Abstract	The pro-oncogene factor that binds to inducer of short transcripts-1 (FBI-1), which is encoded by ZBTB7A gene and belongs to POK (POZ/BTB and KrÜppel) protein family, has been shown to enhance hepatocellular carcinoma (HCC) cells proliferation and multi-drug resistance (MDR) process. However, the possibility that FBI-1 is a therapeutic target for further HCC treatment remains poorly determined. In the current study, two microRNA (miRNA) target prediction programs (TargetScan and MiRanda) were used to identify miR-137 as a potential regulator of FBI-1. Our results showed that expression of miR-137 was downregulated, while FBI-1 was upregulated in clinical HCC specimens, compared with paired non-tumor specimens. Overexpression of miR-137 via adenoviral vector inhibited the proliferation and anchorage-independent growth of HCC cells, HepG2 and MHCC-97H. Our data also showed that miR-137 repressed endogenous expression level of FBI-1, as well as Notch-1 and Survivin. MiR-137 also inhibited in vitro invasion and migration of HCC cells and attenuated their epithelial-mesenchymal transition (EMT) process. Moreover, miR-137 suppressed the growth rate of HepG2 cells in nude mice model. Overexpression of miR-137 via its adenoviral vector enhanced the sensitivity of HepG2 cells to anti-tumor drugs and attenuated the MDR process of a resistance cell line HepG2/adriamycin (ADR). Thus, FBI-1 downregulation mediated by miR-137 overexpression may be a potential strategy for HCC treatment.
