Description
We have identified SOX2 as a new oncogene and a likely driver of recurrent 3q26.3 amplifications in lung Squamous Cell Carcinoma. SOX2 is a crucial transcription factor implicated in Embryonic and Neural Stem Cells, that we found widely activatd in human lung SCC. This part of the study aimed at analyzing the transcriptomic consequences of SOX2 overexpression in a simple in vitro model (human lung squamous immortalized cells).

- Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
Filtered selection coupled with support vector machines generate functionally relevant prediction model for colorectal cancer. In this study, we built a model that uses Support Vector Machine (SVM) to classify cancer and normal samples using Affymetrix exon microarray data obtained from 90 samples of 48 patients diagnosed with CRC. From the 22,011 genes, we selected the 20, 30, 50, 100, 200, 300 and 500 genes most relevant to CRC using the Minimum-RedundancyMaximum-Relevance (mRMR) technique. With these gene sets, an SVM model was designed using four different kernel types (linear, polynomial, radial basis function and sigmoid).

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Regulation of gene expression at the post-transcriptional level plays an indispensable role during TGFbeta-induced EMT and metastasis. This regulation involves a transcript-selective translational regulatory pathway in which a ribonucleoprotein (mRNP) complex, consisting of heterogeneous nuclear ribonucleoprotein E1 (hnRNP E1) and eukaryotic elongation factor 1A1 (eEF1A1), binds to a 3-UTR regulatory BAT (TGF activated translation) element and silences translation of Dab2 and ILEI mRNAs, two transcripts which are involved in mediating EMT. TGFbeta activates a kinase cascade terminating in the phosphorylation of hnRNP E1, by isoform-specific stimulation of protein kinase B/Akt2, inducing the release of the mRNP complex from the 3-UTR element, resulting in the reversal of translational silencing and increased expression of Dab2 and ILEI transcripts.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Phosphate is essential for healthy bone growth and plays an essential role in fracture repair. Although phosphate deficiency has been shown to impair fracture healing, the mechanisms involved in impaired healing are unknown. More recently, studies have shown that the effect of phosphate deficiency on the repair process varied based on the genetic strain of mice, which is not characterized.

Description
The molecular mechanisms by which individuals subjected to environmental heat stress either adapt or develop heat-related complications are not well understood. We analysed the changes in blood mononuclear gene expression patterns in human volunteers exposed to an extreme heat in a sauna (temperature of 78 6 C).

Illumina HiSeq 2500
Description
Mature B cells leave the bone marrow as naïve B cells and migrate to the secondary lymphoid organs where they encounter the antigen for the first time. This interaction stimulates B cells to rapidly grow and form characteristic histological structures called germinal center. In the germinal centers, B cells are targeted by mechanisms of genetic editing of the immunoglobulin loci, namely somatic hypermutation and class switch recombination, undergo selection for high affinity immunoglobulin receptors and are committed to differentiate into memory B cells or plasma cells. GCs display two histological areas the dark and the light zone that have been characterized as functionally distinct compartments through which B cells recycle multiple times during the germinal center reaction. Overall design: Naïve, germinal center and memory B cells were isolated from three independent donors each.

Description
The 24R,25-dihydroxyvitamin D metabolite (24R,25D) has long been suspected of participating to bone fracture repair. We used Cyp24a1-deficient mice, unable to produce 24R25D, to observe gene expression in callus tissue compared to that of control littermates.
