GenomicsWhole-genome nucleosome mapping in meiotic diploid S. cerevisiae
We determined nucleosome positions throughout the genome in diploid S. cerevisiae undergoing early stages of synchronous meiosis. This study sought to assess if systematic reorganization of nucleosomes occurs during meiotic prophase at or near sites of DNA double strand break formation. Six samples ...

TranscriptomicsTranscription profiling of human Melanoma cell lines to investigate differences in wild-type p14ARF and mutant 14ARF
35 Melanoma cell lines hybridized to Affymetrix Hu133_Plus 2 microarrays were analysed for genes differentially expressed between cell lines carrying wild-type p14ARF and those with mutant 14ARF. All of these cell lines contained wild-type p53 (so that the effects of p14ARF mutations could be analys...

TranscriptomicsDifferential expression of mouse Grem1+ Vs. Grem1- bone-marrow cells
The gene expression of bone marrow cells of mice enriched for Gremlin1 vs control was measured (n=3). It is not known if endogenous adult mesenchymal stem cells (MSCs) exist.Following culture,perisinusoidal mesenchymal cells can clonally recapitulate the skeletal microenvironment, but this fails to ...

GenomicsGenome-wide mapping of meiotic double-strand breaks by sequencing Spo11 oligos.
The nonrandom distribution of meiotic recombination shapes patterns of inheritance and genome evolution, but chromosomal features governing this distribution are poorly understood. Formation of the DNA double-strand breaks (DSBs) that initiate recombination results in accumulation of Spo11 protei...

TranscriptomicsHigh expression of BMP pathway genes distinguishes a subset of Atypical Teratoid/Rhabdoid Tumors associated with shorter survival
Molecular profiling of tumors has proven a valuable tool for identification of prognostic and diagnostic subgroups in medulloblastomas, glioblastomas and other cancers. However, the molecular landscape of atypical teratoid / rhabdoid tumors (AT/RTs) remains largely unexplored. To address this issue,...

TranscriptomicsTGF-beta/Smad2/3 signaling directly regulates several miRNAs in mouse ES Cells and early embryos
Purpose: We aimed to identify miRNAs which are induced by the Activin/Nodal effectors, P-Smad2/3, in order to further our understanding of how P-Smad2/3 controls downstream gene expression in mouse ES cells to regulate crucial biological processes. Methods: We used a previously developed Tetracyclin...

GenomicsChIP Seq of Oct4, Nanog, H3K27me3 in Oct4+/+ and Oct4 +/- mES cells
Embryonic stem cell (ESC) pluripotency is governed by a gene regulatory network centred on the transcription factors Oct4 and Nanog. ESCs fluctuate between states of high and low Nanog expression that direct efficient or inefficient self-renewal. To date, robust self-renewing ESC states have only be...
