Fig. 2. Sample data : cDNAs from untreated Human THP-1 cells (monocytic leukemia) (wells in column 1, 3, 5, 7, 9, 11) and the same cells treated with PMA (wells in column 2, 4, 6, 8, 10, 12) were profiled with a Map kinase pathway AmpArray™: wells B11-B12 indicated the change of splicing form; wells E11-E12 and wells F5-F6 represented down-regulated and up-regulated expression, respectively.
