Expression of venom protein genes during IJ activation.

<p><b>(A)</b> A heatmap showing the mean-centered gene expression counts of 472 venom protein genes across activated and non-activated IJs. Protein products of these genes were detected with mass spectrometry in the venom from 12 hr <i>in vitro</i> activated IJs. DE, differentially expressed. The green and red colored rows in the DE column represent the upregulated and downregulated genes in activated IJs, which are used in (B). <b>(B)</b> Venn diagrams showing the venom protein genes that are transcriptionally upregulated or downregulated in activated IJs relative to non-activated IJs, and their breakdown by activation method (12 hr <i>in vitro</i> and 15 hr <i>in vivo</i>). <b>(C)</b> maSigPro plots showing venom protein genes that are differentially expressed over the 15 hr <i>in vivo</i> activation time course.
