[A Review of Epigenetic Modifications Regulate MicroRNA Expression in Lung Cancer]

Area of Science:

• Molecular Biology
• Genetics
• Oncology

Background:

• Lung cancer remains a leading cause of cancer mortality globally.
• While molecular pathways are being uncovered, the precise mechanisms of lung cancer remain unclear.
• MicroRNAs (miRNAs), small non-coding RNAs, regulate vital cellular processes in normal lung development.

Purpose of the Study:

• To explore the role of microRNAs (miRNAs) in lung cancer occurrence, development, and metastasis.
• To investigate the regulatory relationship between miRNAs and the epigenome in lung cancer.
• To assess the potential of miRNA-based strategies for lung cancer diagnosis, therapy, and prognosis.

Main Methods:

• Review of current literature on miRNA function and epigenetic regulation in lung cancer.
• Analysis of miRNA aberrant expression in lung tumor development.
• Examination of the interplay between miRNAs and epigenetic modifications like DNA methylation and histone modification.

Main Results:

• Aberrant miRNA expression is implicated in the initiation, progression, invasion, and metastasis of lung tumors.
• miRNAs regulate epigenetic factors, and conversely, are epigenetically regulated.
• This intricate relationship highlights miRNAs as potential biomarkers for lung cancer.

Conclusions:

• The interplay between miRNAs and the epigenome is critical in lung cancer pathogenesis.
• Targeting miRNAs presents a promising avenue for future lung cancer diagnostics, therapeutics, and prognostics.
• Further research into the miRNA-epigenome axis is essential for advancing lung cancer management.
