Description
From a clinical and molecular perspective, colon cancer (CC) is a heterogeneous disease but to date no classification based on high-density transcriptome data has been established. The aim of this study was to build up a robust molecular classification ofmRNA expression profiles (Affymetrix U133Plus2) ofa large series of 443 CC and 19 non-tumoral colorectal mucosas, and to validate it on an independent serie of 123 CC and 906 public dataset.We identified and validated six molecular subtypes in this large cohort as a combination of multiple molecular processes that complement current disease stratification based on clinicopathological variables and molecular markers. The biological relevance of these subtypes was consolidated by significant differences in survival. These insights open new perspectives for improving prognostic models and targeted therapies.

Description
To characterize gene response in RPE65-/- mouse model of Lebers congenital amaurosis during progression of the disease, we analyzed differential gene expression in retinae early in the development of the disease, namely before and at the onset of photoreceptor cell death in knock-out mice of 2, 4 and 6 months of age.

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Meiotic recombination is initiated by the Spo11 endonuclease, which directs DNA double strand breaks at discrete regions in the genome coined hotspots. Here we report the profiles and dynamics of histone modifications at the cores of mouse recombination hotspots in early meiotic prophase. To define the spectrum of possible regulators of histone methylation and acetylation at all stages of meiosis I, expression analyses of histone acetylases/deacetylases (HATs/HDACs) and and HMTs/HDMTs genes when comparing those expressed in spermatogonia, pre-leptotene and leptotene/zygotene versus pachytene meiotic stages.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
TGZ is an agonist of the nuclear receptor PPARgamma. This synthetic compound displays anticancer effects on breast cancer cells but some of them are PPARgamma independent. Delta-2-TGZ (delta-2-troglotazone) is a PPARgamma inactive TGZ derivative possessing a double bond adjoining the thiazolidinedione ring. This compound still displays anticancer efefcts. It is an interesting tool to study the PPARgamma-independent mechanisms.

Description
Life-threatening pulmonary influenza can be caused by inborn errors of type I and III IFN immunity. We report a 5 year-old child with severe pulmonary influenza at 2 years. She is homozygous for a loss-of-function IRF9 allele. Her cells activate gamma-activated factor (GAF) STAT1 homodimers but not interferon-stimulated gene factor 3 (ISGF3) trimers (STAT1/STAT2/IRF9) in response to IFN-a2b. The transcriptome induced by IFN-a2b in the patient's cells is much narrower than that of control cells; however, induction of a subset of interferon-stimulated gene transcripts remains detectable. In vitro, the patient's cells do not control three respiratory viruses, influenza A virus (IAV), parainfluenza virus, and respiratory syncytial virus. These phenotypes are rescued by wild-type IRF9, whereas silencing IRF9 expression in control cells increases viral replication. However, the child has controlled various common viruses in vivo, including respiratory viruses other than IAV. Our findings show that human IRF9- and ISGF3-dependent type I and III IFN responsive pathways are essential for controlling IAV. Overall design: Total of 72 samples, 38 samples from primary fibroblasts and 34 samples from EBV-transformed B cells, were analyzed using paired-end RNA sequence data. Out of 38 samples from primary fibroblasts, 3 control samples are paired with no stimulation vs IFNa2b stimulation. Out of 34 samples from B-cells, 3 control samples are paired with no stimuliion vs IFNa2b stimulation. In addition to healthy control subjects, patients with AR complete STAT1 (STAT1 -/-) or STAT2 (STAT2 -/-) deficiency were analyzed for comparison.

We present single-cell mRNA-Sequencing of various endothelial and hematopoietic populations isolated from the mouse embryonic aorta at E10 and E11. Our study reveals the transcriptional dynamics occuring during endothelial to hematopoietic transition, the process responsible for the production of hematopoietic stem cells.

Description
The purpose was to determine AcP- and AcPb-dependent gene responses to IL-1 by virally-reconstituting AcP-deficient mouse embryonic cortical neurons with CD25 (control), full length AcP, AcPb or the combination of both. A control population was transduced with a CD25-expressing virus. Half the samples were stimulated with IL-1-beta for four hours, RNA was analyzed by microarray.
