Expression levels are ratios of R(+)-WIN 55,212-2- or Δ9-THC-treated versus control samples. Each mRNA sample group was hybridized to three different arrays, and fold-change values are average of the triplicate measurements. Matches of clone sequences from cDNA arrays were based on the closest calculated expect value (E).
