Erythropoiesis must be tightly balanced to guarantee adequate oxygen delivery to all tissues in the body. This process relies predominantly on the hormone erythropoietin (EPO) and its transcription factor hypoxia inducible factor (HIF). Accumulating evidence suggests that oxygen-sensitive prolyl hydroxylases (PHDs) are important regulators of this entire(More)
Cysteinyl leukotrienes (cysLT), i.e., LTC4, LTD4, and LTE4, are lipid mediators derived from the 5-lipoxygenase pathway, and the cysLT receptors cysLT1-R/cysLT2-R mediate inflammatory tissue reactions. Although endothelial cells (ECs) predominantly express cysLT2-Rs, their role in vascular biology remains to be fully understood. To delineate cysLT2-R(More)
The 5-lipoxygenase (5-LO) pathway generates lipid mediators, i.e. the cysteinyl leukotrienes (cysLTs) LTC(4)/LTD(4) and LTB(4). CysLT receptors are expressed in endothelial cells (EC) and EC cysLT(2)-R activation induces diverse pro-inflammatory genes in vitro. We now report that LTD(4) promotes formation of an atherosclerosis-protective and anti-thrombotic(More)
The need for interdisciplinary programs for problem-based education increases. However, there is a substantial shortage of skilled boundary-spanning students, as prominently evidenced in the field of big data analytics. To solve this problem, this paper suggests a generic interdisciplinary IS curriculum process design model. The model considers education of(More)
Intracellular cAMP, the production of which is catalyzed by the α-subunit of the stimulatory G protein (Gsα), controls renin synthesis and release by juxtaglomerular (JG) cells of the kidney, but may also have relevance for the physiologic integrity of the kidney. To investigate this possibility, we generated mice with inducible knockout of Gsα in JG cells(More)
