Compared with cells treated with siRNA‐NC, HULC siRNA‐transfected HCC cells have a significant increase in level of miR‐107 quantified by Quantitative Real‐time Polymerase Chain Reaction (qRT‐PCR), and a reduction of HULC expression was found after miR‐107 mimic introduction (Figures 3B and 3C). This evidence concerns the gene HULC and hepatocellular carcinoma.
