(Submitter supplied) Recently, we identified a population of Oct4+Sca-1+Lin-CD45- very small embryonic-like stem-cells (VSELs) in adult tissues. Open chromatin structure of pluripotency genes and genomic imprinting-related epigenetic mechanisms maintain pluripotency and quiescence of VSELs, respectively. However, global transcriptome signature of this rare stem-cell population remains elusive. Here, we demonstrate by genomewide gene-expression analysis with a small number of highly purified murine bone-marrow (BM)-derived VSELs, that Oct4+ VSELs i) express a similar, yet nonidentical, transcriptome as embryonic stem-cells (ESCs), ii) up-regulate cell-cycle checkpoint genes, iii) down-regulate genes involved in protein turnover and mitogenic pathways, and iv) highly express Ezh2, a polycomb group protein. more...

(Submitter supplied) Analysis of the transcriptional differences between mouse ES cells from the D3 cell line and transformed beta-cells (MIN6 cell line) as determined by a direct comparative analysis of their transcriptome. The results show that 40% of transcripts were differentially expressed between D3 and MIN6 cells. There is thus a marked difference in the pattern of transcription between the ES cell and beta-cell genomes.

(Submitter supplied) The polycomb group (PcG) proteins function in gene silencing through histone modifications. They form chromatin-associated multiprotein complexes, termed polycomb repressive complex (PRC) 1 and PRC2. These two complexes work in a coordinated manner in the maintenance of cellular memories through transcriptional repression of target genes. EZH2 is a catalytic component of PRC2 and trimethylates histone H3 at lysine 27 to transcriptionally repress the target genes. more...

(Submitter supplied) Congenital heart disease is among the most frequent major birth defects. Epigenetic marks are crucial for organogenesis, but their role in heart development is poorly understood. Polycomb Repressive Complex 2 (PRC2) trimethylates histone H3 at lysine 27, establishing H3K27me3 repressive epigenetic marks that promote tissue-specific differentiation by silencing ectopic gene programs. We studied the function of the catalytic subunit of PRC2, EZH2, in murine heart development. more...

(Submitter supplied) The Polycomb Group proteins foster gene repression profiles required for proper development and unimpaired adulthood, and comprise the components of the PRC2 complex including the histone H3 lysine 27 (H3K27) methyltransferase Ezh2. How mammalian PRC2 accesses chromatin is unclear. We find that Jarid2 associates with PRC2 and stimulates its enzymatic activity in vitro. Jarid2 contains a Jumonji C domain, but is devoid of detectable histone demethylase activity. more...

(Submitter supplied) Once thought to be transcriptional noise, large non-coding RNAs (lncRNAs) have recently been demonstrated to be functional molecules. Cell type-specific expression patterns of lncRNAs suggest that their transcription may be regulated epigenetically. Using a custom-designed microarray, here we examine the expression profile of lncRNAs in embryonic stem (ES) cells, lineage-restricted neuronal progenitor cells (NPC), and terminally differentiated fibroblasts. more...

However, the mechanisms by which PcG proteins are recruited to their targets are largely unknown.

(Submitter supplied) BAP1 and ASXL1 interact to form a polycomb deubiquitinase complex that removes monoubiquitin from histone H2A lysine 119 (H2AK119Ub). However, BAP1 and ASXL1 are mutated in distinct cancer types, consistent with independent roles in regulating epigenetic state and malignant transformation. Here we demonstrate that Bap1 loss results in increased trimethylated histone H3 lysine 27 (H3K27me3), elevated Ezh2 expression, and enhanced repression of Polycomb Repressive Complex 2 (PRC2) targets. more...

We here report that Dnmt3L is required for the differentiation of ESC into primordial germ cells (PGC) through activation of the homeotic gene Rhox5. more...
