Gene expression analysis of the python ventricle. (A) The location from which tissue was collected (ventral side). (B) Diagram indicating the enrichment of genes in either the right or left side of the ventricle. (C) Scatter plot showing for each gene the statistical significance on the y axis and the magnitude of change on the x axis. (D) A heat map showing four clusters of the relative expression of genes between the right and left side of the ventricle. (E) KEGG pathway analysis for each of the four clusters. LV, left ventricle; Mid, mid ventricle; RV, right ventricle.
