Illumina HumanHT-12 V4.0 expression beadchip
Description
LncRNA H19X was silienced in dermal fibroblats of systemic sclerosis patients with antisense oligonuclotides. The hypothesis tested in the present study was that H19X is an important factor in the development of TGFb-driven fibrosis. Results provide important information about the role H19X in fibroblasts in particolar on extracellular matrix production and cell cycle regulation.

- Affymetrix Chicken Genome Array (chicken)
Description
Comparative analysis of gene expression profiles in newly developed housing systems is important to understand gene functions in chicken for adaptation and possible gene-environment interactions among layer lines. Therefore, the objective of this study was to characterize the molecular processes that are different among the two layer lines Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB) using whole genome RNA expression profiles. Despite their approximately identical egg production performance these layer lines differ markedly in other phenotypic traits. The two layer lines were kept under the production environment of the newly developed small group housing system Eurovent German with two different group sizes and three tiers.
Publication Title
Differential gene expression from genome-wide microarray analyses distinguishes Lohmann Selected Leghorn and Lohmann Brown layers.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
To address the functional role of KDM6A in the regulation of Rhox genes, male and female mouse ES cells were transfected with a mixture of three small interfering RNA duplexes, each of which targets a different region of Kdm6a mRNA. We found that Kdm6a knockdown in mouse ES cells caused a decrease in expression of a subset of Rhox genes, Rhox6 and 9. Furthermore, Rhox6 and 9 expression was decreased in female ES cells but not male ES cells indicating that KDM6A regulates Rhox gene expression in a sexually dimorphic manner.

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
To address the functional role of MOF in mammalian X upregulation, male and female mouse ES cells were transfected with a mixture of three small interfering RNA duplexes, each of which targets a different region of Mof mRNA. We found that MOF knockdown in mouse ES cells caused a greater drop in expression of X-linked genes compared to autosomal genes, as measured by expression array analyses. The strongest effect was observed on medium-expressed X-linked genes.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Dosage compensation restores a balanced network of gene expression between autosomes and sex chromosomes in males (XY) and females (XX). In mammals, this is achieved by doubling the expression of X-linked genes in both sexes, together with X inactivation in females. X up-regulation may be controlled by DNA sequence based and/or epigenetic mechanisms that double the X output potentially in response to an autosomal counting factor. Human triploids with either one or two active X chromosomes (Xa) provide a mean to test X chromosome expression in the presence of three sets of autosomes, which will help understand the underlying mechanisms of X up-regulation.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Affymetrix 430 2.0 mouse arrays were used for expression analyses in undifferentiated and differentiated PGK12.1 ES cells. We found that the X:autosome expression ratios calculated from the mean expression values of X-linked and autosomal genes from microarrays was ~1.4 in undifferentiated female ES cells and then decreased to 1.2 in PGK12.1 cells after 15-day embryoid body differentiation. Thus, a substantial level of X upregulation is already evident in these ES cells prior to differentiation.

Description
The CCCTC-binding factor (CTCF) is a versatile transcriptional regulator required for embryogenesis, but its function in vascular development or in diseases with a vascular component is poorly understood. Here, we found that endothelial Ctcf is essential for mouse vascular development and limits accumulation of reactive oxygen species (ROS). Conditional knockout of Ctcf in endothelial progenitors and their descendants affected embryonic growth, and caused lethality at embryonic day 10.5 owing to defective yolk sac and placental vascular development. Analysis of global gene expression revealed Frataxin (Fxn), the gene mutated in Friedreich's ataxia (FRDA), as the most strongly downregulated gene in Ctcfdeficient placental endothelial cells. Moreover, in vitro reporter assays showed that Ctcf activates the Fxn promoter in endothelial cells. Reactive oxygen species (ROS) are known to accumulate in the endothelium of FRDA patients. Importantly, Ctcf deficiency induced ROS-mediated DNA damage in endothelial cells in vitro, and in placental endothelium in vivo. Taken together, our findings indicate that, Ctcf promotes vascular development, and limits oxidative stress in endothelial cells, perhaps through activation of Fxn transcription. These results reveal a function for a Ctcf–Fxn transcriptional pathway in vascular development, and also suggest a potential mechanism for endothelial dysfunction in FRDA. Overall design: Examination of transcriptome profiles of placental endothelial cells isolated from wildtype or ctcf defecient endothelial cells at E9.5
