HIF-1–dependent repression of equilibrative nucleoside transporter (ENT) in hypoxia
Extracellular adenosine (Ado) has been implicated as central signaling molecule during conditions of limited oxygen availability (hypoxia), regulating physiologic outcomes as diverse as vascular leak, leukocyte activation, and accumulation. Presently, the molecular mechanisms that elevate extracellular Ado during hypoxia are unclear. In the present study, we pursued the hypothesis that diminish...
متن کاملCharacterization of three novel members of the Arabidopsis thaliana equilibrative nucleoside transporter (ENT) family.
Research on metabolism of nucleotides and their derivatives has gained increasing interest in the recent past. This includes de novo synthesis, analysis of salvage pathways, breakdown and transport of nucleotides, nucleosides and nucleobases. To perform a further step towards the analysis of nucleoside transport in Arabidopsis, we incubated leaf discs with various radioactively labelled nucleos...
متن کاملEquilibrative nucleoside transporter 1 expression is downregulated by hypoxia in human umbilical vein endothelium.
Reduced oxygen level (hypoxia) induces endothelial dysfunction and release of the endogenous nucleoside adenosine. Human umbilical vein endothelium (HUVEC) function in an environment with 3% to 5% O2 and exhibit efficient adenosine membrane transport via human equilibrative nucleoside transporters 1 (hENT1). We studied whether adenosine transport and hENT1 expression are altered by hypoxia in H...
متن کاملEquilibrative nucleoside transporter 1 plays an essential role in cardioprotection.
To better understand the role of equilibrative nucleoside transporters (ENT) in purine nucleoside-dependent physiology of the cardiovascular system, we investigated whether the ENT1-null mouse heart was cardioprotected in response to ischemia (coronary occlusion for 30 min followed by reperfusion for 2 h). We observed that ENT1-null mouse hearts showed significantly less myocardial infarction c...
متن کاملTargeting the equilibrative nucleoside transporter ENT1 in Huntington disease
Huntington disease (HD) is a neurodegenerative disorder phenotypically characterized by progressive chorea, cognitive impairments and emotional disturbances. The crucial pathological hallmark of the disease is the atrophy of the striatum, with a remarkable loss of projecting medium spiny neurons. Among many disturbances in the homeostasis of the striatum reported in HD, it has been suggested th...
