IL1B and neoplasm: While there were no differences in either TP, IL-1β or IL-6 expression between the primary and secondary tumor specimens (Fig.5 H-J), it is noteworthy that the basal expression of TP was high relative to constitutive gene EF2 in tumor tissue (mean TP/EF2 = 2.202), which is comparable with the TP/EF2 levels obtained in our TP-overexpressing xenografts (mean TP/EF2 = 1.027, see Fig. 5E).
