The wealth of publicly available gene expression and genomic data provides unique opportunities for computational inference to discover groups of genes that function to control specific cellular processes. Such genes are likely to have co-evolved and be expressed in the same tissues and cells. Unfortunately, the expertise and computational resources required to compare tens of genomes and gene expression data sets make this type of analysis difficult for the average end-user. Here, we describe the implementation of a web server that predicts genes involved in affecting specific cellular processes together with a gene of interest. We termed the server 'EvoCor', to denote that it detects functional relationships among genes through evolutionary analysis and gene expression correlation. This web server integrates profiles of sequence divergence derived by a Hidden Markov Model (HMM) and tissue-wide gene expression patterns to determine putative functional linkages between pairs of genes. This server is easy to use and freely available at http://pilot-hmm.vbi.vt.edu/.
大量公开的基因表达和基因组数据为计算推理提供了独特的机会,可以发现控制特定细胞过程的基因群。这些基因可能是共同进化的,并在相同的组织和细胞中表达。不幸的是,比较数十个基因组和基因表达数据集所需的专业知识和计算资源使得这种类型的分析对于普通用户来说很困难。在这里,我们描述了一个网络服务器的实现,该服务器可以预测与感兴趣基因一起参与影响特定细胞过程的基因。我们将该服务器命名为“EvoCor”,表示它通过进化分析和基因表达相关性来检测基因之间的功能关系。这个网络服务器集成了由隐马尔可夫模型(HMM)推导的序列分歧轮廓和组织范围的基因表达模式,以确定基因对之间的假定功能联系。这个服务器易于使用,并且可以在 http://pilot-hmm.vbi.vt.edu/ 免费获得。
