Figure 1. Palbociclib inhibits growth of NSCLC cell lines.

NSCLC cell lines were treated with increasing doses of palbociclib for 7 days. The Cell Titer-Blue® Cell Viability Assay was used to quantitate cell metabolic activity as a surrogate marker for viability. Viability was expressed as a percent of untreated cells. Data represent the mean ± SEM of at least three independent experiments, each performed in triplicate.
