We further explored CALD1 co-expression with regulators of cancer hallmarks, actin-related processes, and relevant signaling pathways based on curated sets of positive and negative regulators separately (Gene Ontology: Biological Processes) on mRNA level in the largest single PCa patient data set (PCa subset of the PanCancer TCGA data set) by producing CALD1 co-expression heatmaps. This evidence concerns the gene CALD1 and posterior cortical atrophy.
