Leukotrienes 168-179 sphingosine kinase 2 Mus musculus 82-87 23043544-3 2012 A genetics-based approach using SphK2- and CCL2-null mice showed both SphK2 and CCL2 to be necessary for the induction of ischemic tolerance following preconditioning with hypoxia, the hypoxia-mimetic cobalt chloride, or the sphingosine-1-phosphate (S1P) agonist FTY720. cobaltous chloride 201-216 sphingosine kinase 2 Mus musculus 70-75 22393932-6 2012 Ethanol exposure in 7-day-old mice induced sphingosine kinase 2 activation and increased the brain level of S1P transiently 2-4 h after exposure, followed by caspase 3 activation that peaked around 8 h after exposure. Ethanol 0-7 sphingosine kinase 2 Mus musculus 43-63 22393932-8 2012 These results indicate that ethanol activates sphingosine kinase 2, leading to a transient increase in S1P, which may be involved in neuroapoptotic action of ethanol in the developing brain. Ethanol 28-35 sphingosine kinase 2 Mus musculus 46-66 22393932-8 2012 These results indicate that ethanol activates sphingosine kinase 2, leading to a transient increase in S1P, which may be involved in neuroapoptotic action of ethanol in the developing brain.
