TranscriptomicsCalorie restriction-like effects of 30 days of resveratrol supplementation on energy metabolism and metabolic profile in obese humans
Resveratrol is a naturally occurring compound that profoundly affects energy metabolism and mitochondrial function and serves as a calorie restriction mimetic, at least in animal models of obesity. Here we treated 10 healthy, obese men with placebo and 150 mg/day resveratrol in a randomized double-b...

TranscriptomicsPhotorespiratory stress in catalase deficient plants
Hydrogen peroxide (H2O2) can act as a signaling molecule that influences various aspects of plant growth and development, including stress signaling and cell death. To unravel the molecular mechanisms that regulate the response towards an impact of increased H2O2 levels in plant cells, we focused on...

TranscriptomicsArabidopsis GLYCOLATE OXIDASE 1 and 2 display divergent roles under conditions promoting photorespiration
Hydrogen peroxide (H2O2) can act as a signaling molecule that influences various aspects of plant growth and development, including stress signaling and cell death. To unravel the molecular mechanisms that regulate the response towards an impact of increased H2O2 levels in plant cells, we focused on...

TranscriptomicsGene deletion expression profiles of yeast chromatin modifiers
Packaging of DNA into chromatin has a profound impact on gene expression. To understand how changes in chromatin influence transcription, we analyzed 165 mutants of chromatin machinery components in Saccharomyces cerevisiae. mRNA expression patterns change in 80% of mutants, always with specific eff...

TranscriptomicsComparison of lymph node negative (N0) and lymph node metastasis (N+) head and neck squamous-cell carcinomas (HNSCC)
A classifier was build on 82 training samples to differentiate between lymph node negative (N0) and lymph node metastasis (N+) head and neck squamous-cell carcinomas (HNSCC). The 102 predictor genes that resulted from this classifier where then validated against a independent validation set.

TranscriptomicsPreadipocytes of T2DM patients display an intrinsic gene expression profile of decreased differentiation capacity
Insulin resistance and Type 2 Diabetes Mellitus (T2DM) are associated with increased adipocyte size, altered secretory pattern and decreased differentiation of preadipocytes. To identify the underlying molecular processes in preadipocytes of T2DM patients that are a characteristic of the development...

GenomicsSalt augments macrophage-driven host defense in the skin
Immune cells regulate a hypertonic microenvironment in the skin; however, possible functions of increased skin Na+ concentrations are unknown. We found that Na+ accumulated at the site of bacterial skin infections in humans and in mice. We used the protozoan parasite Leishmania (L.) major as a model...

TranscriptomicsPFOS and PFHxS decrease lipoprotein production
The effect of perfluoroalkyl sulfonates on lipoprotein metabolism was investigated in APOE*3-Leiden.CETP mice with a humanized lipoprotein profile. Perfluorohexane sulfonate and perfluorooctane sulfonate markedly reduced both plasma TG and TC by decreasing nonHDL-C and HDL-C accompanied by a reducti...

GenomicsGenome-wide maps of chromatin state in HSC, Pro B and mature B cells
We have used a genome-wide ChIP-sequencing approach to define and investigate the dynamics of the cis-regulatory landscape in three developmental stages of the murine hematopoietic system. To this end, we have compared the profiles of H3K4me3, H3K4me1, H3K27ac, H3K27me3 and H3K9me2 in HSCs, committe...
