Article Title: Increased QPCT gene expression by the hepatitis B virus promotes HBV replication
doi: 10.1371/journal.pone.0312773
Figure Lengend Snippet: (B and C) HepG2.2.15 cells and HepG2 cells at the same cellular concentration (1 × 10 6 cells) were cultured for 48 h. Supernatants and cells were harvested. The protein and mRNA expression levels of QPCT were detected by Western blot and RT‒PCR, respectively. (E and F) After the gradient transfection of pBlue-HBV 1.3-fold plasmids into HepG2 cells, the cells were cultured for 48 h. Supernatants and cells were harvested. The protein and mRNA expression levels of QPCT were detected by Western blot and RT‒PCR, respectively, with the mRNA expression level of GAPDH as a reference. (H and I) Huh7 cells were analyzed in the same way as HepG2 cells. (A, D, and G) ELISA results for HBeAg and HBsAg concentrations in cell supernatants demonstrated successful infection.
Article Snippet: The ELISA kits for hepatitis B surface antigen (HBsAg) and e-antigen (HBeAg) detection were purchased from Shanghai Kehua Biological Engineering Co., Ltd., and the ELISA kit for QPCT detection was purchased from SAB (Signalway Antibody LLC).
