In line with this finding, NF-kB target genes like IL6, IL8, CXCL1 and TNFalpha were induced in three different cell lines derived from embryonic kidney and breast cancer, albeit with different induction patterns (Figure 4C–4E), suggesting that the modulation of NF-kB by the miR-15/16 miRNA family can occur in different tissues. Here, IL6 is linked to breast carcinoma.
