Nucleosome structure and positioning play pivotal roles in gene regulation, DNA repair and other essential processes in eukaryotic cells. Nucleosomal DNA is thought to be uniformly inaccessible to DNA binding and processing factors, such as MNase. Here, we show, however, that nucleosome accessibility and sensitivity to MNase varies. Digestion of Drosophila chromatin with two distinct concentrations of MNase revealed two types of nucleosomes: sensitive and resistant. MNase-resistant nucleosome arrays are less accessible to low concentrations of MNase, whereas MNase-sensitive arrays are degraded by high concentrations. MNase-resistant nucleosomes assemble on sequences depleted of A/T and enriched in G/C containing dinucleotides. In contrast, MNase-sensitive nucleosomes form on A/T rich sequences represented by transcription start and termination sites, enhancers and DNase hypersensitive sites. Lowering of cell growth temperature to ~10°C stabilizes MNase-sensitive nucleosomes suggesting that variations in sensitivity to MNase are related to either thermal fluctuations in chromatin fiber or the activity of enzymatic machinery. In the vicinity of active genes and DNase hypersensitive sites nucleosomes are organized into synchronous, periodic arrays. These patterns are likely to be caused by “phasing” nucleosomes off a potential barrier formed by DNA-bound factors and we provide an extensive biophysical framework to explain this effect.

The Hippo pathway regulates metazoan growth, acting through the transcriptional co-activators Yorkie (in Drosophila) and Yap and Taz (in vertebrates). Much attention has been focused on upstream regulators of Yorkie and its homologues. In contrast, the mechanisms by which they actually promote transcription have remained poorly understood. Genome-wide chromatin binding experiments support extensive functional overlap between Yorkie and GAF. Chromatin binding identifies thousands of Yorkie sites, the majority of which are associated with elevated transcription, based on genome-wide analysis of mRNA and histone H3K4Me3 modification. Our studies establish a molecular basis for transcriptional activation by Yorkie and implicate it as a global regulator of transcriptional activity in Drosophila. This is a dataset generated by the Drosophila Regulatory Elements modENCODE Project led by Kevin P. White at the University of Chicago. This dataset was generated in collaboration with Ken Irvine at HHMI/Rutgers University and Richard S. Mann at Columbia University. It contains ChIP-seq data (Illumina) for multiple transcription factor antibodies in Drosophila embryos and larval wing imaginal discs.

Loss of Lsd1 in Drosophila in specific cells of the Drosophila ovary results in increased BMP signaling outside the cap cell niche and an expanded germline stem cell (GSC) phenotype. To better characterize the function of Lsd1 in different cell populations within the ovary, we performed Chromatin immunoprecipitation coupled with massive parallel sequencing (ChIP-seq). This analysis shows that Lsd1 associates with a surprisingly limited number of sites in escort cells and fewer, and often, different sites in cap cells. These findings indicate that Lsd1 displays highly selective binding in specific cellular contexts.
