Co-expression network analysis of datasets from the GEO database has identified four key genes involved in gastric cancer progression including ITGAX, chemokine (C-C motif) ligand 14 (CCL14), alcohol dehydrogenase iron-containing protein 1 (ADHFE1), and Homeobox B13 (HOXB13) (Rezaei et al., 2022). Here, CCL14 is linked to gastric cancer.
