目的 探讨染色质调节因子(CRs)在乳腺癌中的差异表达及其对预后的预测价值.方法 利用癌症基因组图谱数据库筛选乳腺癌和正常乳腺组织中差异表达的CRs,并通过最小绝对值收敛和选择算子算法-Cox回归分析构建预后风险模型,根据风险分数(Risk score)将乳腺癌患者分为高风险组和低风险组;同时分析风险模型与乳腺癌患者临床特征的相关性,并对每个基因进行单独验证.结果 本研究识别了 127个在乳腺癌中差异表达的CRs,并基于16个关键CRs构建了预后风险模型;低风险组患者中年龄≤65岁、Stage Ⅰ~Ⅱ期、Ⅲ~Ⅳ期、T0~T1、T2~T3、N0~N1、N2~N3者总生存期均高于高风险组(均P<0.05).结论 CRs能预测乳腺癌患者的预后.
Differential expression of chromatin regulators in breast cancer and its value for prognosis of patients
Objective To investigate the differential expression of chromatin regulators(CRs)in breast cancer(BRCA)and their prognostic value.Methods The data of differentially expressed chromatin regulators between breast cancer and normal breast tissues were obtained from The Cancer Genome Atlas database.A prognostic risk model was constructed through LASSO-Cox regression analysis.The association between the risk model and the clinical features of breast cancer patients was analyzed,and individual validation for each gene was conducted.Finally,potential small molecule drugs targeting chromatin regulators were screened.Results A total of 127 differentially expressed chromatin regulators were identified,and a prognostic risk model based on 16 CRs were successfully constructed.The model demonstrated excellent accuracy in predicting the prognosis of breast cancer patients(P<0.05).Moreover,the risk model exhibited significant performance in relation to clinical features.Ultimately,ten potential therapeutic compounds were predicted,with choline being the most noteworthy.Conclusion The study has identified differentially expressed CRs in breast cancer and their roles in predicting prognosis of patients.
