Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
The H4K16 acetyltransferase MOF plays a crucial role in dosage compensation in Drosophila, but has additional, global functions in gene control. We compared the molecular context and effect of MOF activity in male and female flies combining chromosome-wide mapping and transcriptome studies with analyses of defined reporter loci in transgenic flies. MOF distributes dynamically between two types of complexes, the Dosage Compensation Complex (DCC) and complexes containing MBD-R2, a global facilitator of transcription. These different targeting principles define the distribution of MOF between the X chromosome and autosomes and at transcription units with 5 or 3 enrichment.
Publication Title
The activation potential of MOF is constrained for dosage compensation.

Description
The MOF-containing NSL complex binds to many but not all promoters of active genes and potentially contributes to their proper gene expression. It is currently unknown what determines whether an active gene is bound or not. Here, we provide evidence that the NSL complex primarily targets active promoters of most housekeeping genes. There, it co-localizes with the chromatin remodeler NURF and the histone methyltransferase Trithorax. Moreover, despite binding to most housekeeping genes, the NSL complex regulates only a subset of them, which are depleted for certain insulator binding-proteins and enriched for the core promoter motif Ohler 5. We suggest that the combination of general chromatin factors and core promoter motifs is predictive for whether a housekeeping gene is transcriptionally regulated by the NSL complex.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
On triggering of the T cell receptor CD8 T lymphocytes downregulate expression of the transcription factor KLF2. KLF2 expression remains low as these cells differentiate to Cytotoxic T lymphocytes (CTL) but may be re-expressed depending on the local environmental signals.
Publication Title
The impact of KLF2 modulation on the transcriptional program and function of CD8 T cells.

Description
Analysis of strain-specific differences in gene expression in brains from a hydrocephalic mouse model of primary ciliary dyskinesia. The results identify genes that are differentially expressed between C57BL6/J and 129S6/SvEvTac brains. These genes encode proteins that function in a variety of cellular processes and include some that are relevant to hydrocephalus and cilia function, providing insight into the mechanisms underlying susceptibility to hydrocephalus.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The MYB gene family encodes transcription factors with a diverse range of functions in Arabidopsis. This study demonstrated that MYB5, which is expressed in trichomes and seeds, plays a central role in trichome and seed development. A microarray analysis of myb5 seeds identified other members of the MYB5 regulatory network.
Publication Title
The Arabidopsis MYB5 transcription factor regulates mucilage synthesis, seed coat development, and trichome morphogenesis.

Description
Children born to diabetic and obese or overweight mothers have a higher risk of heart disease at birth and later in life. Our previous work using chromatin immunoprecipitation sequencing revealed that late-gestation diabetes in combination with maternal high fat diet causes a distinct fuel-mediated epigenetic reprogramming of cardiac tissue during fetal cardiogenesis.
