Figure 9. In vivo assessment of ERp57 inhibition.

(A) 4- to 8-week-old NOD-FRG mice were engrafted with primary human hepatocytes (PHH). After approximately 2–3 months, the animals displaying human serum albumin (HSA) levels >15 mg/ml were randomly split into four different groups (N = 3 to N = 5 animals, see Table in the inset) that were infected with hepatitis B virus (HBV) (108 genome equivalent (GE)/mouse), using the displayed nitazoxanide (NTZ) treatment schedule. (B) At different time points post-infection, blood samples (50 µl) were collected and the viremia in sera was monitored by quantitative PCR (qPCR) (GE/ml of serum). The graphs show the results of viremia (means ± SD) of HBV. See results of individual mice in Figure 9—figure supplement 1.

(A) Nitazoxanide (NTZ) at 30 µg/ml was added to the cell supernatant 2 hr before infection (2h-) vs at the onset of infection (0 hr), at 4 hr (4h+) or at 16 hr (16h+) post-infection. Dimethyl sulfoxide (DMSO) was used as the control vehicle. At 7 days post-infection, hepatitis delta virus (HDV) RNAs were extracted from cells and quantified by quantitative reverse transcription PCR (RTqPCR). The results are expressed after normalization with glyceraldehyde 3-phosphate dehydrogenase (GAPDH) RNAs as means ± SD (N = 4) per ml of cell lysates containing 106 cells. (B–E) Study of NTZ effect in hepatitis B virus (HBV) in vivo. 4- to 8-week-old NOD-FRG mice were engrafted with primary human hepatocytes (PHH). After approximately 2–3 months, the animals displaying human serum albumin (HSA) levels >15 mg/ml were split into four groups that were infected with HBV (108 genome equivalent (GE)/mouse) with or without NTZ. See schedule in Figure 9A. At different time points post-infection, blood samples (50 µl) were collected and the viremia in sera was monitored by quantitative PCR (qPCR) on the HBV genome (GE/ml of serum). The graphs show the results of viremia for individual mice within each group. (B) Group #1: mice were infected and inoculated with DMSO, (C) Group #2: mice were infected and inoculated with NTZ (100 mg/kg), (D) Group #3: mice were only inoculated with NTZ (100 mg/kg), and (E) Group #4: mice were only inoculated with DMSO (used as the control vehicle of NTZ).
