Figure 2. Over-expression of HNF1A-AS1 suppressed cell viability. (A) The transfection rate of HNF1A-AS1 plasmids was validated by qRT-PCR. (B, C) CCK8 was performed to analyze the growth rate of GEP-NENs cells transfected with HNF1A-AS1 over-expression plasmid or control (EV). (D) The colony formation ability of GEP-NENs cells transfected with HNF1A-AS1 or EV was determined.*p < 0.05, **p < 0.01.
