Six mRNAs were selected that exhibited an enrichment in the Ago complexes from PCa cells and were therefore potentially downregulated in cell lines and tumors: Etoposide induced 2.4 mRNA (EI24, alias p53-induced gene 8 protein), S100 calcium binding protein A16 (S100A16), Nemo-like kinase (NLK), RAS oncogene family member 1B (RAB1B), death effector domain-containing protein (DEDD), and cullin 5 (CUL5). The gene discussed is FBXW7; the disease is posterior cortical atrophy.
