Figure 4. E27 affects neither HCV co-receptor localization nor expression levels.
(a) DMSO and E27 (1 μM) were added to Huh7 cells and allowed to incubate for 24 h. CLDN1, OCLND, CD81 and SR-BI were stained with corresponding antibodies (green), and nuclei (blue) were stained with DAPI. (b) Huh7 cells were treated with 0, 0.1, 1 or 5 μM of E27, and the expression levels of CLDN1, OCLND, CD81 and SR-BI were analyzed by Western blotting. The expression of β-actin was also analyzed as a loading control.
