During the past decade, the average 5-year survival rate of patients with Lung adenocarcinoma (LUAD) has remained < 20%, although the targeted therapies and novel immunotherapy approaches have held promise. Epigenetic modifications could provide prognostic value as molecular biomarkers, and we aimed to identify the independent risk of m6A-related lncRNAs to establish a risk model for the clinical prediction of prognoses in women with LUAD. In this study, we first assessed 31 N6-methyladenosine (m6A)-related lncRNAs associated with overall survival. Moreover, we evaluated the expression of the oncogenic driver and the tumor immune microenvironment (TIME) in two female LUAD subtypes (clusters 1 and 2) using consensus clustering. We also found 16 m6A-related lncRNAs as the independent prognostic indicator of women with LUAD and established a risk model developed from these lncRNAs. We comprehensively investigated the correlation between the TIME and m6A-related lncRNA and found that m6A-related lncRNA may significantly affect the immune cell infiltration level in LUAD. In conclusion, our study provides evidence on the prognostic prediction in women with LUAD and may help elucidate the processes and mechanisms of m6A-regulated lncRNAs.
在过去的十年中,尽管靶向治疗和新型免疫疗法有一定的前景,但肺腺癌(LUAD)患者的平均 5 年生存率仍<20%。表观遗传修饰可以作为分子生物标志物提供预后价值,我们旨在确定 m6A 相关 lncRNA 的独立风险,以建立 LUAD 女性临床预后预测的风险模型。在这项研究中,我们首先评估了 31 个与总生存期相关的 N6-甲基腺苷(m6A)相关 lncRNA。此外,我们使用共识聚类评估了两个女性 LUAD 亚型(簇 1 和 2)中致癌驱动因子和肿瘤免疫微环境(TIME)的表达。我们还发现了 16 个 m6A 相关 lncRNA 作为 LUAD 女性的独立预后指标,并从这些 lncRNA 建立了一个风险模型。我们全面研究了 TIME 和 m6A 相关 lncRNA 之间的相关性,发现 m6A 相关 lncRNA 可能显著影响 LUAD 中免疫细胞浸润水平。总之,我们的研究为 LUAD 女性的预后预测提供了证据,并可能有助于阐明 m6A 调节的 lncRNA 的过程和机制。
