α-pinene (Figure 9E) showed moderately strong cytoplasmic positivity for VEGF in the ductal epithelial cells and β-pinene (Figure 9F) depicted moderately strong cytoplasmic positivity for VEGF in the ductal epithelial cells, which mean that these isomers have less affinity toward the VEGF receptors and thus are unable to cause the apoptotic action in tumor tissues. Here, VEGFA is linked to neoplasm.
