VEGF pathway, tumor. Heatmap of genes in the VEGF signaling pathway (HSA04370). The table display gene names, systematic names, and fold change of gene expression compared to control of intermittent (I) and daily (D) hyperbaric oxygen (HBO), respectively. The VEGF pathway is significantly down-regulated by intermittent HBO treatment of 4T1 mammary tumor cells, but not by daily treatment. NS = not significant.
