The results showed that the number of tumours and the proportion of tumour stem cells were lower in the si‐NEK2 group compared with those in the corresponding NC group; compared with those in the miR‐128‐3p inhibitor + si‐NEK2‐NC group, the number of tumours and the proportion of tumour stem cells were low in the miR‐128‐3p inhibitor + si‐NEK2 group (Table 4, Figure 10A). This evidence concerns the gene NEK2 and neoplasm.
