HIF1A and neoplasm: Figure 5 shows quantitative results on mRNA expression of genes HIF-1α, VEGF-A, GLUT1, AhR, ARNT, and CYP1B1 in the cells that were exposed to 200 μM CoCl2.The exposure of the patient-derived nonembolized tumor primary cells to hypoxic conditions—as expected—increased the expression of HIF-1α mRNA fourfold in comparison with the control cell culture but did not change the mRNA expression of HIF-1α target genes: VEGF-A and GLUT1 (Figure 5).
