Comprehensive analysis reveals the prognostic and immunogenic characteristics of DNA methylation regulators in lung adenocarcinoma.

ABSTRACT: DNA methylation regulators (DMRs) play a key role in DNA methylation, thus mediating tumor occurrence, metastasis, and immunomodulation. However, the effects of DMRs on clinical outcomes and immunotherapy response remain unexplored in lung adenocarcinoma (LUAD). In this study, eight LUAD cohorts and one immunotherapeutic cohort of lung cancer were utilized. We constructed a DNA methylation regulators-related signature (DMRRS) using univariate and multivariate COX regression analysis. The DMRRS-defined low-risk group was preferentially associated with favorable prognosis, tumor-inhibiting microenvironment, more sensitivity to several targeted therapy drugs, and better immune response. Afterward, the prognostic value and predictive potential in immunotherapy response were validated. Collecti
