To explore this, we generated a signature gene set of upregulated genes from our dual CIC and ERF deficient PNT2 cells (ERF KD +CIC KO) and projected the Cancer Genome Atlas PCa (TCGA-PRAD) dataset onto the transcriptional space of these signature gene sets using the ssGSEA module (Version 10.0.9) on GenePattern (Reich et al., 2006). Here, ERF is linked to posterior cortical atrophy.
