M6A-Mediated Methylation Patterns and Their Association With Obstructive Sleep Apnea in Lung Adenocarcinoma.

ABSTRACT:

Background

Epigenetic regulation significantly affects immune responses in lung adenocarcinoma (LUAD). However, the role of RNA N6-methyladenosine (m6A) modification, especially in obstructive sleep apnea-hypopnea syndrome (OSAHS) within LUAD, is not well understood.

Methods

This study examined m6A modification patterns in 973 LUAD patients using 23 regulatory genes. Unsupervised clustering categorized patients by m6A profiles, quantified by an m6A score. Associations with clinical outcomes, including survival, immune infiltration, tumor microenvironment, OSAHS incidence, and drug sensitivity, were analyzed.

Results

m6A regulator mutations were linked to LUAD, revealing two distinct modification patterns and three gene clusters, all tied to immune phenotypes and clini
