ECP-induced fold increase in expression of genes affecting monocyte adhesion, migration, and signaling.
Impact of treatment on gene expression is displayed as an induced expression ratio (ratio of ECP Day 1 to pre-ECP expression for the relevant gene). RNA was isolated from 3 CTCL patients and 3 GVHD patients and 6 normal subjects at the relevant time points.
