MetabolomicsTranscriptomic dynamics control rapid transition of core crop functions in 'lactating' pigeon

Pigeons (Columba livia) are widely kept as domesticated pets worldwide, and may have adapted to captivity through the evolutionarily specialized ability to produce ‘milk’ in the crops of both male and female parents via rapid proliferation and shedding of lipid- and protein-enriched epithelial ce...

GenomicsChromatin state dynamics during blood formation (ChIP-Seq)
We develop a new ChIpseq method (iChIP) to profile chromatin states of low cell number samples. We use IChIP to profile the chromatin dynamics during hematopoiesis across 16 different cell types which include the principal hematopoietic progenitors Examination of 2 different histone modifications in...

TranscriptomicsThe Nucleosome Landscape of P. falciparum Reveals Chromatin Architecture and Dynamics of Regulatory Sequences
In eukaryotes, the chromatin architecture has a pivotal role in regulating all DNA-related processes. For P. falciparum, the causative agent of human malaria, the nucleosome landscape of the extremely AT-rich intergenic regulatory regions is largely unexplored. With the aid of a highly controlled MN...

TranscriptomicsChromatin signatures at Notch regulated enhancers reveal large-scale changes in H3K56ac upon activation
To investigate the influence of chromatin organization and dynamics on the response to Notch signaling, we partitioned Drosophila chromatin using histone modifications and established This SuperSeries is composed of the SubSeries listed below. Refer to individual Series

ProteomicsQuantitative chromatin protein dynamics during replication origin firing in human cells (part 2)
Accurate genome duplication requires a tightly regulated DNA replication program, which relies on the fine regulation of origin firing. While the molecular steps involved in origin firing have been determined predominantly in budding yeast, the complexity of this process in human cells has yet to be...

GenomicsDynamics of yeast ISWI and CHD chromatin remodeler genomic association (part 1)
Chromatin remodelers influence genetic processes by altering nucleosome occupancy, positioning, and composition. In vitro, yeast ISWI and CHD remodelers require > 20 bp of extranucleosomal DNA for remodeling, but linker DNA in S. cerevisiae averages < 20 bp. To resolve this paradox, we have mapped t...

GenomicsETS Family Transcriptional Regulators Drive Chromatin Dynamics and Malignancy in Squamous Cell Carcinomas (ChIP-Seq II)
After characterizing super-enhancer-associated chromatin dynamics accompanied by malignant progression of skin stem cells, we show that ETS family members auto-regulate themselves and a cohort of cancer-associated super-enhancer transcription factors which together are essential for tumor maintenanc...
