p73β inhibits transcriptional activities of enhancer I and X promoter in hepatitis B virus more efficiently than p73α

Figure 3 Northern blotting analysis of HBV viral transcripts, including pregenomic/precore RNA and preS/S RNA. HepG2 cells were transiently transfected with p3.8IIXm, and also with the expression plasmids. Lane 1 represents pcDNA3, lane 2, p53, lane 3, p73β, lane 4, pHBX and lane 5, p73α respecitively. Total cellular RNA were extacted and α-³²p-dCTP labeled 3.2 kb HBV DNA or G3PDH used as probe.
