Fig. 1From: Circular RNA KIF4A promotes cell migration, invasion and inhibits apoptosis through miR-152/ZEB1 axis in breast cancerHigh expression of circKIF4A in BC tissues and cells. (a) The level of circKIF4A in BC tissues and normal tissues was evaluated using qRT-PCR. (b) The expression of circKIF4A in MCF-7, MDA-MB-231 and MCF-10A cells was determined using qRT-PCR. ***P < 0.001Back to article page
