Illumina HiSeq 2500
Description
We report the RNAseq data obtained from 50.000-100.000 CD31-/CD45- pneumocytes isolated by FACS from mice harboring a normal dose or one extra copy of the Sirt1 gene, and a tamoxifen-inducible oncogenic KI alelle of KRasG12V after 4 weeks of tamoxifen treatment. Pneumocytes with the activated form of the inducible KRasG12V oncogene sere selected making use of the reporter gene LacZ (located next to the oncogene in the same polycistronic mRNA), by loading CD31-/CD45- pneumocytes with the LacZ-activated fuorogenic molecule FDG prior to FACS sorting. Overall design: Four replicates of each genetic group (Sirt1-WT and Sirt1-Tg) pneumocytes were used for this study. Sirt1-WT were used as reference controls.

Pneumocytes with the activated form of the inducible KRasG12V oncogene sere selected making use of the fluorescent reporter gene Katushka (located at an independent locus), by detecting Katushka fluorescence. Overall design: Four replicates of each genetic group (Sirt1-WT and Sirt1-Tg) pneumocytes were used for this study. Sirt1-WT were used as reference controls.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Background: Gliomas are the most common type of primary brain tumours, and in this group glioblastomas (GBMs) are the higher-grade gliomas with fast progression and unfortunate prognosis. Two major aspects of glioma biology that contributes to its awful prognosis are the formation of new blood vessels through the process of angiogenesis and the invasion of glioma cells. Despite of advances, two-year survival for GBM patients with optimal therapy is less than 30%. Even in those patients with low-grade gliomas, that imply a moderately good prognosis, treatment is almost never curative. Recent studies have demonstrated the existence of a small fraction of glioma cells with characteristics of neural stem cells which are able to grow in vitro forming neurospheres and that can be isolated in vivo using surface markers such as CD133. The aim of this study was to define the molecular signature of GBM cells expressing CD133 in comparison with non expressing CD133 cells. This molecular classification could lead to the finding of new potential therapeutic targets for the rationale treatment of high grade GBM.
Publication Title
Molecular analysis of ex-vivo CD133+ GBM cells revealed a common invasive and angiogenic profile but different proliferative signatures among high grade gliomas.

Description
Variant FhlA133 (Q11H, L14V, Y177F, K245R, M288K, and I342F) had eight- fold higher hydrogen production than FhlA wild-type under 30 min of anaerobic incubation in modified-complex 20 mM formate at 37C. The mechanism by which the FhlA133 mutations increase hydrogen production is by increasing the transcription of all of the genes activated by the native FhlA (FHL complex).

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Numerous CD11b+ myeloid cells are present within the dermis. They are very heterogeneous and can be divided in dermal DCs, tissue monocytes and tissue macrophages. At steady state, only CD11b+ DC migrate from the dermis to the skin draining lymph nodes whereas upon DNFB-induced inflammation, CD11b+ DC as well as dermal monocytes migrated to the lymph nodes. The objective of this study was to use gene expression profiling to rigorously identify the different subsets of dermal CD11b+ myeloid cells at steady state and upon inflammation and to characterize their functional potential.

Description
We used microarrays to compare interferon-alpha (IFNa)- and interferon-gamma (IFNg)-stimulated genes under an equivalent biological input. The goal was to compare IFNa- and IFNg-stimulated genes, as well as to identify common and distinct sets of type I and II ISGs.

Description
A number of studies find that metastasis suppressor proteins, including RhoGDI2, may function in part though controlling expression of genes regulating metastasis (reviewed in Smith and Theodorescu, Nature Reviews Cancer, 2009, PMID: 19242414). To uncover systematically gene expression patterns dependent on RhoGDI2 expression, we profiled gene expression in stably transfected control (GFP empty vector) UM-UC-3 bladder carcinoma cells (which have lost endogenous expression of RhoGDI2, as occurs commonly in the progression of bladder cancer PMID: 15173088), as well as stably transfected GFP-tagged RhoGDI2 expressing UM-UC-3 cells.

Description
Immunoglobulin light-chain amyloidosis (AL) is a rare clonal plasma cell (PC) disorder that remains largely incurable. AL and multiple myeloma (MM) share the same cellular origin, but while knowledge about MM PC biology has improved significantly, the same does not apply for AL. Here, we undertook an integrative phenotypic, molecular, and genomic approach to study clonal PCs from 22 newly-diagnosed AL patients. Through principal-component-analysis, we demonstrated highly overlapping phenotypic profiles between AL and MGUS or MM patients. However, in contrast to MM, highly-purified FACSs-sorted clonal PCs in AL (n=9/22) show virtually normal transcriptomes with only 68 deregulated genes as compared to normal PCs, including a few tumor suppressor (CDH1, RCAN) and pro-apoptotic (GLIPR1, FAS) genes. Notwithstanding, clonal PCs in AL (n=11/22) were genomically unstable with a median of 9 copy-number-abnormities (CNAs) per case; many of which similar to those found in MM. Whole-exome sequencing (WES) was performed in three AL patients and revealed a median of 10 non-recurrent mutations per case. Altogether, we showed that although clonal PCs in AL display phenotypic and CNA profiles similar to MM, their transcriptome is remarkably similar to that of normal PCs. First-ever WES revealed the lack of a unifying mutation in AL
