Fig. 3From: Whole Transcriptome Analysis of Pre-invasive and Invasive Early Squamous Lung Carcinoma in Archival Laser Microdissected SamplesIngenuity pathway analysis (IPA) of aberrant transcription in PSCC and ISCC. (i) The first heatmap column shows all IPA pathways that are significantly affected in ISCC (p-value < =0.05). The remaining 3 columns indicate the association of these IPA pathways with differentially expressed genes in all PSCC, high-grade PSCC or low-grade PSCC. (ii) This heatmap summarise the connection between IPA pathways significantly related to gene expression changes in ISCC (p-value < =0.05) and genes sorted by cluster analysis. Note that genes from cluster 8 were not linked to any IPA pathways associated with ISCCBack to article page
