The data indicated that both of the two selected siRNAs could significantly decrease ZFAS1 expression as shown in Figure 2B. In that case, CCK‐8 and colony formation assays were performed and the results indicated that compared with siRNA of negative control (si‐NC), silence of ZFAS1 significantly suppressed cell growth (Figure 2C), and the tumour cell colonies formed troublesomely for the very inhibition of ZFAS1 (Figure 2D). This evidence concerns the gene ZFAS1 and neoplasm.
