Fig. 4From: Hepatitis B virus whole-X and X protein play distinct roles in HBV-related hepatocellular carcinoma progressionSubcellular localization of HBwx and HBx in transfected cells. a EGFP fused HBwx or HBx protein in HL7702 cells was observed respectively by fluorescent microscopy; b SMMC-7721 cells transiently transfected with pCMV-Tag2A-wX or pCMV-Tag2A-X and control were observed by cell immunofluorescence staining. Both results showed that HBwx was mainly expressed in the nucleus, whereas HBx in the cytoplasmBack to article page
