Breast DCIS cells overexpress proinflammatory markers. Representative images of immunohistochemistry targeting IL-6 protein in normal breast tissue (a), and breast DCIS (b) (N = 61). c and d Hematoxylin staining of serial sections from tissue shown in panel A and B. All images are 20X magnification. Scale bar equals 100 μm. e Evaluation of IL-6 gene expression in DCIS cells via qRT-PCR; the isogenic MCF10.DCIS cells and the non-isogenic SUM102 cell line were analyzed against the non-transformed MCF10A cell line (N = 3). f Secretion of IL-6 protein from DCIS cell lines and non-transformed MCF10A cells as determined by ELISA. *P < 0.05, Student’s t-test; mean ± SD
