BACKGROUND AND OBJECTIVES Since statins and angiotensin receptor blockers are a frequently prescribed combination in patients with atherosclerotic cardiovascular diseases, we tested the interactive effects of simvastatin and losartan on atherosclerosis in apolipoprotein E (apoE)(-/-) mice. MATERIALS AND METHODS Apolipoprotein E(-/-) mice were fed a(More)
Renal ischemia-reperfusion injury is a major cause of acute kidney injury. We previously found that renal A(1) adenosine receptor (A(1)AR) activation attenuated multiple cell death pathways including necrosis, apoptosis, and inflammation. Here, we tested whether induction of cytoprotective sphingosine kinase (SK)-1 and sphingosine-1-phosphate (S1P)(More)
The role for the endothelial sphingosine-1-phosphate 1 receptor (S1P1R) in acute kidney injury (AKI) remains unclear as germline endothelial S1P1R deletion is embryonically lethal. Here, we generated conditional endothelial S1P1R deficiency by crossing mice with floxed S1P1R with mice expressing a tamoxifen-inducible form of Cre recombinase under the(More)
The volatile anesthetic isoflurane protects against renal ischemia and reperfusion injury by releasing renal tubular TGF-β1. As adenosine is a powerful cytoprotective molecule, we tested whether TGF-β1 generated by isoflurane induces renal tubular ecto-5'-nucleotidase (CD73) and adenosine to protect against renal ischemia and reperfusion injury. Isoflurane(More)
Interleukin-6 (IL-6), which is increased in patients who are suffering from septic shock, is an important mediator of the inflammatory response. Here, we examined the priming effect of lipoteichoic acid (LTA) and lipopolysaccharide (LPS) on IL-6 production in a monocyte-like cell line. THP-1 cells were primed by treatingwith a low or high dose of LTA(More)
We studied centrifugation-mediated mechanical stress induced Tumor necrosis factor (TNF)-α production in the monocyte-like cell line THP-1. The induction of TNF-α by mechanical stress was dependent on the centrifugation speed and produced the highest level of TNF-α after 1 h of stimulation. TNF-α production returned to normal levels after 24 h of(More)
