Shou et al. [36], Nagano et al. [33], and Schulz et al. [37] demonstrated that a significant proportion of genes whose downregulation is associated with PCa tumorigenesis were IFN-inducible genes, including MX1. However, MX1 has been mostly studied for its antiviral properties [14,15,16]. The gene discussed is MX1; the disease is posterior cortical atrophy.
