Dicer is a key enzyme involved in the maturation of microRNAS (miRNAs). miRNAs have been shown to be regulators of gene expression participating in the control of a wide range of physiological pathways. To assess the role of Dicer and consequently the importance of miRNAs in the biology and functions of human endothelial cells (EC) during angiogenesis, we globally reduced miRNAs in ECs by speci...
BACKGROUND Oxidative stress activates endothelial innate immunity and disrupts endothelial functions, including endothelial nitric oxide synthase-derived nitric oxide bioavailability. Here, we postulated that oxidative stress induces sterol regulatory element-binding protein 2 (SREBP2) and microRNA-92a (miR-92a), which in turn activate endothelial innate immune response, leading to dysfunctiona...
RATIONALE Remote ischemic preconditioning (rIPC) with short episodes of ischemia/reperfusion (I/R) of an organ remote from the heart is a powerful approach to protect against myocardial I/R injury. The signal transduction pathways for the cross talk between the remote site and the heart remain unclear in detail. OBJECTIVE To elucidate the role of circulating nitrite in cardioprotection by rIP...
background: cyclosporine a (csa) is an immunosuppressant with therapeutic indications in various immunological diseases; however, its use is associated with chronic nephropathy. oxidative stress has a crucial role in csa-induced nephrotoxicity. the present study evaluates the protective effect of edaravone on csa-induced chronic nephropathy and investigates its antioxidant and nitric oxide modu...
Background: Cyclosporine A (CsA) is an immunosuppressant with therapeutic indications in various immunological diseases; however, its use is associated with chronic nephropathy. Oxidative stress has a crucial role in CsA-induced nephrotoxicity. The present study evaluates the protective effect of edaravone on CsA-induced chronic nephropathy and investigates its antioxidant and nitric oxide modu...
OBJECTIVES The proinflammatory marker C-reactive protein has been demonstrated to play a role in the development of atherosclerosis. Endothelin-1 and nitric oxide homeostasis is crucial for normal vasomotor function, limiting inflammatory activation and maintaining a nonthrombogenic endothelial surface. In addition to its vasoactive properties, endothelin-1 is also an inflammatory cytokine. We ...
