Fig. 8. Inhibition of exosome secretion with inhibitor, GW4869, delayed cyst growth in Pkd1RC/RC mice.
a Images of kidneys (top panel) and axial MRI images (bottom panel) from Pkd1RC/RC mice treated with or without GW4869. Scale bars, 5 mm. b Histological examination of kidneys from Pkd1RC/RC mice treated with or without GW4869. Scale bars, 1 mm. c MRI images from Pkd1RC/RC mice treated with or without GW4869. Scale bars, 1 mm. d Treatment with GW4869 deceased cystic index in kidneys from Pkd1RC/RC mice (n = 5) compared to that in kidneys from control mice treated with DMSO (n = 5). Treatment with GW4869 decreased KW/BW ratios (e) and BUN levels (f) in Pkd1RC/RC mice compared to those in kidneys from control mice treated with DMSO. g Total kidney volume (TKV) was calculated by MRI scan in each group. h Histological examination of kidneys from wild-type mice treated with GW4869 (n = 5). Scale bars, 1 mm. Treatment with GW4869 did not affect KW/BW ratios (i) and BUN levels (j) in GW4869-treated wild-type mice compared to the controls. All statistical data are represented as mean ± SEM, and p values are calculated by unpaired Student’s t-test.
