IL-1 beta→Tumor Necrosis Factor-alpha→Tumor Necrosis Factor-alpha→poly-ADP-ribose

• 19081643(IL-1+beta): Tumor necrosis factor-alpha, interleukin-1beta and nitric oxide induce calcium transients in distinct populations of cells cultured from the rat area postrema.

  Evidently , the AP can act as a sensor for circulating TNF-alpha and IL-1beta , or for locally produced cytokines and NO during infection and inflammation.

• 10446825(Tumor Necrosis Factor-alpha): Tumor necrosis factor-alpha and interleukin-1beta synergistically depress human myocardial function.

  Inhibition of myocardial sphingosine or NO release abolished the myocardial depressive effects of either TNF-alpha or IL-1beta.

• 1280112(Tumor Necrosis Factor-alpha): Induction of nitric oxide synthase in L929 cells by tumour-necrosis factor alpha is prevented by inhibitors of poly(ADP-ribose) polymerase.

  Induction of NO synthase by TNF-alpha was prevented by inhibitors of poly (ADP-ribose) polymerase , namely nicotinamide , 3-methoxybenzamide and 3-aminobenzamide.

• 9521710(poly-ADP-ribose): Inhibitor and NAD+ binding to poly(ADP-ribose) polymerase as derived from crystal structures and homology modeling.

  Inhibitors of poly (ADP-ribose) polymerase (PARP , EC 2.4.2.30) are of clinical interest because they have potential for improving radiation therapy and chemotherapy of cancer.
