IL-6→Matrix Metalloproteinase 1→Tumor Necrosis Factor-alpha→poly-ADP-ribose

• 18257779(IL-6): Elevation of matrix metalloproteinases and interleukin-6 in the culprit coronary artery of myocardial infarction.

  MATERIALS AND METHODS : One hundred and twenty-two patients with AMI were included.

• 12655159(Matrix Metalloproteinase 1): Increased serum matrix metalloproteinase-1 concentration predicts advanced left ventricular remodeling in patients with acute myocardial infarction.

  Blood was sampled on admission , and at 24 h , 3 days , 7 days , 2 weeks and 4 weeks in 24 patients with their first AMI.

• 17689746(Tumor Necrosis Factor-alpha): Acute myocardial infarction induced increases in plasma tumor necrosis factor-alpha and interleukin-10 are associated with the activation of poly(ADP-ribose) polymerase of circulating mononuclear cell.

  These results implicated that activation of PARP in MNC contributes to the increases in plasma TNF-alpha and IL-10 and is associated with systolic dysfunction of heart after AMI.

• 11420111(poly-ADP-ribose): Characterization of poly(ADP-ribose)polymerase from Crithidia fasciculata: enzyme inhibition by beta-lapachone.

  beta-Lapachone inhibited PARP , apparently by direct interaction with the enzyme.
