The IGF2 mRNA binding protein 1 (IGF2BP1) promotes tumor progression in a multitude of solid tumors and its expression is associated with adverse prognosis. The main role proposed for IGF2BP1 in cancer cells is the stabilization of mRNAs encoding pro-oncogenic factors. Several binding studies, however, revealed a plethora of putative IGF2BP1-RNA targets. Thus, at present the main, conserved target RNAs and pathways controlled by IGF2BP1 in cancer remain elusive. In this study, we present a set of genes showing a conserved pattern of deregulation in dependence of IGF2BP1 expression in cancer-derived cell lines. By incorporating publicly available data sets, we further compiled a set of RNAs probably stabilized by IGF2BP1 in cancer and characterized them. Functional enrichment analyses revealed conserved pathways influenced by IGF2BP1 in cancer. Overall design: small RNA-Seq of different solid tumor-derived cells.
