RESULTS: Here, we propose a new method, consensus mutual information (CoMI) for analyzing omics data and discovering gene signatures. CoMI can identify differentially expressed genes in multiple cancer omics data for reflecting both cancer-related and tissue-specific signatures, such as Cell growth and death in multiple cancers, Xenobiotics biodegradation and metabolism in LIHC, and Nervous system in GBM. Our method identified 50-gene signatures effectively distinguishing the GBM patients into high- and low-risk groups (log-rank p = 0.006) for diagnosis and prognosis.
CONCLUSIONS: Our results demonstrate that CoMI can identify significant and consistent gene signatures with tissue-specific properties and can predict clinical outcomes for interested diseases. We believe that CoMI is useful for analyzing omics data and discovering gene signatures of diseases.
结果:这里,我们提出了一种新的方法,用于分析组学数据和发现基因特征的共识互信息(CoMI)。CoMI可以识别多个癌症组学数据中的差异表达基因,以反映癌症相关和组织特异性特征。如多种癌症的细胞生长和死亡,LIHC中的异种生物的生物降解和代谢,和GBM中的神经系统。我们的方法鉴定了50个基因特征,有效地将GBM患者分为高危组和低危组(log-rankp=0.006)进行诊断和预后。
结论:我们的结果表明,CoMI可以识别具有组织特异性的显著且一致的基因特征,并可以预测感兴趣的疾病的临床结果。我们相信CoMI对于分析组学数据和发现疾病的基因特征很有用。
