Figure 3. Telomerase reactivation maintains telomere length and allows tumor cells to proliferate.
(A) Strong telomere dysfunction-induced p53BP1 foci were presented in G3/4 mTert−/− cells (panel b), but not in G4 LSL-Tert cells (panel c). (B) Quantification of p53BP1 positive prostate tumor cells. Error bars represent s.d. for a representative experiment performed in triplicate. (C–E) Telomere dysfunction induced apoptosis and blockage of proliferation. Quantification of TUNEL positive (C), Caspase-3 activation positive (D), and Ki67 positive prostate tumor cells (E). Error bars represent s.d. for a representative experiment performed in triplicate. See also Figure S3.
