ABSTRACT
Objective To study the pathogenesis mechanism of hepatitis C vires (HCV) core protein (CORE), the subcellular localization of different truncated genotype 1b HCV CORE was observed. Methods HepG2 cells were transiently transfected with the enhanced green fluorescence protein (EGFP-CORE) recombinant plasmids, which expresses EGFP and COREs from three different genotype lb HCV strains and different truncated COREs from one HCV strain. The localizations of different truncated COREs was analyzed by the laser scanning confocal microscope and fluorescence microscope. Results N terminal 1-172 an of different HCV strains of genotype 1b expressed mainly in cytoplasm. Among the different truncated COREs, the longer of the CORE containing N terminal, the more expressed in cytoplasm. The N terminal 1-58 aa mainly expressed in nucleus. CORE of 59-126 aa and 127-172 aa expressed both in cytoplasm and nucleus. Conclusion The different localizations of different truncated COREs might have some relationships with their functions in pathogenesis.
