Illumina MouseWG-6 v2.0 expression beadchip
Description
This study presents transcription profiles for mouse axial progenitors, presomitic mesoderm and tailbud mesoderm. During vertebrate embryonic development, the formation of axial structures is driven by a population of stem-like cells (axial progenitors) that reside in a region of the tailbud called the chordoneural hinge (CNH) where. We have compared the CNH transcriptome with those of surrounding tissues and shown that the CNH and tailbud mesoderm are transcriptionally similar, and distinct from the presomitic mesoderm. Amongst CNH-enriched genes are several that are required for axial elongation, including Wnt3a, Cdx2, Brachyury/T and Fgf8, and androgen/estrogen receptor nuclear signalling components such as Greb1.

Illumina HiSeq 2000
Description
We report here that human mitochondria contain small RNA including microRNA, piRNA, tRNA, rRNA, and RNA repeats. Mitochondria from human cells were purified and RNA isolated. Small RNAs were purified, library generated and analyzed by Illumina Hiseq 2000 system. The sequencing generated 19.5 and 17.7 million reads from HEK-293 and HeLa respectively. 91% and 97% sequences of HEK293 and HeLa respectively were annotated to various classes of small RNA. The total percentage of 4.21 and 2.58 sequences from HEK293 and HeLa respectively was found to be of miRNA. Further, we found only 1.2 % sequences from both the libraries aligned to mitochondrial genome. These results suggest that there is efficient transport of nuclear encoded small RNA to mitochondria. The small RNA in mitochondria may regulate critical cellular processes. Overall design: Analyzing the smallRNA in human mitochondria from two human cell lines (HEK-293 and HeLa).

Description
Cranial placodes contribute to all sense organs and sensory ganglia in the vertebrate head. Despite their diversity they originate from a common pool of Six1/Eya2+ progenitors. In a molecular screen we identify new factors upstream of the Six1/Eya2 cassette and use these to dissect the transcriptional hierarchy that controls progenitor specification. We find that although two different tissues, the lateral head mesoderm and the prechordal mesendoderm, induce placode progenitors, both initiate a common transcriptional state, but over time gradually impart regional character.

Description
The highly aggressive muscle cancer alveolar rhabdomyosarcoma (ARMS) is one of the most common soft tissue sarcoma of childhood, yet the outcome for unresectable and metastatic disease is dismal and unchanged for nearly 3 decades. To better understand the pathogenesis of this disease and to facilitate novel preclinical approaches, we previously developed a conditional mouse model of ARMS by faithfully recapitulating the genetic mutations observed in the human disease, i.e. activation of Pax3:Fkhr fusion gene with either p53 or Cdkn2a inactivation. In this report we show that this model recapitulates the immunohistochemical profile and the rapid progression of the human disease. We demonstrate that Pax3:Fkhr expression increases during late preneoplasia, but that tumor cells undergoing metastasis are under apparent selection for Pax3:Fkhr expression. At a whole genome level, a cross-species gene set enrichment analysis and metagene projection study showed that our mouse model is most similar to human ARMS when compared to other pediatric cancers. We have defined an expression profile conserved between mouse and human ARMS as well as a Pax3:Fkhr signature, including the target gene, SKP2. We further identified 7 druggable kinases over-expressed across species. The data affirms the accuracy of this genetically engineered mouse model.
