IGF2BP1 and neoplasm: Although around a quarter of uninvolved lymph nodes (5/20 cases) and normal gastric mucosa (7/31 cases) were classified as high IGF2BP1 protein abundances, the staining was confined mainly to a few scattered lymphocytes or potentially nonspecific staining within gastric glands (supplemental Fig. S2B), suggesting that IGF2BP1 tends to be expressed in epithelial-derived tumor cells in EAC.
