Description
Multiple regulatory regions have the potential to regulate a single gene, yet how these elements combine to impact gene expression remains unclear. To uncover the combinatorial relationships between enhancers, we developed Enhancer-interference (Enhancer-i), a CRISPR interference-based approach that can prevent enhancer activation simultaneously at multiple regulatory regions. We applied Enhancer-i to promoter-distal estrogen receptor a binding sites (ERBS), which cluster around estradiol-responsive genes and therefore may collaborate to regulate gene expression. Targeting individual sites revealed predominant ERBS that are completely required for the transcriptional response, indicating a lack of redundancy. Simultaneous interference of different ERBS combinations identified supportive ERBS that contribute only when predominant sites are active. Using mathematical modeling, we find strong evidence for collaboration between predominant and supportive ERBS. Overall, our findings expose a complex functional hierarchy of enhancers, where multiple loci bound by the same transcription factor combine to fine tune the expression of target genes. Overall design: The effects of Enhancer interference (Enhancer-i) and control guide RNA treatment on the transcriptome before and after estrogen treatment, with 2 replicates per condition.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
We used phytochemical profiling techniques to generate a list of compounds present in each of 13 Equisetum arvense samples sourced globally. We used microarrays to detail the global programme of gene expression underlying the treatment of the model system Saccharomyces cerevisiae to a chosen number of these extracts. A thorough bioinformatic analysis was performed to identify the relationship between phytochemical and gene expression response profiles.

Description
The goal of this study was to determine the effects of dietary selenium levels on translational control of selenoprotein synthesis in mouse liver. Overall design: Wild type mice and mice expressing a mutant Sec-tRNA gene (TrspA37G) were fed diets supplemented with 0, 0.1, or 2 ppm selenium for 6 weeks. Livers were harvested and ribosome and mRNA profiles were generated by deep-sequencing using the Illumina HiSeq 2000.

Description
We carry out a differential RNAseq analysis of a row of sensilla on the anterior wing margin and find expression of many genes associated with pheromone and chemical perception. Overall design: We collected wings from wild type and from Poxn mutants that lack chemosensory sensilla on the wing. We performed RNAseq on three biological replicates from each genotype.
Publication Title
