Knockdown of lncRNA SLC7A11-AS1 and hsa_circ_0006123 suppresses the migration and invasion of Huh7 cell. Migration and invasion of Huh7 following treatment with si-lncRNA SLC7A11-AS1 (A) or si-hsa_circ_0006123 (B). Relative protein levels of EMT markers in Huh7 cells following treatment with si-lncRNA LC7A11-AS1 (C) or si-hsa_circ_0006123 (D). qRT-PCR analysis showed that mRNA expression of lncRNA SLC7A11-AS1 and hsa_circ_0006123 were positively correlated with the ZEB1 (E) and snail1 (F) mRNA in 81 HCC patients
