MetabolomicsSuboxic DOM is bioavailable to surface prokaryotes in a simulated overturn of an oxygen minimum zone, Devil’s Hole, Bermuda
Oxygen minimum zones (OMZs) are expanding due to increased sea surface temperatures, subsequent increased oxygen demand through respiration, reduced oxygen solubility, and thermal stratification driven in part by anthropogenic climate change. Devil's Hole, Bermuda is a model ecosystem to study OMZ m...

TranscriptomicsRNA-seq of Chlamydomonas reinhardtii exposed to inorganic or methylmercury
This study aims at investigating the link between internalized inorganic or methyl Hg and the global expression of genes, obtained by high-throughput sequencing (RNA-Seq), in the microalga Chlamydomonas reinhardtii. Algal cells were exposed two hours in a simplified artificial medium spiked with ser...

TranscriptomicsRUNX1 reshapes the epigenetic landscape at the onset of hematopoiesis
Cell fate decisions during hematopoiesis are governed by lineage-specific transcription factors, such as RUNX1, SCL/TAL1, FLI1 and C/EBP family members. In order to gain insight about how these transcription factors regulate the activation of hematopoietic genes during embryonic development, we meas...

TranscriptomicsDifferential RISC association of endogenous human microRNAs predicts their inhibitory potential
It has previously been assumed that the generally high stability of microRNAs (miRNAs) reflects their tight association with Argonaute (Ago) proteins, essential components of the RNA-induced silencing complex (RISC). However, recent data have suggested that the majority of mature miRNAs are not, in ...

TranscriptomicsBinary cell fate decision as high-dimensional critical state transition
During commitment of a multipotent stem or progenitor cell to a particular lineage, a large number of genes alter their expression in a coordinated manner orchestrated by the gene regulatory network (GRN). The constraints imposed by the GRN govern how cells move in the high-dimensional gene expressi...

GenomicsCytokine-mediated differentiation reflects genome-wide loss of a uSTAT transcriptional program
uSTAT transcriptional program HPC7 cells were fixed with either 1% formaldehyde for 10 mins. Chromatin was isolated, sonicated for 7 mins (30 sec on, 30 sec off), and specific antibodies were used to pull down the transcription factors of insterest after a pre-clearing step. Chromatin was washed, de...

TranscriptomicsGenome heterogeneity in Lactobacillus helveticus: Rethinking a “niche specialist”*
Lactobacillus helveticus is a rod-shaped lactic acid bacterium that is widely used in the manufacture of fermented dairy foods and for production of bioactive peptides from milk proteins. Although L. helveticus is commonly associated with milk environments, phylogenetic studies show it is closely r...

TranscriptomicsAnalysis of a fungus-specific transcription factor family, the Candida albicans zinc cluster proteins, by artificial activation
The zinc cluster proteins are a family of transcription factors that are unique to the fungal kingdom. In the pathogenic yeast Candida albicans, zinc cluster transcription factors control the expression of virulence-associated traits and play key roles in the development of antifungal drug resistanc...

GenomicsThree distinct patterns of histone H3Y41 phosphorylation mark active genes
The aim of the project was to identify the global distribution of H3Y41ph and correlate its presence with the transcription factor STAT5 and the active histone modification H3K4me3. This was done in human erythroid leukaemia cells (HEL). HEL cells were treated with DMSO or a JAK2 inhibitor (TG101209...

TranscriptomicsmiR-122 as a Regulator of Mitochondrial Metabolic Gene Network in Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is the leading cause of cancer-related deaths worldwide, reflecting the need for a better understanding of hepatocarcinogenesis. In this study, we examined the genome-wide expression profiles of both miRNAs and mRNAs from paired tumor and adjacent non-tumor tissues fro...
