- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
CHD8 is an ATPase of the SNF2 family involved in ATP-dependent nucleosome remodeling. Our data indicate that in the presence of progestin (R5020), a progesterone receptor (PR) agonist, CHD8 is recruited to a number of PR enhancers. To correlate CHD8 binding sites with CHD8-regulated gene expression we performed a transcriptomic analysis of T47D-MTVL cells transfected with a control siRNA or a siRNA specifically targeting CHD8 and stimulated during 6h with progestin or vehicle. CHD8-dependent genes presented lower induction of up-regulated genes and lower repression of down-regulated genes, indicating that CHD8 is required for progesterone-dependent regulation of a subset of genes.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Dent disease has multiple defects attributed to proximal tubule malfunction including low molecular weight proteinuria, aminoaciduria, phosphaturia and glycosuria. In order to understand the changes in kidney function of the Clc5 transporter gene knockout mouse model of Dent disease, we examined gene expression profiles from proximal tubules of mouse kidneys.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Most individuals with cystic fibrosis (CF) carry one or two mutations that result in a maturation defect of the full-length CFTR protein. The deltaF508 mutation results in a mutant protein that is degraded by the proteasome instead of progressing to the apical membrane where it functions as a cyclic AMP-regulated chloride channel. 4 phenylbutyrate modulates heat shock protein expression and promotes trafficking of deltaF508 thus permitting maturation and membrane insertion. The goal of this study was to gain insight into the genetic mechanism of PBA action through a large-scale analysis of gene expression. The Affymetrix genome spanning U133 microarray set was used to compare mRNA expression in untreated IB3-1 cell line cultures with cultures treated with 1mM 4-phenylbuyterate for 12 and 24 hr. IB3-1 deltaF508/W1282X) bronchial epithelial cells were cultured in T75 flasks with gentamicin-free LHC-8 medium. Cells were fed with 10 ml of media every 2 to 3 days. After reaching 80% confluence cells were treated with 1 mM PBA. A T75 flask of confluent IB3-1 cells was rinsed twice with ice cold Hanks buffer then scraped into 3ml of ice cold TRIzol (Gibco BRL) then rinsed with 3 ml ice cold TRIzol and the mRNA was isolated according to the TRIzol protocol. A total of 5 control cultures, 3 cultures with 12 hr BPA application and 3 cultures with 24 hr PBA application were processed

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Our results indicate that oxidation of TAF10 by LOXL2 induces its release from its promoters, leading to a block in TFIID-dependent gene transcription. Since TFIID complex is crucial for the expression of Nanog, Klf4, Sox2 and Oct4 and for maintaining the pluripotent state of embryonic stem cells, TAF10 oxidation by LOXL2 leads to inactivation of the pluripotency genes and a loss of pluripotent capacity in embryonic stem cells. Moreover, in vivo results demonstrate an essential role of LOXL2 in neural differentiation during zebrafish development: in the absence of LOXL2 the neural progenitor gene Sox2 is aberrantly overexpressed and neural differentiation is impaired.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Mechanical unloading by ventricular assist devices (VAD) leads to significant gene-expression changes often summarized as reverse remodeling. However, little is known on individual transcriptome changes during VAD-support and its relationship to non-failing hearts (NF). In addition no data are available for the transcriptome regulation during non-pulsatile VAD-support. Therefore we analysed the gene-expression patterns of 30 paired samples from VAD-supported (including 8 non-pulsatile VADs) and 8 non-failing control hearts (NF) using the first total human genome-array available.

Global gene expression analysis in nonfailing and failing myocardium pre- and postpulsatile and nonpulsatile ventricular assist device support.

Description
Perinatal nutritional imbalances may have long-lasting consequences on health and disease, increasing risk of obesity, insulin resistance, type 2 diabetes or cardiovascular disease. This idea has been conceptualized in the Developmental Origins of Health and Disease Hypothesis (DOHaD). In addition, there is evidence that such early-programmed phenotypes can be transmitted to the following generation(s). It is proposed that, environmentally induced, transmission of disease risk is mediated by epigenetic mechanisms.

- Affymetrix Clariom S Human array (clariomshuman)
Description
Metastasis of human tumours to LNs is a universally negative prognostic factor. LN stromal cells (SCs) play a crucial role in enabling T cell responses, and since tumour metastases modulate their structure and function, this interaction may suppress immune responses to tumour antigens. However the SC subpopulations that respond to infiltration of malignant cells into human LNs have not been defined. Using microarray, we sought to assess gene expression profiles of two distinct SC subpopulations isolated from melanoma-infiltrated LNs.
