(Submitter supplied) We report the high-throughput profilings of HIF1 and histone modifications in human umbilical vein endothelial cells (HUVEC). By obtaining over two billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of HUVEC under normoxia and hypoxia. We find that HIF1binds to not only to transcriptional starting sites but also enhancer regions and that HIF1 binding sites were overlapped with lysine 4 trimethylatio, monomethylation and lysine 27 acetylation . more...

(Submitter supplied) Purpose: Jumonji-containing (jmjC) family of proteins are involved in epigenetic gene regulation through histone specific lysine demethylation. Previous studies have demonstrated that the expression of several members of this family is induced by hypoxia. However, the mechanisms by which lysine specific demethylases (KDMs) are regulated under hypoxia and how they affect angiogenesis, the primary method to restore blood oxygen, remains unknown. more...

(Submitter supplied) Hypoxia inducible factor (HIF) is the major transcriptional regulator of cellular responses to hypoxia. The two principal HIF-a isoforms, HIF-1a and HIF-2a, are progressively stabilized in response to hypoxia and form heterodimers with HIF-1b to activate a broad range of transcriptional responses. Here we report on the pan-genomic distribution of isoform-specific HIF binding in response to hypoxia of varying severity and duration, and in response to genetic ablation of each HIF-a isoform. more...

(Submitter supplied) Un-physiological activation of hypoxia inducible factor (HIF) is an early event in most renal cell cancers (RCC) following inactivation of the von Hippel-Lindau tumor suppressor. Despite intense study, how this impinges on cancer development is incompletely understood. To test for the impact of genetic signals on this pathway, we aligned human RCC-susceptibility polymorphisms with genome-wide assays of HIF-binding and observed highly significant overlap. more...

(Submitter supplied) Hypoxia inducible factor (HIF) directs an extensive transcriptional cascade that transduces numerous adaptive responses to hypoxia. Pan-genomic analyses, using chromatin immunoprecipitation and transcript profiling, have revealed large numbers of HIF-binding sites that are generally associated with hypoxia-inducible transcripts, even over long chromosomal distances. However, these studies do not define the specific targets of HIF-binding sites and do not reveal how induction of HIF affects chromatin conformation over distantly connected functional elements. more...

(Submitter supplied) Histone lysine (K) residues, which are modified by methyl- and acetyl-transferases, diversely regulate RNA synthesis. Unlike the ubiquitously activating effect of histone K acetylation, the effects of histone K methylation vary with the number of methyl groups added and with the position of these groups in the histone tails. Histone K demethylases (KDMs) counteract the activity of methyl-transferases and remove methyl group(s) from specific K residues in histones.KDM3A (also known as JHDM2A or JMJD1A) is an H3K9me2/1 demethylase. more...

(Submitter supplied) Histone demethylation has important roles in regulating gene expression and forms part of the epigenetic memory system that regulates cell fate and identity, by still poorly understood mechanisms. Here we examined the role played by the histone demethylase Kdm3a, which demethylates lysine 9 of histone H3, during cellular differentiation. Using F9 mouse embryonal carcinoma cells as a model for progression through terminal differentiation, we showed that Kdm3a is essential to differentiation into parietal endoderm-like (PE) cells. more...
