Understanding the regulatory mechanisms of gene expression is a crucial objective in genomics. Although the DNA sequence near the transcription start site (TSS) offers valuable insights, recent methods suggest that analyzing only the surrounding DNA may not suffice to accurately predict gene expression levels. We developed GENet (Gene Expression Network from Histone and Transcription Factor Integration), a novel approach that integrates essential regulatory signals from transcription factors and histone modifications into a graph-based model. GENet extends beyond simple DNA sequence analysis by incorporating additional layers of genetic control, which are vital for determining gene expression. Our method markedly enhances the prediction of mRNA levels compared to previous models that depend solely on DNA sequence data. The results underscore the significance of including comprehensive regulatory information in gene expression studies. GENet emerges as a promising tool for researchers, with potential applications extending from fundamental biological research to the development of medical therapies.
理解基因表达的调控机制是基因组学的一个关键目标。尽管转录起始位点(TSS)附近的 DNA 序列提供了有价值的见解,但最近的方法表明,仅分析周围的 DNA 可能不足以准确预测基因表达水平。我们开发了 GENet(基于转录因子和组蛋白修饰整合的基因表达网络),这是一种新颖的方法,它将转录因子和组蛋白修饰的基本调控信号整合到基于图的模型中。GENet 通过纳入对确定基因表达至关重要的额外遗传控制层,超越了简单的 DNA 序列分析。与仅依赖 DNA 序列数据的先前模型相比,我们的方法显著提高了 mRNA 水平的预测能力。这些结果强调了在基因表达研究中纳入全面调控信息的重要性。GENet 是研究人员的一个有前途的工具,其潜在应用从基础生物学研究扩展到医学治疗的发展。
