SNAI3‐AS1 was overexpressed in HCC tissues and cell lines. (A) qRT‐PCR analysis of SNAI3‐AS1 expression in 46 patients with HCC and matched adjacent normal tissues. **P < 0.01. (B) qRT‐PCR analysis of SNAI3‐AS1 expression in HCC cell lines and the immortalized human hepatic cell line LO2, *P < 0.05; **P < 0.01. (C,D) Kaplan‐Meier analysis of OS and RFS based on SNAI3‐AS1 expression levels in HCC patients. The median level of SNAI3‐AS1 is used as the cut‐off. Patients with HCC are divided into a high‐expression group and a low‐expression group
