چکیده انگلیسی
Infection of Hepatitis B virus (HBV) in hepatocytes has been known to be controlled by multiple cellular factors, while the relationship of the infection and liver microRNAs remains obscure. In this study, a miRNA database, containing 168 unique mature miRNA members from primary hepatocytes of a primate-like animal, northern treeshrew (Tupaia belangeri) that is the only species susceptible for HBV infection other than human and chimpanzee, was established. The relative level of a liver predominant microRNA, miR-122, was markedly increased upon HBV infection of the primary tupaia hepatocyte (PTH). However, introducing neither miR-122 nor its antagonist anti-miR-122 into PTHs, or, HepG2-NTCP that is HepG2 cells with the newly identified receptor sodium taurocholate cotransporting polypeptide (NTCP) did not alter the viral infection on these cells. These data suggest that de novo HBV infection of cultured hepatocytes does not depend on the expression level of intracellular miR-122 of the target cells.
