NFKB1 and ulcerative colitis: Besides, many signaling pathways contribute to the development of ulcerative colitis, such as the NF‐κB signaling pathway (Lin et al. 2022), the Bcl‐2/Bax signaling pathway (Fu et al. 2022), the c‐Jun N‐terminal kinase (JNK) signaling pathway (Wang, Bai, et al. 2022), and so on.
