We show that development of transplant CAD is associated with a particular cytokine profile in myocardial biopsies characterized by a late (i.e., 1 year) increase in tumor necrosis factor-alpha and interferon-gamma gene expression, which precede and potentially contribute to the development of allograft vasculopathy, further supporting a role for inflammation and the pathogenesis of transplant CAD in humans.
Our data suggest that GM1 is a key player in the induction of vascular insulin resistance after short- or long-term exposure to TNFα and is a good extracellular target for prevention and cure of vascular diseases.
In conclusion, DMF prevented abnormal proliferation in VSMCs by G1 cell cycle arrest via p21 upregulation driven by Nrf2 and p53 activity, and had a beneficial effect on TNF-α-induced apoptosis and dysfunction in endothelial cells through Nrf2-NQO1 activity suggesting that DMF might be a therapeutic drug for patients with vascular disease.
CAT and GPX activity and mRNA did not increase in high glucose only in adolescents with angiopathy (0.35 +/- 0.09; 4.2 +/- 0.1 and 0.52 +/- 0.14; 2.4 +/- 0.9, respectively).MnSOD did not change in any group.
At high glucose concentrations, the activity and mRNA expression of CuZnSOD increased similarly in all groups (diabetic subjects with angiopathy: 0.93 +/- 0.26 units/mg protein, 9.4 +/- 2.1 mRNA); that of CAT and GPX increased in only control subjects and diabetic subjects without angiopathy (diabetic subjects with angiopathy: 0.33 +/- 0.09 units/mg protein and 5.0 +/- 1.4 mRNA; 0.54 +/- 0.10 units/mg protein and 2.3 +/- 1.0 mRNA, respectively).MnSOD did not change in any group.
The ALA16VAL-MnSOD gene single nucleotide polymorphism (SNP) has shown to modulate risk factors of several metabolic and vascular diseases, such as blood glucose (GLU) and lipid levels.
Common polymorphisms in VKORC1, the gene coding for VKORC1, have been found to affect the dose response to vitamin K antagonists, and to confer an increased risk of vascular diseases in a Chinese population.
To know the association of ALDH2/AHD2 polymorphism with diabetic vasculopathy and neuropathy, a total of 158 patients with type 2 diabetes were divided into four groups on the basis of ALDH2 "activity" and ADH2 "superactivity."
