The malignant neoplasias of prostate and gastric cancers also share many genes, one of the most important of which is mt2a. The mt2a gene is a member of the metallothionein family of genes, which code proteins that have a substantial role in the hemostatic control of metals in cells and detoxification of heavy metals influences apoptotic and autophagy pathways89. This evidence concerns the gene MT2A and gastric cancer.
