A novel m7G methylation-related signature associated with chromosome homeostasis in patients with lung adenocarcinoma.

ABSTRACT: Lung adenocarcinoma (LUAD) is a malignant tumor of the respiratory system with poor prognosis. Recent studies have revealed that N7-methylguanosine (m7G) methylation is a widespread modification occurring in RNA. But the expression of m7G methylation-related genes in LUAD and their correlations with prognosis are still unclear. In this study, we found 12 m7G methylation-related regulators with differential expression between LUAD and normal lung tissues. According to differentially expressed genes (DEGs), all LUAD cases were separated into two subtypes. The prognostic value of each m7G methylation-related gene for survival was evaluated to construct a multigene signature using The Cancer Genome Atlas (TCGA) cohort. Finally, an m7G methylation-related prognostic signature based on three gen
