Figure 4. Enrichment Analysis: heatmap visualization of proteins encoded by genes of of human chromosome 18 identified in SDS-treated samples of HaCaT human keratinocytes using the Metascape database (http://metascape.org). A heatmap using a discrete color scale illustrating statistical significance is presented for the main enrichment clusters of Gene Ontology (GO) in the biological processes category. Gray color indicates lack of significance.
