FNDC1 and colorectal cancer: Patients with stomach, breast, and prostate malignancies have frequently been found to have FNDC1 upregulation in clinical samples,[3,17,31] and FNDC3B is increased in liver, lung, and colorectal cancers.[5,32,33] Our expression analyses revealed that the mRNA levels of FNDC1 and FNDC3B were significantly higher in most malignancies than in normal tissues, which is consistent with previous studies.
