To extrapolate relevance to human CRC from these mouse models, we examined expression data from human samples from The Cancer Genome Atlas (TCGA) [35] by querying for expression of Let-7 target mRNAs, with a focus on targets that exhibited significant up-regulation in either Vil-Lin28bMed or Lin28bLo/Let7IEC-KO mouse models (namely, ARID3A, PLAGL2, HMGA1, HMGA2, MYCN, IGF2BP1, IGF2BP2, and E2F5). Here, IGF2BP1 is linked to colorectal carcinoma.
