FIG. 4.
Concordance of differential gene expression between DNA array and quantitative real time-PCR Analysis. Fold change values for negative controls and differentially expressed genes were generated by comparing untreated to CB2-treated samples. In all cases, 16S ribosomal subunit was used as the internal control for real-time PCR (RT-PCR). Correlation coefficient = 0.90; trend line was generated with linear regression analysis.
