Description
In a randomized controlled dietary intervention study we compared an isocaloric Healthy Nordic diet with the average Nordic diet for influence on peripheral blood mononuclear cells (PBMC) gene expression. We studied obese adults with features of the metabolic syndrom, n=66. There was no significant difference in age, BMI, or gene expression between the groups before the intervention. The intervention lasted for 18-24 weeks.
Publication Title

Description
The nuclear hormone 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) regulates its target genes via activation of the transcription factor vitamin D receptor (VDR) far more specifically than the chromatin modifier trichostatin A (TsA) via its inhibitory action on histone deacetylases. We selected the thrombomodulin gene locus with its complex pattern of three 1,25(OH)2D3 target genes, five VDR binding sites and multiple histone acetylation and open chromatin regions as an example to investigate together with a number of reference genes, the primary transcriptional responses to 1,25(OH)2D3 and TsA. Transcriptome-wide, 18.4% of all expressed genes are either up- or down-regulated already after a 90 min TsA treatment; their response pattern to 1,25(OH)2D3 and TsA sorts them into at least six classes. TsA stimulates a far higher number of genes than 1,25(OH)2D3 and dominates the outcome of combined treatments. However, 200 TsA target genes can be modulated by 1,25(OH)2D3 and more than 1000 genes respond only when treated with both compounds. The genomic view on the genes suggests that the degree of acetylation at transcription start sites and VDR binding regions may determine the effect of TsA on mRNA expression and its interference with 1,25(OH)2D3. Our findings may have implications on dual therapies using chromatin modifiers and nuclear receptor ligands.

Description
Research regarding the role of astrocytes as -amyloid (A) degrading cells has broadened our view about the mechanisms how these common glia cells function in Alzheimers disease (AD). Based on previous studies adult mouse astrocytes are able to degrade A deposits from AD mouse model and human brain tissue sections ex vivo, contrary to neonatal astrocytes. In this study, we studied the possible altered gene expression profiles of adult and neonatal astrocytes cultured for 22 h on top of the A burdened tg APdE9 or wild-type mouse brain sections using whole genome microarrays. Quantitative RT-PCR analysis confirmed the significant up-regulation of HtrA serine peptidase 1 (Htra1), metallopeptidase 9 (Mmp9), phosphate regulating gene with homologies to endopeptidases on the X chromosome (Phex) and scavenger receptor class A, member 5 (Scara5) in adult astrocytes, whereas neonatal astrocytes up-regulated Mmp9 and down-regulated genes related to cholesterol transport and synthesis: apolipoprotein E (Apoe), 24-dehydrocholesterol reductase (Dhcr24) and 3-hydroxy-3-methylglutaryl-CoA synthase 1 (Hmgcs1). These findings brought out novel genes which expression is altered during A clearance in adult and neonatal astrocytes ex vivo.
