ABSTRACT
Recently, numerous studies have revealed the participation of circular RNAs (circRNAs) in cancer progression. Likewise, this research focused on circRNAs in hepatocellular carcinoma (HCC). A lowly expressed circRNA hsa_circ_0072309 in HCC was screened by analyzing the circRNA microarray GSE242797 and GSE216115 and identified in clinical specimens and cells. Subsequently, CCK-8, colony formation, and transwell assays were performed. The results revealed that hsa_circ_0072309 overexpression suppressed HCC cell proliferation, migration, invasion, and sorafenib resistance, whereas its suppression showed opposite results. Mechanistic investigation found an interaction between hsa_circ_0072309 and its host gene leukemia inhibitory factor receptor (LIFR) in HCC. We found that LIFR overexpression promoted the hsa_circ_0072309 formation. In turn, hsa_circ_0072309 recruited the E1A binding protein p300 to promote the enrichment of H3K27 acetylation (H3K27ac) in the LIFR enhancer, thus transcriptionally promoting LIFR expression. To conclude, we revealed a hsa_circ_0072309/LIFR regulatory loop in HCC, which may provide a potential target for HCC treatment.
