Figure 6. Effect of C188-9 or PL treatment on levels of pSTAT3 levels in PBMC.
Levels of pSTAT3 and total STAT3 were determined using Luminex beads in protein extracts of PBMC isolated from whole blood of tumor-bearing mice after 3 weeks of treatment with vehicle, C188-9, or PL. Level of pSTAT3 were normalized to total STAT3. The mean ± SD is shown; an asterisk (*) indicates a reduction in pSTAT3 level compared to vehicle (p=0.039).
