Compared to 293T cells, the relative expression of HIF1A-AS2 was significantly upregulated in kidney carcinoma cells, 786-O (approximately 4.200-fold, P < 0.01), ACHN cells (approximately 5.184-fold, P < 0.01), and OS-RC-2 cells (approximately 1.998-fold, P < 0.001) (Figure 1E–1G). Here, HIF1A is linked to renal carcinoma.
