Role of nitric oxide in tumour progression with special reference to a murine breast cancer model

Abstract excerpt

Nitric oxide (NO) is a potent bioactive molecule produced in the presence of NO synthase (NOS) enzymes, which mediates numerous physiological functions under constitutive conditions. Sustained overproduction of NO (and NO-reaction products), typically under inductive conditions, can lead to cell cycle arrest and cellular apoptosis. Furthermore, carcinogenesis may result from mutational events following...
