VEGFA and Hyperglycemia: qRT-PCR validation showed upregulation of VEGFA upon exposure to CoCl2 at 3 and 12 h under euglycemia-CoCl2 (7.2-fold, p = 0.017 and 9.4-fold, p = 0.002 respectively versus no CoCl2), and hyperglycemia-CoCl2 (7.4-fold, p = 0.015 and 8.4-fold, p = 0.005 respectively versus hyperglycemia alone) as illustrated in Figure 4A.
