Affymetrix Human Genome U219 Array (hgu219)
Description
We performed a pharmacotranscriptomic analysis of a human neuroblastoma cell line (SK-N-SH) exposed to risperidone to identify molecular mechanisms involved in the cellular response to risperidone and thus identify candidate genes for pharmacogenetic studies.

Description
Mephedrone (Meph) is a novel psychostimulant whose recreational consumption is often associated to other drugs, especially alcohol (EtOH). This kind of drug consumption during adolescence is a matter of concern. We studied, in adolescent CD-1 mice, whether low-moderate doses of EtOH could enhance the psychostimulant (locomotor acivity) and reinforcing (conditioned place preference, CPP) effects of mephedrone. Simultaneously we also determined the most relevant transcriptional changes associated to a reinforcing treatment. A single dose of Meph (10 mg/kg, sc) induced an increase of about 100% in locomotor activity, which was a further enhanced by 40% when associated with a dose of EtOH (1 g/kg). The hyperlocomotion was partially antagonized by ketanserin and haloperidol, but only haloperidol blocked the potentiation induced by EtOH. Furthermore, Meph (25 mg/kg) induced significant positive conditioning, which increased by 70% when administered with 0.75 mg/kg EtOH. Microarray analysis of mRNA extracted from anterior striata of the mice used in CPP experiments reported significant modifications in genes related with neurotransmission and synaptic plasticity, which were further validated by Real-time PCR for all three drug-treated groups.

Description
Introduction: The genetic origin of familial combined hyperlipidemia (FCH) is not well understood. We used microarray profiling of peripheral blood monocytes to search novel genes and pathways involved in FCH. Methods: Fasting plasma for determination of lipid profiles, inflammatory molecules, and adipokines was obtained and peripheral blood monocytes were isolated from male FCH patients basally and after 4 weeks of atorvastatin treatment. Sex-, age- and adiposity-matched controls were also studied. Gene expression profile was analyzed using Affymetrix Human Genome U133A 2.0 GeneChip arrays. Results: Analysis of gene expression by cDNA microarrays showed that 82 genes were differentially expressed in FCH monocytes compared to controls. Atorvastatin treatment modified the expression of 87 genes. Changes in the expression of some genes, confirmed by real time RT-PCR, (CD36, leucine-rich repeats and immunoglobulin-like domains-1, tissue factor pathway inhibitor 2, myeloid cell nuclear differentiation antigen tumor necrosis factor receptor superfamily, member 25 and CD96) may be related to a proinflammatory environment in FCH monocytes, which is partially reversed by atorvastatin. Higher plasma levels of triglycerides and free fatty acids and lower levels of adiponectin in FCH patients could also trigger changes in gene expression that atorvastatin cannot modify. Conclusions: Our results demonstrate clear differences in gene expression in FCH monocytes compared with those of matched healthy controls, some of which are influenced by atorvastatin treatment.

Description
Low levels of the cell cycle regulator p27Kip1 are associated with a worse outcome in many tumor types. We report here a new regulatory role of p27Kip1 as a transcriptional regulator. In association with transcriptional factors such as ETS and E2F4 and co-repressors like p130, HDACs and mSin3A, p27 binds to promoters of multiple genes leading to their repression. The p27-target genes participate in RNA processing, translation, respiration and cell cycle. Remarkably, p27-target genes are over-expressed in different human tumors in tight association with a poor clinical prognosis. We also observed a clear correlation between low levels of p27 and over-expression of p27-target genes in tumors. Overall, our findings indicate new tumor suppressor roles of p271 as a transcriptional regulator of genes relevant for oncogenesis.

Description
Alterations in the presence of sperm RNAs have been identified using microarrays in teratozoospermic (abnormal morphology) or other types of infertile patients. However, so far no studies had been reported on the sperm RNA content using microarrays in asthenozoospermic patients (low motility).
