Due to the finding that the highest expression of NEAT1 was detected in HeLa cells and the lowest expression was detected in SiHa cells among the four cervical cancer cell lines detected, we transfected HeLa and SiHa cells with two independent siRNAs targeting NEAT1 (si‐NEAT1‐1# and si‐NEAT1‐2#) and NEAT1‐expressing pcDNA3.1 plasmids to establish NEAT1‐knockdown and NEAT1‐overexpressing cell models, respectively, and confirmed the efficiency of the transfection with RT–qPCR (Figure 1B,C). This evidence concerns the gene NEAT1 and cervical carcinoma.
