Figure 1
Clonogenic survival of Panc-1 cells treated with either irradiation and/or oridonin (ORI) and ponicidin (PON) as indicated. (A) survival curves and (B) radiosensitivity to different dosages with measured and theoretical control curve, according to Steel and Peckham for Panc-1 cells. Results are presented as mean values +/− standard deviation. At least three independent experiments were performed.
Figure 2
Cell cycle assay of Panc-1 cells treated with irradiation and/or (A) oridonin (ORI) and (B) ponicidin (PON) as indicated. Results are presented as mean values +/− standard deviation. *P<0.05, **P<0.005, asterisk referring to the amount of cells in G2/M-phase. At least two independent experiments were performed.
Figure 3
γH2AX-intensity of Panc-1 and MIA PaCa-2 cells treated with irradiation and/or (A) oridonin (ORI) and (B) ponicidin (PON) as indicated. Results are presented as mean values +/− standard deviation. *P<0.05, **P<0.005, ***P<0.001, n.s.=not significant. At least three independent experiments were performed.
Figure 4
Western Blots of Panc-1 and MIA PaCa-2 cells treated with either (A) oridonin (ORI) and (B) ponicidin (PON) as indicated. One representative Western Blot is shown. At least two independent experiments were performed. NHEJ = non-homologous end-joining.
