is a crucial post-transcriptional modification involved in various biological processes and cancer development.

Purpose of the Study:

• To review common RNA methylation modifications and their associated enzymes.
• To summarize methylated ncRNAs implicated in ovarian cancer regulation.
• To explore the mechanisms of ncRNA methylation in OC occurrence, proliferation, immune response, and drug resistance.

Main Methods:

• Literature review of scholarly inquiries on RNA methylation and ovarian cancer.
• Summary of four common RNA methylation types and their enzymes.
• Analysis of current reports on ncRNA methylation's role in OC.

Main Results:

• Methylation alterations in ncRNAs are implicated in the etiology of ovarian cancer.
• ncRNA methylation influences OC occurrence, proliferation, immune response, and drug resistance.
• Specific methylation-related long non-coding RNAs (lncRNAs) show potential for further study.

Conclusions:

• RNA methylation, particularly in ncRNAs, plays a significant role in ovarian cancer pathogenesis.
• Understanding ncRNA methylation mechanisms offers insights into OC development and treatment.
• Methylation-related lncRNAs represent promising targets for future research and therapeutic strategies in ovarian cancer.
