Figure 1From: Cellular apoptosis induced by replication of hepatitis B virus: possible link between viral genotype and clinical outcomeFlow cytometry analysis of apoptotic effect by HBV genome A, B, and C. HepG2 cells were transiently transfected with HBV genome A, B, and C and incubated for 24 h (panel C, D, E, respectively) and 48 h (panel F, G, H, respectively) before collected and applied to FACS assay. Cells transfected with empty vector pcDNA3.1 (panel A) and cells treated with cisplatin (panel B) were used as (-) and (+) controls. Cells were labeled by annexin-V-Fitc (FL1-H) and propidium iodide (FL2-H). In each panel, the lower right square (LR) indicates the number of apoptotic cells' portion. Data: LR: A:0.62%, B: 17.32%, C: 2.53%, D: 2.69%, E:1.61%; F: 9.18%, G: 16.13%, H: 6.86%Back to article page
