Figure 2From: Altered expression of mitochondrial and extracellular matrix genes in the heart of human fetuses with chromosome 21 trisomyVolcano plot of genes differentially expressed between trisomic and control samples. The log2 of fold change between trisomic and control samples is represented on the x-axis and the negative log of p-values from the t-test is represented on the y-axis. Genes upregulated in the trisomic samples are on the right of the horizontal axis 0 value; genes downregulated are on the left. Red dots indicate 473 genes that are significantly up- or down-regulated in the trisomic samples compared to the control samples (p < 0.05). Yellow dots indicate genes with no significant variation.Back to article page
