There are many available software tools for visualization and analysis of biological networks. Among them, Cytoscape ( http://cytoscape.org/ ) is one of the most comprehensive packages, with many plugins and applications which extends its functionality by providing analysis of protein-protein interaction, gene regulatory and gene co-expression networks, metabolic, signaling, neural as well as ecological-type networks including food webs, communities networks etc. Nevertheless, only three plugins tagged 'network evolution' found in Cytoscape official app store and in literature. We have developed a new Cytoscape 3.0 application Orthoscape aimed to facilitate evolutionary analysis of gene networks and visualize the results.
Orthoscape aids in analysis of evolutionary information available for gene sets and networks by highlighting: (1) the orthology relationships between genes; (2) the evolutionary origin of gene network components; (3) the evolutionary pressure mode (diversifying or stabilizing, negative or positive selection) of orthologous groups in general and/or branch-oriented mode. The distinctive feature of Orthoscape is the ability to control all data analysis steps via user-friendly interface.
Orthoscape allows its users to analyze gene networks or separated gene sets in the context of evolution. At each step of data analysis, Orthoscape also provides for convenient visualization and data manipulation.
有许多可用的软件工具用于生物网络的可视化和分析。其中,Cytoscape(http://cytoscape.org/)是最全面的软件包之一,它有许多插件和应用程序,通过提供蛋白质-蛋白质相互作用、基因调控和基因共表达网络、代谢、信号传导、神经以及包括食物网、群落网络等在内的生态型网络的分析来扩展其功能。然而,在Cytoscape官方应用商店和文献中仅发现三个标记为“网络进化”的插件。我们开发了一个新的Cytoscape 3.0应用程序Orthoscape,旨在促进基因网络的进化分析并可视化结果。
Orthoscape通过突出显示以下内容来辅助分析基因集和网络的进化信息:(1)基因之间的直系同源关系;(2)基因网络组件的进化起源;(3)直系同源组的进化压力模式(多样化或稳定化、负选择或正选择),总体上和/或以分支导向模式。Orthoscape的独特之处在于能够通过用户友好的界面控制所有数据分析步骤。
Orthoscape允许用户在进化背景下分析基因网络或分离的基因集。在数据分析的每个步骤中,Orthoscape还提供方便的可视化和数据操作。
