Additionally, the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)-RelA (p65 subunit) and specificity protein (Sp)-1 bind to the hnRNPD and hnRNPK promoters, respectively, as shown by chromatin immunoprecipitation (ChIP) and electrophoresis mobility shift assays (EMSA) in oral and breast cancer cells [55,56]. Here, HNRNPK is linked to breast cancer.
