HIF1A and renal carcinoma: The si-HIF1A-AS2 co-transfected miR-30a-5p mimics better suppressed renal carcinoma cell proliferation (Figure 4C–4F) and migration (Figure 4G and 4H) than the si-NC co-transfection with NC (si-NC+NC), and compared with the si-NC+NC group, apoptosis was increased in the si-HIF1A-AS2 co-transfection miR-30a-5p mimics (si-HIF1A-AS2+miR-30a-5p) group (Figure 4I and 4J).
