Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that is characterized by increased circulating androgen levels, anovulatory infertility, and frequently, insulin resistance and hyperinsulinemia.The abnormity of oocyte nuclear maturity is the main reason for anovulatory infertility and pregnancy loss in PCOS patients.The bidirectional exchanges between oocyte and contiguous CCs are important for oocyte competence acquisition, early embryonic development and CC expansion.Gene expression profiles of CCs has been suggested to predict embryo development and pregnancy outcome.
Publication Title

Description
Transcriptomics analyses in these Zn-deficient rats revealed the molecular basis of ESCC abrogation by miR-31 knockout: Egln3, a negative regulator of NF-FB, was shown to be a direct miR-31 target; miR-31 inhibition/deletion resulted in suppression of miR-31-associated-EGLN3-NF-KB controlled inflammatory pathways.

- Affymetrix Human Genome U95 Version 2 Array (hgu95av2)
Description
The specific genes that influence neuroblastoma biology and are targeted by genomic alterations remain largely unknown. We quantified mRNA expression in a highly annotated series of 101 prospectively collected diagnostic neuroblastoma primary tumors and the expression profiles were determined using Affymetrix U95Av2 arrays. Comparisons between the sample groups allow the identification of genes with localized expression patterns. This study demonstrates that the genomic data can be used to subcategorize the disease into molecular subsets and the regional copy number alterations are correlated with a broad number of transcriptional alterations genome wide. This data also suggests that multiple genes from several discrete regions of the human genome co-operate to supress neuroblastoma tumorigenesis and progression.
Publication Title

Description
The gas-1(fc21) mutation affects the 49 kD subunit of complex I, decreasing the rate of complex I-dependent oxidative phosphorylation. This is a model for human mitochondrial respiratory chain disease. NAD+ and PPAR-modifying drugs may confer benefits with respect to lifespan in these short-lived mutant worms. Analysis of gas-1(fc21) electron transport chain complex I mutants treated either starting in development or in young adulthood only with nicotinic acid (1 mM), resveratrol (50 microM), rosiglitazone (5 mM) or fenofibrate (14 microM) is presented. The goal is to detect transcriptional changes in clusters of genes using gene set enrichment analysis to explain treament effects in these mutant worms.

Description
Limited access to large samples and independent replication cohorts precludes genome-wide association (GWA) studies of rare but complex traits. To localize candidate genes in an on-going study utilizing family-based GWA, a novel exploratory analysis was first tested on 1,774 major histocompatibility complex single nucleotide polymorphisms (SNPs) in 240 DNA samples from 80 children with primary liver transplantation (LTx), and their biological parents. Genotyping was performed using the Illumina HumHap550k SNP BeadArray; the genotype calls for the 1813 SNPs in the MHC region are provided in the genotype_data.zip supplementary file linked to this series (see README file in the zip archive for more information).

Description
DAC represents a therapeutic option for elderly AML patients. However, there is still a lack of data for valid biomarkers in respect to response. We executed a gene expression analysis prior to treatment to evaluate gene expression patterns associated with response that might be used to predict DAC therapy outcome. In our cohort an objective ORR of 27% was seen. In a class comparison analysis 333 genes were identified that correlated significantly with response. In this gene signature genes that were prior associated with adverse outcome to regular chemotherapy were enriched in the response group. Interistingly for the non response cohort TSG showed an increased expression, suggesting that epigenetic silencing due to promoter hypermethylation might play a lesser role in theses leukemia pathogenesis.
