Pancreatic adenocarcinoma (PAAD) has become the major cause of cancer-related deaths globally. The m6A (N6-methyladenosine) alteration plays a crucial function in carcinogenesis and tumor progression. The role of genes related to m6A and their expression level in pancreatic cancer is not identified yet. The objective of this research analysis is a demonstration of the m6A RNA methylation regulators based as biomarkers for the PAAD diagnosis.
About 23 extensively reported m6A RNA methylation regulators were identified through the Cancer Genome Atlas (TCGA) database. This identification was based on consensus clustering analysis, protein-protein integration (PPI) analysis, risk prognostic model, Cox-regression analysis, String Spearman analysis, and LASSO Cox-regression.
Herein, we conclude that 23 m6A methylation regulators have a strong link with the clinical and molecular characteristics of PAAD. The three subgroups (1/2) of pancreatic adenocarcinoma were identified using the clustering of 23 m6A regulators. Subgroup cluster 2 had a lower survival rate than the subgroup of cluster 1, and the difference in grades between the two groups was substantial. An assessment was performed using the 23 reported m6A methylation regulators. Eight of these can be used as independent PAAD prognostic markers. The consequences of variable IGF2BP3 expression in PAAD were then investigated further.
The key finding of this study was that the m6A methylation regulator gene has the main role in pancreatic tumors, and it may be used as a biomarker in the prognosis of the PAAD and for therapy purposes.
胰腺癌(PAAD)已成为全球癌症相关死亡的主要原因。m6A(N6-甲基腺苷)改变在致癌和肿瘤进展中起着关键作用。与 m6A 相关的基因及其在胰腺癌中的表达水平的作用尚未确定。本研究分析的目的是展示 m6A RNA 甲基化调节剂作为 PAAD 诊断的生物标志物。
通过癌症基因组图谱(TCGA)数据库确定了约 23 个广泛报道的 m6A RNA 甲基化调节剂。这是基于共识聚类分析、蛋白质-蛋白质整合(PPI)分析、风险预后模型、Cox 回归分析、String Spearman 分析和 LASSO Cox 回归分析确定的。
在此,我们得出结论,23 个 m6A 甲基化调节剂与 PAAD 的临床和分子特征密切相关。使用 23 个 m6A 调节剂的聚类鉴定了胰腺腺癌的三个亚组(1/2)。亚组 2 的生存率低于亚组 1,两组之间的等级差异显著。使用 23 个报告的 m6A 甲基化调节剂进行了评估。其中 8 个可作为独立的 PAAD 预后标志物。随后进一步研究了可变 IGF2BP3 在 PAAD 中的表达的后果。
本研究的主要发现是 m6A 甲基化调节剂基因在胰腺肿瘤中起主要作用,它可能作为 PAAD 预后和治疗目的的生物标志物。
