eIF3B CLIP-sequencing in prostate cancer. eIF3B CLIP-sequencing in prostate cancer

The role of eIF3B in advanced therapy resistant lethal stages of prostate cancer remains unknown. To gain insight into how eIF3B regulates the translation of specific mRNAs we performed Genome-wide eIF3B enhanced cross-linking immunoprecipitation sequencing (eCLIP-seq). this analysis showed specialized binding to a UC-rich motif present in subsets of 5’-UTRs. Indeed, translation of the androgen receptor (AR) and major histocompatibility complex I (MHC-I) through this motif are sensitive to eIF3B amount. These results suggest that eIF3B by regulating specific mRNA translation may play key role in the pathogenesis of lethal prostate cancer.
