Adenoviral RB2/p130 gene transfer inhibits smooth muscle cell proliferation and prevents restenosis after angioplasty.

1999

Abstract —Smooth muscle cell (SMC) proliferation that results in neointima formation is implicated in the pathogenesis of atherosclerotic plaques and accounts for the high rates of restenosis that occur after percutaneous transluminal coronary angioplasty, a widespread treatment for coronary artery disease. Endothelial lesions trigger intense proliferative signals to the SMCs of the subintima, stimulating their reentry into the cell cycle from a resting G 0 state, resulting in neointima formation and vascular occlusion. Cellular proliferation is negatively controlled by growth-regulatory or tumor-suppressor genes, or both, such as the retinoblastoma gene family members ( RB/p105, p107, RB2…

Islet beta-cell apoptosis triggered in vivo by interleukin-1beta is not related to the inducible nitric oxide synthase pathway: evidence for mitochon…

2003

IL-1beta is recognized as an effector cytokine contributing to islet beta-cell destruction during diabetes. We have previously shown in vitro that IL-1beta induces nitric oxide (NO) and beta-cell damage. Here, we show that IL-1beta administration in vivo to Wistar rats transiently increases manganese superoxide dismutase activity, whereas inducible NO synthase is not detected, and the levels of nitrate+nitrate do not change. Moreover, a significant decrease of mitochondrial aconitase, leading to a rise of hydroperoxides, and islet beta-cell apoptosis, involving caspase-3 and -8, is observed. Analysis of adhesion molecules in beta-cells showed that intercellular adhesion molecule-1 is highly…

Carbon monoxide improves cardiac energetics and safeguards the heart during reperfusion after cardiopulmonary bypass in pigs

2004

Ischemia-reperfusion injury, a clinical problem during cardiac surgery, involves worsened adenosine trisphosphate (ATP) generation and damage to the heart. We studied carbon monoxide ( CO) pretreatment, proven valuable in rodents but not previously tested in large animals, for its effects on pig hearts subjected to cardiopulmonary bypass with cardioplegic arrest. Hearts of CO-treated pigs showed significantly higher ATP and phosphocreatine levels, less interstitial edema, and apoptosis of cardiomyocytes and required fewer defibrillations after bypass. We conclude that treatment with CO improves the energy status, prevents edema formation and apoptosis, and facilitates recovery in a clinical…

Efficiency of transgenesis using sperm-mediated gene transfer: generation of hDAF transgenic pigs.

2000

SINCE the beginning of this century, replacement of failing human organs with their animal counterparts has been an interesting topic of debate for writers and scientists. In the 1960s, prolonged survival after kidney transplantation from chimpanzee to human was obtained in the United States and Europe. Nevertheless, both the progressive improvement in surgical technique and in immunosuppressant therapy and the availability of cadaveric organs and living donation have reduced the interest in xenotransplantation. Because of the increasing requests for organs and the lack of donors to meet that need, xenotransplantation has become a reliable option again for temporary organ replacement (eg, o…

hDAF expression in hearts of transgenic pigs obtained by sperm-mediated gene transfer.

2000

TRANSPLANTATON has been the choice option to treat successfully an increasing number of acute and chronic human pathologies with declining morbidity and mortality. However, availability of organs from human donors is limited and dramatically inadequate with respect to patient requests. Xenotransplantation from large-sized mammals has thus been reconsidered as a tool to overcome the present unbalance between organ offers and requests. Pigs have been chosen because they can be easily and cheaply bred; they do not raise ethical questions—their use as alimentary resources is generally admitted; and they possess organs largely human compatible for size, anatomical organization, and physiology. N…
