Post-operative changes in plasma protein and PBMC mRNA levels of cytokines.

Results of initial screening of plasma for cytokine/chemokine/growth factor levels and comparison to PBMC gene expression (microarray) database are displayed. Mean ratios of preoperative expression over postoperative expression are presented along with their corresponding standard deviations and ranges. A positive value indicates higher levels preoperatively. All values are expressed using a log2 scale. P-values were obtained using paired t-tests. The targets are ranked based on the ratios calculated for the Luminex data. The bolded cells indicate the 5 cytokines selected for further study.
