Self-transcribing active regulatory region sequencing (STARR-seq) is a high-throughput sequencing method capable of simultaneously discovering and validating all enhancers within the genome. In this method, candidate sequences are inserted into plasmid vectors and electroporated into cells. Acting as both enhancers and target genes, the self-transcription of these sequences will also be enhanced by themselves. By sequencing the transcriptome and comparing the results with the non-inserted control, the locations and activity of enhancers can be determined. In traditional enhancer discovery strategies, the chromatin open regions and transcription active regions were sequenced and predicted as enhancers. However, the activity of these putative enhancers could only be validated one by one without a high-throughput method. STARR-seq solved this limitation, allowing simultaneous enhancers discovery and activity validation in a high-throughput manner. Since the introduction of STARR-seq, it has been widely used to discover enhancers and validate enhancer activity in a number of organisms and cells. In this review, we present the traditional enhancer prediction methods and the basic principles, development history, specific applications of STARR-seq, and its future prospects, aiming to provide a reference for researchers in related fields conducting enhancer studies.

自转录活性调控区测序(STARR-seq)是一种高通量测序方法,能够同时发现和验证基因组内的所有增强子。在这种方法中,候选序列被插入质粒载体并电穿孔到细胞中。这些序列既是增强子又是靶基因,其自身转录也会增强。通过对转录组进行测序,并将结果与未插入的对照进行比较,可以确定增强子的位置和活性。在传统的增强子发现策略中,染色质开放区和转录活性区被测序并预测为增强子。然而,在没有高通量方法的情况下,这些假定增强子的活性只能逐个验证。STARR-seq 解决了这一限制,可以高通量方式同时发现增强子并验证其活性。自 STARR-seq 问世以来,它已被广泛用于发现增强子,并在许多生物和细胞中验证增强子的活性。在这篇综述中,我们介绍了传统的增强子预测方法和 STARR-seq 的基本原理、发展历程、具体应用及其未来前景,旨在为相关领域的研究人员开展增强子研究提供参考。

Inference and prioritization of tissue-specific regulons in Arabidopsis and Oryza 拟南芥和旱生植物组织特异性调控子的推断和优先排序

A regulon refers to a group of genes regulated by a transcription factor binding to regulatory motifs to achieve specific biological functions. To infer tissue-specific gene regulons in Arabidopsis, we developed a novel pipeline named InferReg. InferReg utilizes a gene expression matrix that includes 3400 Arabidopsis transcriptomes to make initial predictions about the regulatory relationships between transcription factors (TFs) and target genes (TGs) using co-expression patterns. It further improves these anticipated interactions by integrating TF binding site enrichment analysis to eliminate false positives that are only supported by expression data. InferReg further trained a graph convolutional network with 133 transcription factors, supported by ChIP-seq, as positive samples, to learn the regulatory logic between TFs and TGs to improve the accuracy of the regulatory network. To evaluate the functionality of InferReg, we utilized it to discover tissue-specific regulons in 5 Arabidopsis tissues: flower, leaf, root, seed, and seedling. We ranked the activities of regulons for each tissue based on reliability using Borda ranking and compared them with existing databases. The results demonstrated that InferReg not only identified known tissue-specific regulons but also discovered new ones. By applying InferReg to rice expression data, we were able to identify rice tissue-specific regulons, showing that our approach can be applied more broadly. We used InferReg to successfully identify important regulons in various tissues of Arabidopsis and Oryza, which has improved our understanding of tissue-specific regulations and the roles of regulons in tissue differentiation and development.

调控子是指通过转录因子与调控基序结合来实现特定生物功能的一组基因。为了推断拟南芥组织特异性基因调控子,我们开发了一个名为 InferReg 的新管道。 InferReg 利用包含 3400 个拟南芥转录组的基因表达矩阵,通过共表达模式初步预测转录因子(TF)和靶基因(TG)之间的调控关系。通过整合 TF 结合位点富集分析,它进一步改进了这些预期的相互作用,以消除仅由表达数据支持的假阳性。InferReg 还以 ChIP-seq 支持的 133 个转录因子为阳性样本,进一步训练图卷积网络,以学习 TF 与 TG 之间的调控逻辑,从而提高调控网络的准确性。为了评估 InferReg 的功能,我们利用它发现了拟南芥 5 个组织(花、叶、根、种子和幼苗)中的组织特异性调控子。我们使用博尔达排序法根据可靠性对每个组织的调控子的活性进行了排序,并与现有数据库进行了比较。结果表明,InferReg 不仅能识别已知的组织特异性调控子,还能发现新的组织特异性调控子。通过将 InferReg 应用于水稻表达数据,我们能够识别水稻组织特异性调控子,这表明我们的方法可以更广泛地应用。我们利用 InferReg 成功鉴定了拟南芥和芸苔属植物不同组织中的重要调控子,从而加深了我们对组织特异性调控以及调控子在组织分化和发育中的作用的理解。
