Affymetrix Rat Genome U34 Array (rgu34a)
Description
mRNA gene expression was measured in intact female Sprague-Dawley rats at 6 (young), 26 (adult) and 52 (older) weeks of age at the time of fracture. Samples were collected at 0, 0.4, 1, 2, 4, and 6 weeks after fracture. RNA from two rats were pooled for each Affymetrix Rat U34A array. Mid-shaft, simple, transverse left femoral fractures were induced after retrograde intramedullary rod fixation with a Bonnarens and Einhorn device. Samples were collected from one third of the femoral length, centered on the fracture site, including the external callus, cortical bone, and marrow elements.

Description
Study of rat femur fracture healing in young (6 weeks old), adult (26 weeks old), and older (52 weeks old) rats with samples collected at 0 time (no fracture) and at 0.4, 1, 2, 4, and 6 weeks after fracture. RNA from two rats were pooled for each array.

- Affymetrix Rat Genome U34 Array (rgu34a)
Description
mRNA used for the analysis of these microarrays were previously analyzed for 34 genes by reverse transcription - polymerase chain reaction in Desai BJ et al., J.Orthop.Trauma 17: 689-698, 2003. These two data sets were subsequently studied to compare the results from these two different methods for mRNA quantitation. The comparison was publised in "Comparison of mRNA gene expression by RT-PCR and DNA microarray" by W. Etienne, M.H. Meyer, J. Peppers, and R.A. Meyer, Jr., BioTechniques 36 (4): 618-626, April 2004.

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 understand the link between invasion behavior and the steps of metastasis formation, we isolated invasive subpopulations from MDA-MB-231 cells in vitro using matrigel coated boyden chambers. Whole genome transcriptional profiling was used to characterize the expression changes uniquely related to invasive abilities of these cells.

Illumina HiSeq 2000
Description
This experiment seeks to ascertain the transcriptional changes in the adult mouse hippocampus (CA1 subregion) that occur following viral knockdown of the histone variant H2A.Z. We are especially interested in understanding the role of this histone variant in memory formation and memory maintenance in the adult central nervous system. Overall design: This experiment includes 3 groups, each with 3 biological replicates. Samples S108, S109, and S110 are from controls infected with an AAV expressing a scrambled shRNA control. Samples A100, A101, A102, A104, A106, and A107 were infected with an AAV expressing an shRNA against H2A.Z. Samples A100, A101, and A102 were naive animals, whereas samples A104, A106, and A107 were trained in contextual fear conditioning.
Publication Title
Histone H2A.Z subunit exchange controls consolidation of recent and remote memory.
