Figure 4.
Graphs and photomicrograph representing the relative levels of gene expression by quantitative real-time PCR in ORF virus infected and healthy control lambs and kids. (a–e). Gene expression relative quantification of host vascular endothelial growth factor receptor 2 (VEGFR2), vascular endothelial growth factor receptor 1 (VEGFR1), vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), and interleukin-6 (IL-6). Statistically significant overexpression was found only for VEGFR1, VEGFR2, and IL-6 when compared with the healthy controls. Values were normalized to the expression levels of the sheep 18s rRNA and β-actin (ACTB) and expressed as relative fold change compared to the expression levels of one of the healthy controls. (f) Representative image of the IL-6 mRNA localization in the dermis. In situ hybridization for IL-6 mRNA.
