View SamplesCarbon monoxide (CO) abrogates TNF-alpha mediated inflammatory responses in endothelial cells, yet, the underlying mechanism hereof is still elusive. We sought to explore potential mechanisms by which CO down-regulates VCAM-1 expression on TNF-alpha stimulated human umbilical vein endothelial cells (HUVEC). By genome-wide gene expression profiling and pathway analysis we studied the relevance of particular pathways for the anti-inflammatory effect of CO. In CO-releasing molecules-3 (CORM-3) stimulated HUVEC, significant changes in gene expression were found for genes implicated in the proteasome and porphyrine pathways. Although proteasome activities were increased by CORM-3, proteasome inhibitors did not abolish CORM-3s effect. Likewise, HO-1 inhibitors did not abrogate the ability of CORM-3 to down-regulate VCAM-1 expression. MAPK p38 was inhibited by CORM-3. Accordingly, VCAM-1 expression was down-regulated by the p38 inhibitor SB203580. Down-regulation of VCAM-1 by CORM-3 only occurred at concentrations that partly inhibit ATP production. Sodium azide and oligomycin paralleled the effect of CORM-3 in this regard. In conclusion, down-regulation of VCAM-1 by CORM-3 seems to be mediated via inhibition of p38 and mitochondrial respiration. Although CORM-3 up-regulates several genes in the ubiquitin proteasome sytem (UPS) or porphyrin pathway, there is no evidence that these changes are involved in the anti-inflammatory properties of CORM-3.

View SamplesSynaptic dysfunction is thought to underlie altered sociability in autism. However, the gene regulatory mechanisms that control synaptic protein expression in the context of social behaviour are poorly explored. Here we show that deletion of the large placental mammal specific miR379-410 cluster in mice leads to hypersocial behaviour, increased excitatory synaptic transmission and exaggerated expression of ionotropic glutamate receptor complexes in the hippocampus. Thus, interfering with miR379-410 could represent a novel therapeutic strategy for social deficits in autism.

View SamplesWe determined and classified Yak1-regulated genes in haploid strains of the Sigma1278b genetic background under vegetative growth conditions. For this purpose, we measured transcriptional profiles of different haploid MATa yeast strains of the following genotypes:YAK1 (468=YHUM0468), yak1 (1313=YHUM1313), strain YHUM1313 (yak1) carrying a high copy plasmid with YAK1 (1313Yhc) and strain YHUM1313 (yak1) carrying a high copy plasmid with YAK1 K398R (1313KDhc). All strains were grown in duplicate in YNB medium supplemented with tryptophan at 30 degrees Celsius to an optical density of 1.0 before extraction of total RNA and transcriptional profiling.
