EIF3 is the largest multi-protein complex, and several studies have revealed the oncogenic roles of its subunits in many human cancers. However, the roles of EIF3D in the development and progression of PCa remain uncovered. In the present study, the expression of EIF3D in prostate cancer and paracarcinoma tissues, as well as PCa cell lines, was examined. In PCa tissues, the expression of EIF3D was up-regulated compared to that in paracarcinoma tissues. In order to investigate whether EIF3D could serve as potential therapeutic target for prostate cancer, EIF3D was knocked down to verify its functional role in prostate cancer cells. After EIF3D knockdown in PC-3 and DU145 cells, cell proliferation, invasion and colony formation were significantly inhibited; meanwhile, cell cycle analysis revealed cell cycle arrest at G2/M phase. EIF3D is associated with PCa, and silencing EIF3D will result in decreased proliferation, and migration, as well as G2/M arrest in DU145 and PC-3 cells. These results suggest that EIF3D plays an oncogenic role in PCa development and progression.

Docetaxel has been the standard first-line therapy in metastatic castration resistant prostate cancer. The survival benefit is, however, limited by either primary or acquired resistance. In this study, Du145 prostate cancer cells were converted to docetaxel-resistant cells Du145-R and Du145-RB by in vitro culturing. Next generation RNAseq was employed to analyze these cell lines. Forty-two genes were identified to have acquired mutations after the resistance development, of which thirty-four were found to have mutations in published sequencing studies using prostate cancer samples from patients. Fourteen novel and 2 previously known fusion genes were inferred from the RNA-seq data, and 13 of these were validated by RT-PCR and/or re-sequencing. Four in-frame fusion transcripts could be transcribed into fusion proteins in stably transfected HEK293 cells, including MYH9-EIF3D and LDLR-RPL31P11, which were specific identified or up-regulated in the docetaxel resistant DU145 cells. A panel of 615 gene transcripts was identified to have significantly changed expression profile in the docetaxel resistant cells. These transcriptional changes have potential for further study as predictive biomarkers and as targets of docetaxel treatment.
