Heat map and hierarchical clustering of the microarray data. Xiao Liu Zhiwen Xu Ling Zhu Shan Liao Wanzhu Guo 10.1371/journal.pone.0113921.g003 https://plos.figshare.com/articles/figure/_Heat_map_and_hierarchical_clustering_of_the_microarray_data_/1251324 <p>Hierarchical clustering was used to analyze the gene expression data by arranging the samples into groups based on their expression levels. The dendrogram shows the relationships among the gene expression patterns in the samples. The red line indicates high relative expression and the green line indicates low relative expression.</p> 2014-11-25 02:43:29 host transcriptional response gene interaction networks Porcine Cytomegalovirus Infection Porcine cytomegalovirus PCMV infection KEGG pathway analysis mechanism tgf tnf
