TFF3 and cancer: STModule identifies three tissue modules related to cancer cells from sample P1.2, among which module I discriminates between cancer cells (SPINK1, FMOD, AGR2) and PIN (NPY, ACPP, DBI), module II reveals shared features of cancer and PIN (SPON2, TFF3), and module III aligns with the center of the cancer region as annotated in the original study [5] (Fig. 4f, h).
