To gain insight into the biological functions of CARHSP1 in PCa, we employed gene set enrichment analysis (GSEA) based on the TCGA PCa cohort and hallmark signatures, and found that the gene set of “Hallmark_G2m Checkpoint” was significantly positively associated with CARHSP1 mRNA levels (Fig. S1B). The gene discussed is CARHSP1; the disease is posterior cortical atrophy.
