(a,b) Colony-forming assay of XPV cells (a) and
XPV + Polη cells (b) irradiated with UV alone (black) or a combination
of UV and 20 μM ML323 (red). The data represent the mean ± s.d. of three
independent experiments. (c,d) Cytotoxicity assay of PD20 cells
(c) and PD20 + D2 cells (d) treated with cisplatin alone
(black), ML323 (blue) or a combination of cisplatin with ML323 at a ratio of 1:4 (red).
The data represent the mean ± s.d. of three independent experiments.
(e) Colony-forming assay of PD20 cells irradiated with UV alone (black) or
a combination of UV and 20 μM ML323 (red). The data represent the mean ±
s.d. of three independent experiments. (f) Comparison of FANCD2 foci
formation in U2OS cells treated with 30 μM ML323, 5 μM cisplatin or a
combination of 30 μM ML323 and 5 μM cisplatin. Scale bars, 10 μm.
DAPI, 4′,6-diamidino-2-phenylindole.
