The most frequently mutated gene pairs in pancreatic adenocarcinoma (PAAD) are KRAS and TP53, and our goal is to illustrate the multiomics and molecular dynamics landscapes of KRAS/TP53 mutation and also to obtain prospective novel drugs for KRAS- and TP53-mutated PAAD patients. Moreover, we also made an attempt to discover the probable link amid KRAS and TP53 on the basis of the abovementioned multiomics data.
We utilized TCGA & Cancer Cell Line Encyclopedia data for the analysis of KRAS/TP53 mutation in a multiomics manner. In addition to that, we performed molecular dynamics analysis of KRAS and TP53 to produce mechanistic descriptions of particular mutations and carcinogenesis.
We discover that there is a significant difference in the genomics, transcriptomics, methylomics, and molecular dynamics pattern of KRAS and TP53 mutation from the matching wild type in PAAD, and the prognosis of pancreatic cancer is directly linked with a particular mutation of KRAS and protein stability. Screened drugs are potentially effective in PAAD patients.
KRAS and TP53 prognosis of PAAD is directly associated with a specific mutation of KRAS. Irinotecan and vandetanib are prospective drugs for PAAD patients with KRASG12Dmutation and TP53 mutation.
胰腺导管腺癌(PAAD)中最常发生突变的基因对是 KRAS 和 TP53,我们的目标是阐明 KRAS/TP53 突变的多组学和分子动力学图谱,并为 KRAS 和 TP53 突变的 PAAD 患者获得有前景的新型药物。此外,我们还试图根据上述多组学数据发现 KRAS 和 TP53 之间可能存在的联系。
我们使用 TCGA 和癌症细胞系百科全书数据对 KRAS/TP53 突变进行多组学分析。除此之外,我们还对 KRAS 和 TP53 进行了分子动力学分析,以产生特定突变和癌变的机制描述。
我们发现 PAAD 中 KRAS 和 TP53 突变的基因组、转录组、甲基组和分子动力学模式与匹配的野生型有显著差异,胰腺癌的预后与 KRAS 和蛋白质稳定性的特定突变直接相关。筛选出的药物对 PAAD 患者可能有效。
PAAD 的 KRAS 和 TP53 预后与 KRAS 的特定突变直接相关。伊立替康和凡德他尼是 KRASG12D 突变和 TP53 突变的 PAAD 患者的潜在药物。
