Fig 6. NOXA or fenretinide in combination with ABT-263 enhances cell death in HPV-positive UMSCC47 and UMSCC104 cells.

Fig 6

(A) Top: UMSCC47 cells were treated with Ad-NOXA (N), fenretinide (F; 10 μM) and/or ABT-263 (A; 1 μM) for 16 h and equal amounts of the total extracts were analyzed by Western blots with the indicated antibodies. Middle: Cells were treated as above for 24 h and the amounts of apoptosis were determined by Annexin V-PI staining followed by FACS analyses (N = 3). Values represent the means ± S.D. (B) UMSCC104 cells were treated and analyzed as above. Values represent the means ± S.D. for four independent experiments.
