Western-blot images and immunofluorescence staining all showed that (Figure 2), compared with the control group, the groups receiving CF, CF-20, CF-30, and CF-40 all showed the decreased expression of AQP1, AQP2, AQP3, and AQP4 significantly (P < 0.05 and P < 0.01), with the strongest effects seen in response to CF-20, CF-30, and CF-40. Here, AQP4 is linked to cystic fibrosis.
