Our results showed that ROMO1 expression was strongly correlated with immunity to PCa and was found to be negatively correlated with B cells, CD8 + T cells, macrophages, neutrophils, dendritic cells and positively correlated with CD4 + T cells; PLK1 and KLF4A expression was positively correlated with B cells, CD8 + T cells, macrophages, neutrophils, dendritic cells (Fig. 10 A-C). The gene discussed is ROMO1; the disease is posterior cortical atrophy.
