MAOA and prostate neoplasm: Jessica A. Lapierre et al. [82] reported that the deletion of MAOA delayed prostate tumor development in the MAOA/Pten DKO mouse model of prostate adenocarcinoma, and high lever markers of immune stimulation (such as CD8+ cytotoxic T cells, granzyme B, and IFN-γ) have been detected in this DKO mice while decreasing expression of markers of immune suppression (such as FoxP3, CD11b, HIF-1-alpha, and arginase 1) were found.
