NFKB1 and gastric cancer: Many of the miRNAs previously studied that have been targeted with NF-κB signalling, such as miR-21, have been linked to both immune response and inflammation (Mima et al. 2016; Schetter et al. 2009), have been shown to be mediated by NF-κB in response to oxidative stress (Wei et al. 2014), or have been associated with specific cancers such as gastric cancer (Sha et al. 2014).
