The lncRNAs SLC7A11-AS1 and hsa_circ_0006123 may be related to the metastasis of HCC. Expression levels of three selected lncRNA s (A) and three selected circRNAs (B) in 81 pairs of HCC samples and adjacent non-cancerous tissues using qRT-PCR. Expression levels of three selected lncRNAs (C) and three selected circRNAs (D) in patients with vascular invasion (Tumor-M) and patients without vascular invasion (Tumor-N). (E) Analysis of the lncRNA SLC7A11-AS1 expression level in TCGA liver cancer samples. (F) Kaplan–Meier analysis of overall survival in liver cancer patients stratified according to their SLC7A11-AS1 expression levels in the TCGA liver cancer cohort. (G) Kaplan–Meier analysis of diseases-free survival of liver cancer patients stratified according to their lncRNA SLC7A11-AS1 expression levels in the TCGA liver cancer cohort.
