Protective ischaemia in patients: preconditioning and postconditioning (2009)
Granfeldt, Asger, Lefer, David J., Vinten-Johansen, Jakob

Objective: Recent results have shown that 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors referred to as statins rapidly activate the protein kinase Akt/PKB in endothelial cells...
Lefer, Allan M., Lefer, David J.
The microcirculation undergoes a profound degree of endothelial dysfunction within minutes (i.e., 2.5 to 5 min) following reperfusion of ischaemic vasculature. This has been documented in the...

Up-regulation of proapoptotic genes has been reported in heart failure and myocardial infarction. To determine whether caspase genes can affect cardiac function, a transgenic mouse was generated....
CD8+-T-Cell Depletion Ameliorates Circulatory Shock in Plasmodium berghei-Infected Mice
Chang, Wun-Ling, Jones, Steven P., Lefer, David J., Welbourne, Tomas, Sun, Guang, Yin, Lijia, ...
The Plasmodium berghei-infected mouse model is a well-recognized model for human cerebral malaria. Mice infected with P. berghei exhibit (i) metabolic acidosis (pH < 7.3) associated with elevated...
Harada, Hirohisa, Pavlick, Kevin P., Hines, Ian N., Lefer, David J., Hoffman, Jason M., Bharwani, Sulaiman, ...
We have recently reported that female mice are protected to a much greater extent from the injurious effects of reduced-size liver ischemia and reperfusion (RSL+I/R) than are males by an...
Endothelial nitric oxide synthase overexpression attenuates congestive heart failure in mice
Jones, Steven P., Greer, James J. M., Van Haperen, Rien, Duncker, Dirk J., De Crom, Rini, Lefer, David J.
Congestive heart failure results in cardiovascular dysfunction and diminished vascular nitric oxide (NO) production. We hypothesized that overexpression of endothelial NO synthase (eNOS) within the...
The MEK1–ERK1/2 signaling pathway promotes compensated cardiac hypertrophy in transgenic mice
Bueno, Orlando F., De Windt, Leon J., Tymitz, Kevin M., Witt, Sandra A., Kimball, Thomas R., Klevitsky, Raisa, ...
Members of the mitogen-activated protein kinase (MAPK) cascade such as extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and p38 are implicated as important regulators of...
Cytoprotective effects of nitrite during in vivo ischemia-reperfusion of the heart and liver
Duranski, Mark R., Greer, James J.M., Dejam, Andre, Jaganmohan, Sathya, Hogg, Neil, Langston, William, ...
Nitrite represents a circulating and tissue storage form of NO whose bioactivation is mediated by the enzymatic action of xanthine oxidoreductase, nonenzymatic disproportionation, and reduction by...
