CP690550 inhibits cell viability of AsPC-1 and PANC-1 cells.

<p>(A), AsPC-1 cells were seeded in 96 well plates at 4×10⁴ cells per well and treated with CP690550 (0–15 µM) for 72 h. Cell viability was measured by XTT assay. Data represent mean ± SD. * = significantly different from control, P<0.05. (B), PANC-1 cells were seeded in 96 well plates at 4×10⁴ cells per well and treated with CP690550 (0–15 µM) for 72 h. Cell viability was measured by XTT assay. Data represent mean ± SD. * = significantly different from control, P<0.05.
