Fig. 1. lncRNA HEPFAL is downregulated in HCC, indicating a poor prognosis, and SLC7A11 is up-regulated.
A The expression of lncRNA HEPFAL in HCC is lower than that in normal tissues (n = 368 in TCGA database). B The expression of SLC7A11 in HCC is higher than that in normal tissues (n = 368 in TCGA database). C Based on the median expression of lncRNA HEPFAL, patients were divided into high-expression and low-expression groups, and the Kaplan–Meier survival curve of 368 HCC patients was drawn. D, E qRT-PCR detects the expression of lncRNA HEPFAL in tumor tissues and matched normal tissues (n = 60 in WMU hospital). F Kaplan–Meier survival curve of overall survival in 60 HCC patients according to the lncRNA HEPFAL expression. Patients were stratified into high and low expression groups by median expression. G, H qRT-PCR detects the expression of lncRNA HEPFAL and SLC7A11. I The expression of SLC7A11 was detected by western blot. J IHC detected SLC7A11 expression in tumor tissues with high and low lncRNA HEPFAL expression. ***P < 0.001.
