NO–HIF-1 input in tumor progression and therapeutic achievement. NO together with HIF-1 influences the main processes involved in the conversion of less-aggressive toward high-aggressive phenotype. HIF-1 regulates the expression of genes responsible for stem phenotype establishment, remodeling of the extracellular matrix (ECM), angiogenesis, and NO synthesis, while NO influences HIF-1 stability.
