• 18488438(IL-6): Systemic inflammation after inspiratory loading in chronic obstructive pulmonary disease.

  OBJECTIVE : Patients with chronic obstructive pulmonary disease (COPD) present systemic inflammation.

• 12853070(NAD): Systemic poly(ADP-ribose) polymerase-1 activation, chronic inflammation, and oxidative stress in COPD patients.

  Oxidative stress and systemic inflammation in chronic obstructive pulmonary disease (COPD) strongly suggest a role for the nuclear enzyme poly (ADP-ribose) polymerase-1 (PARP-1 , E.C. 2.4.2.30) in the disease pathophysiology.

• 17766683(Histones): Differential contribution of poly(ADP-ribose)polymerase-1 and -2 (PARP-1 and -2) to the poly(ADP-ribosyl)ation reaction in rat primary spermatocytes.

  We propose that a different propensity of PARP-1 and PARP-2 to undergo automodification and/or catalyze etheromodification , both in terms of number of enzyme molecules being involved and amount of bound poly (ADP-ribose) , may underlie distinct roles in the regulation of spermatocyte functions.

• 8835300(poly-ADP-ribose): Inhibition of the induction of collagenase by interleukin-1 beta in cultured rabbit synovial fibroblasts after treatment with the poly(ADP-ribose)-polymerase inhibitor 3-aminobenzamide.

  3-Aminobenzamide is an inhibitor of poly - (ADP-ribosyl) ation.
