摘要:

来自分子系统生物学领域的流行在线富集分析工具为用户提供了将其实验结果作为基因集提交以进行个体分析的能力。这些查询是保密的,以前从未被认为是综合分析的资源。通过利用成千上万用户提交的基因集查询,我们的目标是发现超出个人研究范围的生物学知识。在这项工作中,我们调查了数千名用户提交给Enrichr工具的大量基因集。基于共现原理,我们构建了一个全局基因-基因关联网络。我们解释这个推断的网络提供了一个总结的结构存在于这个众包基因集库,并表明,这个网络概括了已知的蛋白质相互作用和基因之间的功能关联。这一发现意味着该网络也提供了预测价值。此外,我们使用一种新的边缘修剪算法来可视化这个基因-基因关联网络,该算法保留了大规模网络的局部和全局结构。我们有能力对目前未知的基因关联进行预测,这可能不会被个别研究人员和数据源捕获,这证明了利用分子系统生物学领域流行工具用户的集体知识的潜力。

英文摘要:

Popular online enrichment analysis tools from the field of molecular systems biology provide users with the ability to submit their experimental results as gene sets for individual analysis. Such queries are kept private, and have never before been considered as a resource for integrative analysis. By harnessing gene set query submissions from thousands of users, we aim to discover biological knowledge beyond the scope of an individual study. In this work, we investigated a large collection of gene sets submitted to the tool Enrichr by thousands of users. Based on co-occurrence, we constructed a global gene-gene association network. We interpret this inferred network as providing a summary of the structure present in this crowdsourced gene set library, and show that this network recapitulates known protein-protein interactions and functional associations between genes. This finding implies that this network also offers predictive value. Furthermore, we visualize this gene-gene association network using a new edge-pruning algorithm that retains both the local and global structures of large-scale networks. Our ability to make predictions for currently unknown gene associations, that may not be captured by individual researchers and data sources, is a demonstration of the potential of harnessing collective knowledge from users of popular tools in the field of molecular systems biology.
