Figure 1. Study of the sensitivity of four human HNSCC cell lines to ABT-737.

Figure 1

(A) Correlation between the sensitivity to ABT-737 (IC50) and the radiosensitivity of cell lines (SF2). (B) Expression of Bcl-2 family proteins of the four cell lines and the CSC sub-population (SP+/CD44high/ALDHhigh) was performed by Western blotting experiments. The correlation between sensitivity to ABT-737 (IC50) and (C) Bak expression, or (D) Bcl-XL expression were normalized to the expression of α-tubulin.
