VEGFA and infection: While infection of shRL cells exhibited a steady increase in VEGF-A supernatant levels at 8 and 24 hr p.i. (Fig. 7C, black line), infection of shNrf2 displayed only a moderate increase in VEGF-A supernatant levels (Fig. 7C, red line), further confirming the importance of Nrf2 in VEGF-A expression.
