Then, we extracted the RNA and protein from the tumour tissues derived from the sh‐NEAT1 and sh‐NC groups, and detected the expression levels of NEAT1 and miR‐193a by qRT‐PCR and that of PCNA by Western blot analysis, which indicated that NEAT1 expression was decreased (Figure 6E), but miR‐193a expression was increased (Figure 6F) in sh‐NEAT1 group as compared to sh‐NC, and knockdown of NEAT1 downregulated the expression of PCNA in tumour tissues compared with the sh‐NC group (Figure 6G). The gene discussed is PCNA; the disease is neoplasm.
