摘要:

目的 探讨自噬凋亡在子宫内膜癌(UCEC)中的潜在机制,分析自噬凋亡对生存预后的影响。方法 基因组测序数据来自癌症基因组图谱(The Cancer Genome Atlas,TCGA)数据库和基因型组织表达(Genotype-Tissue Expression,GTEx)数据库,筛选获得UCEC相关的差异表达基因及UCEC生存预后相关的关键自噬基因,然后构建并验证UCEC患者生存预后的风险评分预测模型,分析自噬凋亡对UCEC生存预后的影响。结果 共筛选出1 964个差异表达基因,包含631个(32.13%)上调基因、1 333个(67.87%)下调基因,其中21个子宫内膜癌相关自噬差异表达基因(UCEC-AT-DEGs)。Kaplan-Meier生存分析结果显示,EIF4EBP1、CDKN2A、VEGFA基因的表达升高,均导致UCEC总生存期缩短(均P<0.05)。决策树分析(DCA)曲线显示:EIF4EBP1对UCEC的2年、3年生存率影响具有较高的临床应用价值。LASSO回归结果显示,风险评分Riskscore = 0.139 5×EIF4EBP1 + 0.182 7×CDKN2A + 0.079 1×ITPR1 + 0.265 8×GRID1 - 0.018 7×TM9SF1 - 0.125 0×RAB24 + 0.071 0×VEGFA(λmin=0.017 2),该模型具有可靠的预测性能。EIF4EBP1表达水平与顺铂的半数最大抑制浓度(IC50)呈负相关,CDKN2A表达水平与紫杉醇和顺铂的IC50均呈负相关(均P<0.05)。结论 多个自噬基因在UCEC中的表达变化明显,部分关键自噬基因的异常高表达对UCEC患者的总生存率产生不良影响;EIF4EBP1、CDKN2A对UCEC的2年、3年生存率影响具有较高的临床应用价值,并对一线化疗药物的效果产生一定影响。

Abstract: Objective To explore the potential mechanism of autophagy apoptosis in uterine corpus endometrial carcinoma (UCEC) and analyze the impact of autophagy apoptosis on its survival prognosis. Methods Genomic sequencing data were derived from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases. Differentially expressed genes related to UCEC and key autophagy genes related to UCEC survival prognosis were screened. Then, a risk scoring prediction model for survival prognosis in UCEC patients was constructed and validated, and the impact of autophagy apoptosis on UCEC survival prognosis was analyzed. Results A total of 1 964 differentially expressed genes were screened, including 631 (32.13%) upregulated genes and 1 333 (67.87%) downregulated genes, among which there were 21 uterine corpus endometrial carcinoma associated autophagy differentially expressed genes (UCEC-AT-DEGs). Kaplan-Meier survival analysis results showed that the increased expressions of EIF4EBP1, CDKN2A, and VEGFA genes all led to a shorter overall survival period of UCEC (all P<0.05). The decision curve analysis (DCA) curve showed that EIF4EBP1 had a greater clinical application value in influencing the 2-year and 3-year survival rates of UCEC. The LASSO regression results showed that Riskscore = 0.139 5× EIF4EBP1 + 0.182 7×CDKN2A + 0.079 1×ITPR1 + 0.265 8×GRID1 - 0.018 7×TM9SF1 - 0.125 0× RAB24 + 0.071 0×VEGFA (λmin=0.017 2), and this model had reliable predictive performance. The expression level of EIF4EBP1 was negatively correlated with the maximum half inhibitory concentration (IC50) of cisplatin, and the expression level of CDKN2A was negatively correlated with the IC50 of paclitaxel and cisplatin (all P<0.05). Conclusions The expressions of multiple autophagy genes significantly changed in UCEC, and the abnormal high expressions of some key autophagy genes had an adverse impact on the overall survival rate of UCEC patients. EIF4EBP1 had a greater clinical application value in influencing the 2-year and 3-year survival rates of UCEC. The signature model of UCEC survival prognosis established in this study had reliable predictive performance.
