Fig. 4From: IL-6 is associated to IGF-1Ec upregulation and Ec peptide secretion, from prostate tumorsImmunohistochemical detection of IL-6 and PEc in prostate tumors in SCID mice. IL-6 and PEc present proportional expression levels that increase as tumors progress. IL-6 is mainly expressed from cancer cells rather than infiltrating cells of the IR. W1, w2, w4 stands for week 1, 2, 4 after tumor detection by palpitation. (n = 3 mice per case were used)Back to article page
