Through in vitro experiment, Liu et al. showed co-cultured cell lines SGC-7901 and MKN45 with human recombinant IL-23A and H. pylori lysate induced IL-17A/IL-17RA/NF-κB activation [108], while Xu et al. demonstrated IL-23 promoting tumor cell migration via STAT3 in BGC-823 GC cell line [109]. Here, IL23A is linked to gastric cancer.
