In order to find microRNA associated with HBV infection and to explore the mechanism of the infection, first of all, we found in our preliminary study that in HepG2 cells transfected with HBV expression plasmid, miR-122 expression was up-regulated, suggesting that miR-122 was related to the HBV infection. On this basis, in the present study, miR-122 and pCH9-HBV1.1 plasmid were cotransfected into HepG2 cells. Southern blot detection result showed that miR-122 can inhibit HBV replication. Using MiRanda computer software, HBx was predicted to be the target sequence of miR-122; Luciferase reporter gene system and Western blot detection of HBx protein expression changes were further used to verify the HBx expression regulated by miR-122. And finally, it can be speculated that miR-122 may affected HBV replication by regulating the expression of HBx.

In order to investigate the molecular mechanisms of SARI expression regulation in chronic myeloid leukemia (CML), 46 patients with CML and 40 healthy volunteers were recruited in this study. SARI expression in the peripheral blood mononuclear cells (PBMNC) of CML patients and healthy volunteers was assayed by using real-time quantitative PCR. K562 cells were in vitro incubated with the BCR-ABL inhibitor STI571 (imatinib) at 37°C and 5% CO2 for 24 hours, then SARI expression was detected by using real-time quantitative PCR. All experiments were repeated three times. The results showed that as compared with healthy volunteers, the expression of SARI mRNA in PBMNC of CML patients presented a lower level (p < 0.001). After exposure of K562 cells to STI571 (2.5 µmol/L) for 24 hours, the SARI expression was higher than that in K562 cells treated without STI571 (p < 0.001). It is concluded that the suppression of SARI expression is involved in CML pathogenesis, and BCR-ABL mediates the down-regulation of SARI mRNA expression in K562 cells. These findings suggest a new orientation for gene therapy in CML patients.
