Gene expression analysis of choroid plexus tumors. Homo sapiens

Gene expression was assessed in a cohort of 40 choroid plexus tumors isolated from fresh-frozen tissue. We investigated unique expression patterns among tumor subgroups and refined the classification of choroid plexus tumors according to gene expression intensities. Overall design: Forty choroid plexus tumors (16 choroid plexus carcinomas, 16 choroid plexus papillomas and 8 atypical choroid plexus papillomas) were analyzed. No replicates were used.
