(Submitter supplied) Epigenetic regulation is a fundamental mechanism mediating various cellular processes. However, epigenetic mechanisms in osteoclastogenesis remain incompletely understood. We performed MeDIP-seq analysis to investigate DNA methylation in osteoclasts derived from wild-type and Tet2Rank–/–; Tet3aRank+/– mice.

(Submitter supplied) Osteoclastogenesis is induced by the stimulation of RANKL. In the early stage of osteoclast differentiation, the osteoclast progenitor cells are primed by M-CSF, following a tightly controlled genetic program where specific sets of genes are up-regulated by RANKL. Some of them, for instance, control differentiation, cell-cell fusion and bone resorption. We used microarrays to detail the global program of gene expression underlying osteoclastogenesis and identified various up-regulated genes during this process.

(Submitter supplied) We report a novel role of ASXL1 protein in altering epigentic profile of osteoclast. ASXL1 is an ETP protein that bind to polycomb repressive complex. We asked if ASXL1 regulates osteoclast differentiation by maintaining balance between positive and negative epigenetic regulators. To address this question, we performed ChIP-seq using H3K27me3 and H3K4me3 antbody in day2 osteoclast. Our data reveals that there was a global loss of H3K27me3 in ASXl1-/- osteoclast which includes loss of this repressive methylation of NFATc1 promoter, which is a master regulator of osteoclastogenesis.

(Submitter supplied) Hypermethylation of tumor suppressor gene (TSG) promoters confers growth advantages to cancer cells, but how these changes arise is poorly understood. Here, we report that tumor hypoxia reduces the activity of oxygen-dependent TET enzymes, which catalyze DNA de-methylation through 5-methylcytosine oxidation. This occurs independently of hypoxia-associated alterations in TET gene expression, basal metabolism, HIF activity or nuclear reactive oxygen species, but directly depends on oxygen shortage. more...

(Submitter supplied) Genome wide DNA methylation profiling of normoxic and hypoxic non-small-cell lung cancer samples for 5mC and 5hmC. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation and hydroxymethylation profiles across 485,512 CpGs from DNA extracted from fresh-frozen tumor samples. Samples included 12 hypoxic and 12 normoxic tumor samples, with hypoxia determined according to the hypoxia metagene score (Buffa et al, Br J Cancer 2010). more...
