肺腺癌(LADC)和鳞癌(LSCC)是最常见的非小细胞肺癌组织表型。对这两种类型肺癌的准确鉴别诊断具有临床意义。在这项研究中,我们分析了四个基因表达总括(GEO)数据集(GSE28571、GSE37745、GSE43580和GSE50081)。然后,我们将数据集导入到基因云生物技术信息在线平台,以确定在LADC和LSCC中差异表达的基因。我们确定DSG3(桥粒芯糖蛋白3)、Krt5(角蛋白5)、KRT6A(角蛋白6A)、KRT6B(角蛋白6B)、NKX2-1(NK2同源盒1)、SFTA2(表面活性物质相关2)、SFTA3(表面活性物质相关3)和TMC5(跨膜通道样蛋白5)是区分LADC和LSCC的潜在生物标志物。受试者工作特征曲线分析表明,Krt5对这两种癌症的鉴别诊断价值最高。使用PrognoScan在线生存分析工具和Kaplan-Meier绘图仪,我们发现高KRT6A或KRT6B水平或低NKX2-1、SFTA3或TMC5水平与LADC患者预后不良相关。还需要进一步的研究来验证我们在更多患者样本中的发现,并阐明这些潜在的生物标记物在非小细胞肺癌中的作用机制。
Lung adenocarcinoma (LADC) and squamous cell carcinoma (LSCC) are the most common non-small cell lung cancer histological phenotypes. Accurate diagnosis distinguishing between these two lung cancer types has clinical significance. For this study, we analyzed four Gene Expression Omnibus (GEO) datasets (GSE28571, GSE37745, GSE43580, and GSE50081). We then imported the datasets into the Gene-Cloud of Biotechnology Information online platform to identify genes differentially expressed in LADC and LSCC. We identified DSG3 (desmoglein 3), KRT5 (keratin 5), KRT6A (keratin 6A), KRT6B (keratin 6B), NKX2-1 (NK2 homeobox 1), SFTA2 (surfactant associated 2), SFTA3 (surfactant associated 3), and TMC5 (transmembrane channel-like 5) as potential biomarkers for distinguishing between LADC and LSCC. Receiver operating characteristic curve analysis suggested that KRT5 had the highest diagnostic value for discriminating between these two cancer types. Using the PrognoScan online survival analysis tool and the Kaplan-Meier Plotter, we found that high KRT6A or KRT6B levels, or low NKX2-1, SFTA3, or TMC5 levels correlated with unfavorable prognoses in LADC patients. Further studies will be needed to verify our findings in additional patient samples, and to elucidate the mechanisms of action of these potential biomarkers in non-small cell lung cancer.
