Figure 4. Neratinib reduced the levels of telomerase activity in AU565 cells. (A) Cells were stimulated with Neratinib (1, 2.5, 5 μM) for 7 days. The telomerase activity was assayed; (B) Cells were stimulated with Neratinib (1, 2.5, 5 μM) for 14 days. The telomerase activity was assayed (^, ^^, ^^^, P<0.05, 0.01, 0.005 vs. vehicle group).
