To evaluate this, we conducted a well-s H2AX foci with time rc car, C225 alone, only 888 or a combination of ABT ABT 888 and C225. As shown in Fig. 6, relative to the active ingredient Trise of the vehicle, the second C225 Erh Cytotoxicity hte t in head and neck cancer cells involves the intrinsic pathway of apoptosis. % Of apoptotic cells after treatment with cetuximab combined and ABT 888 in Fadu and unified messaging SCC6 cells.

Interestingly, the combination of C225PARPi was statistically different from one agent, ABT 888 and C225 increased Hte apoptosis in Fadu and unified messaging SCC6 cells as evidenced by cleavage of caspase 3.
