This study was conducted to explore the potential genes and proteins associated with esophagus benign hyperplasia induced by esophageal stents. Five patients with esophageal cancer subjected to esophageal stent placement were enrolled in this study. Long non-coding RNA (lncRNA) sequencing and tandem mass tag quantitative proteomics analysis were performed by using the collected hyperplastic samples and adjacent non-hyperplastic tissues. Differentially expressed (DE) RNAs and proteins were analyzed, followed by functional enrichment analysis, protein-protein interaction (PPI) network analysis, and competitive endogenous RNA (ceRNA) network construction. Venn analysis was performed to extract the overlaps between DE mRNAs and DE proteins and the expression correlations between DE mRNA and proteins were analyzed. Results showed that total 642 DE RNAs (457 mRNA and 185 lncRNAs) and 256 DE proteins were detected. DE mRNAs (such as , , and ) were enriched in oxidation-reduction process-associated functions. PPI network was comprised of 175 nodes and 425 edges. VEGFA was a significant node with the highest degree. LncRNA-mRNA network with three subnetworks (C1, C2, C3) was constructed for lncRNAs with more than 15 gene targets. RP11-58O9.2 was a significant lncRNA with the most target genes and RP11-667F14.1 regulated more than 20 targets. was a common target of the two lncRNAs. Function analysis showed that DE lncRNAs were involved in the HTLV-I infection (RP11-58O9.2 and RP11-667F14.1) and IL-17 signaling pathways (RP11-5O24.1 and RP11-58O9.2). Total 11 DE mRNAs were overlapped with DE proteins, among which MAOB and SDR16C5 showed positive correlations between mRNA and protein expression. Function analysis showed that was enriched in oxidation-reduction process and its protein was closely related with response to lipopolysaccharide. , , , , RP11-58O9.2, RP11-667F14.1, and RP11-288A5.2 may be served as genetic targets for preventing stent restenosis in esophageal cancer.
本研究旨在探索与食管支架诱导的食管良性增生相关的潜在基因和蛋白质。本研究纳入了5例接受食管支架置入的食管癌患者。利用收集的增生性样本和相邻的非增生性组织进行长链非编码RNA(lncRNA)测序和串联质谱标签定量蛋白质组学分析。分析差异表达(DE)的RNA和蛋白质,随后进行功能富集分析、蛋白质-蛋白质相互作用(PPI)网络分析和竞争性内源RNA(ceRNA)网络构建。进行Venn分析以提取DE mRNA和DE蛋白质之间的重叠部分,并分析DE mRNA与蛋白质之间的表达相关性。结果显示,共检测到642个DE RNA(457个mRNA和185个lncRNA)和256个DE蛋白质。DE mRNA(如 、 和 )在与氧化还原过程相关的功能中富集。PPI网络由175个节点和425条边组成。VEGFA是一个具有最高度的重要节点。为具有超过15个基因靶点的lncRNA构建了具有三个子网(C1、C2、C3)的lncRNA-mRNA网络。RP11-58O9.2是一个具有最多靶基因的重要lncRNA,RP11-667F14.1调控超过20个靶点。 是这两个lncRNA的共同靶点。功能分析表明,DE lncRNA参与了HTLV-I感染(RP11-58O9.2和RP11-667F14.1)和IL-17信号通路(RP11-5O24.1和RP11-58O9.2)。共有11个DE mRNA与DE蛋白质重叠,其中MAOB和SDR16C5在mRNA和蛋白质表达之间呈正相关。功能分析表明, 在氧化还原过程中富集,其蛋白质与对脂多糖的反应密切相关。 、 、 、 、RP11-58O9.2、RP11-667F14.1和RP11-288A5.2可能作为预防食管癌支架再狭窄的基因靶点。
