Cartoon diagram showing how homocysteine and H2S balance can be targeted for cancer treatment. Targeting the transsulfuration and remethylation pathway in cancer cells will build up highly toxic homocysteine inside the cells. Consequently, cancer progression will be inhibited via apoptosis, poor angiogenesis, protein oxidation, and oxidative and ER stress.
