A Review on Anticancer Potential of Nitric Oxide

Nitrous oxide (NO) is a free radical gas which performs various physiological and pathological processes in body. NO is produced by different enzymatic pathways and plays role in homeostasis. Over past years, NO has emerged as a molecule of interest in many ailments including cancer. But its role in cancer is still controversy. It can display dose-dependant anticancer therapy on one hand and induce procancer properties on the other hand. But as compared to conventional treatments, NO proved better tumor cell resistance. This review mentions dichotomous nature of NO that may encourage future research assessing the role of NO in cancer prevention and treatment either as a single agent or in combination with other antineoplastic compounds
