Examination of the 10-gene signature molecular model's gene functions in existing literature indicated that high expression of SLC2A3 [29], MMP11 [30], SCARA3 [31], GPC1 [32], OLFM2 [33], L1CAM [34], CRABP2 [35] is linked to adverse cancer progression, and elevated expression of PHGR1 [36], TFF1 [37], and CLCA1 [38] is associated with a good prognosis of tumors. This evidence concerns the gene TFF1 and cancer.
