In comparison, > 750-fold higher IL-6 was measured in sera from IRIS291 tumor-bearing mice injected with scrambled peptide (0.79 ± 0.09 ng/ml, Fig. 3c, upper left black) or IRIS293 tumor-bearing mice injected with scrambled peptide (0.76 ± 0.05 ng/ml, Fig. 3c, upper right black). This evidence concerns the gene IL6 and neoplasm.
