Time course of MEK inhibition

This study used microarray expression analysis to identify global changes in transcript alteration in response to MEK inhibition. Genes under ERK control were identified in a representative V600E BRAF cell line as a function of time following exposure to a small molecule inhibitor of MEK. Keywords: Time course SkMel-28 cells growing in culture were treated with the MEK inhibitor PD0325901 for 2, 8, or 24 hours. Changes in RNA compared to reference (time =0) were measured using microarray analysis.
