Cardiac Overexpression of S100A6 Attenuates Cardiomyocyte Apoptosis and Reduces Infarct Size After Myocardial Ischemia‐Reperfusion
BACKGROUND Cardiomyocyte-specific transgenic mice overexpressing S100A6, a member of the family of EF-hand calcium-binding proteins, develop less cardiac hypertrophy, interstitial fibrosis, and myocyte apoptosis after permanent coronary ligation, findings that support S100A6 as a potential therapeutic target after acute myocardial infarction. Our purpose was to investigate S100A6 gene therapy f...
متن کاملMyocardial Infarct Size and Location
Recent infarcts were compared with the anatomic boundaries of the involved vascular bed in human hearts to determine the amount and location of necrosis in relation to the myocardium at risk. The coronary arteries were injected with BaSo4 in 18 human hearts with 3-16-day-old infarcts. Thin (3-4-mm) slices were cut at 10-15-mm intervals, photographed, x-rayed and used for histologic analysis. In...
متن کاملRelationship Between Myocardial Infarct Size
We compared myocardial infarct size produced by permanent occlusion of the middle left anterior descending (LAD) or circumflex (LCx) coronary artery in the anesthetized dog. The dogs were killed 3-10 days later, and the occluded coronary bed was visualized by postmortem arteriography. The outlines of the infarct and occluded bed were marked on tracings of weighed left ventricular (LV) rings and...
متن کاملMyocardial Infarct Size in Humans
Background. The influence of coronary collateral vessels on infarct size in humans remains controversial, partly because no previous study has examined the impact of collaterals present at the onset of acute myocardial infarction on infarct size. Methods and Results. The present study used the data base of the Thrombolysis in Myocardial Infarction (TIMI) Phase I trial to correlate the presence ...
متن کاملHuman thrombopoietin reduces myocardial infarct size, apoptosis, and stunning following ischaemia/reperfusion in rats.
AIMS Thrombopoietin (Tpo) is known for its ability to stimulate platelet production. However, it is currently unknown whether Tpo plays a physiological function in the heart. METHODS AND RESULTS We assessed the potential protective role of Tpo in vitro and in vivo in two rat models of myocardial ischaemia/reperfusion. Tpo receptor (c-mpl) message was detected in the heart using RT-PCR, and th...
