RELA and cancer: As IL-1β has also been linked to the expression of other cancer-associated cytokines [38], we tested the impact of miR-7-5p or si-RelA on expression of IL-6 and IL-8, and found that both miR-7-5p and si-RelA reduced the levels of secreted and intracellular IL-6 and IL-8 (Figure 6B and Supplementary Table S7).
