染色质相互作用在基因表达调控中起重要作用。然而,全基因组染色质相互作用数据的可用性是有限的。我们开发了一种计算方法,染色质相互作用神经网络(ChINN),仅使用DNA序列来预测开放染色质区域之间的染色质相互作用。ChINN预测CTCF和RNA聚合酶II相关和Hi-C染色质相互作用。ChINN显示出良好的跨样本性能,并捕获用于染色质相互作用预测的各种序列特征。我们将ChINN应用于6例慢性淋巴细胞白血病(CLL)患者样本和84例CLL开放染色质样本的已发表队列。我们的研究结果表明CLL患者样本中染色质相互作用的广泛异质性。在线版本包含补充材料,可通过10.1186/s13059-021-02453-5获得。
Chromatin interactions play important roles in regulating gene expression. However, the availability of genome-wide chromatin interaction data is limited. We develop a computational method, chromatin interaction neural network (ChINN), to predict chromatin interactions between open chromatin regions using only DNA sequences. ChINN predicts CTCF- and RNA polymerase II-associated and Hi-C chromatin interactions. ChINN shows good across-sample performances and captures various sequence features for chromatin interaction prediction. We apply ChINN to 6 chronic lymphocytic leukemia (CLL) patient samples and a published cohort of 84 CLL open chromatin samples. Our results demonstrate extensive heterogeneity in chromatin interactions among CLL patient samples. The online version contains supplementary material available at 10.1186/s13059-021-02453-5.
